Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    Security Fix(es) :
    
    * It was found that the Linux kernel's IPv6 implementation mishandled
    socket options. A local attacker could abuse concurrent access to the
    socket options to escalate their privileges, or cause a denial of
    service (use-after-free and system crash) via a crafted sendmsg system
    call. (CVE-2016-3841, Important)

    "According to the versions of the kernel packages installed, the
    EulerOS Virtualization for ARM 64 installation on the remote host is
    affected by the following vulnerabilities :
    
      - An integer overflow flaw was found in the way the Linux
        kernel's netfilter connection tracking implementation
        loaded extensions. An attacker on a local network could
        potentially send a sequence of specially crafted
        packets that would initiate the loading of a large
        number of extensions, causing the targeted system in
        that network to crash.(CVE-2014-9715i1/4%0
    
      - A flaw was found in the Linux kernel which could cause
        a kernel panic when restoring machine specific
        registers on the PowerPC platform. Incorrect
        transactional memory state registers could
        inadvertently change the call path on return from
        userspace and cause the kernel to enter an unknown
        state and crash.(CVE-2015-8844i1/4%0
    
      - A timing flaw was found in the Chrome EC driver in the
        Linux kernel. An attacker could abuse timing to skip
        validation checks to copy additional data from
        userspace possibly increasing privilege or crashing the
        system.(CVE-2016-6156i1/4%0
    
      - A race condition flaw was found in the way the Linux
        kernel's IPC subsystem initialized certain fields in an
        IPC object structure that were later used for
        permission checking before inserting the object into a
        globally visible list. A local, unprivileged user could
        potentially use this flaw to elevate their privileges
        on the system.(CVE-2015-7613i1/4%0
    
      - A path length checking flaw was found in Linux kernels
        built with UDF file system (CONFIG_UDF_FS) support. An
        attacker able to mount a corrupted/malicious UDF file
        system image could use this flaw to leak kernel memory
        to user-space.(CVE-2014-9731i1/4%0
    
      - A race condition leading to a NULL pointer dereference
        was found in the Linux kernel's Link Layer Control
        implementation. A local attacker with access to ping
        sockets could use this flaw to crash the
        system.(CVE-2017-2671i1/4%0
    
      - The f2fs implementation in the Linux kernel, before
        4.14, mishandles reference counts associated with
        f2fs_wait_discard_bios calls. This allows local users
        to cause a denial of service (BUG), as demonstrated by
        fstrim.(CVE-2017-18200i1/4%0
    
      - The LIST_POISON feature in include/linux/poison.h in
        the Linux kernel before 4.3, as used in Android 6.0.1
        before 2016-03-01, does not properly consider the
        relationship to the mmap_min_addr value, which makes it
        easier for attackers to bypass a poison-pointer
        protection mechanism by triggering the use of an
        uninitialized list entry, aka Android internal bug
        26186802, a different vulnerability than
        CVE-2015-3636.(CVE-2016-0821i1/4%0
    
      - The xsave/xrstor implementation in
        arch/x86/include/asm/xsave.h in the Linux kernel before
        3.19.2 creates certain .altinstr_replacement pointers
        and consequently does not provide any protection
        against instruction faulting, which allows local users
        to cause a denial of service (panic) by triggering a
        fault, as demonstrated by an unaligned memory operand
        or a non-canonical address memory
        operand.(CVE-2015-2672i1/4%0
    
      - The n_tty_write function in drivers/tty/n_tty.c in the
        Linux kernel through 3.14.3 does not properly manage
        tty driver access in the 'LECHO i1/4+ !OPOST' case, which
        allows local users to cause a denial of service (memory
        corruption and system crash) or gain privileges by
        triggering a race condition involving read and write
        operations with long strings.(CVE-2014-0196i1/4%0
    
      - In the Linux kernel through 4.14.13,
        drivers/block/loop.c mishandles lo_release
        serialization, which allows attackers to cause a denial
        of service (__lock_acquire use-after-free) or possibly
        have unspecified other impact.(CVE-2018-5344i1/4%0
    
      - The lbs_debugfs_write function in
        drivers/net/wireless/libertas/debugfs.c in the Linux
        kernel through 3.12.1 allows local users to cause a
        denial of service (OOPS) by leveraging root privileges
        for a zero-length write operation.(CVE-2013-6378i1/4%0
    
      - A NULL-pointer dereference vulnerability was discovered
        in the Linux kernel. The kernel's Reliable Datagram
        Sockets (RDS) protocol implementation did not verify
        that an underlying transport existed before creating a
        connection to a remote server. A local system user
        could exploit this flaw to crash the system by creating
        sockets at specific times to trigger a NULL pointer
        dereference.(CVE-2015-6937i1/4%0
    
      - A stack buffer overflow flaw was found in the way the
        Bluetooth subsystem of the Linux kernel processed
        pending L2CAP configuration responses from a client. On
        systems with the stack protection feature enabled in
        the kernel (CONFIG_CC_STACKPROTECTOR=y, which is
        enabled on all architectures other than s390x and
        ppc64le), an unauthenticated attacker able to initiate
        a connection to a system via Bluetooth could use this
        flaw to crash the system. Due to the nature of the
        stack protection feature, code execution cannot be
        fully ruled out, although we believe it is unlikely. On
        systems without the stack protection feature (ppc64le
        the Bluetooth modules are not built on s390x), an
        unauthenticated attacker able to initiate a connection
        to a system via Bluetooth could use this flaw to
        remotely execute arbitrary code on the system with ring
        0 (kernel) privileges.(CVE-2017-1000251i1/4%0
    
      - Integer signedness error in the MSM QDSP6 audio driver
        for the Linux kernel 3.x, as used in Qualcomm
        Innovation Center (QuIC) Android contributions for MSM
        devices and other products, allows attackers to gain
        privileges or cause a denial of service (memory
        corruption) via a crafted application that makes an
        ioctl call.(CVE-2016-2066i1/4%0
    
      - The bcm_char_ioctl function in
        drivers/staging/bcm/Bcmchar.c in the Linux kernel
        before 3.12 does not initialize a certain data
        structure, which allows local users to obtain sensitive
        information from kernel memory via an
        IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl
        call.(CVE-2013-4515i1/4%0
    
      - A flaw was found in the way the Linux kernel's Stream
        Control Transmission Protocol (SCTP) implementation
        handled malformed Address Configuration Change Chunks
        (ASCONF). A remote attacker could use either of these
        flaws to crash the system.(CVE-2014-3673i1/4%0
    
      - It was found that paravirt_patch_call/jump() functions
        in the arch/x86/kernel/paravirt.c in the Linux kernel
        mishandles certain indirect calls, which makes it
        easier for attackers to conduct Spectre-v2 attacks
        against paravirtualized guests.(CVE-2018-15594i1/4%0
    
      - It was found that the Linux kernel's KVM implementation
        did not ensure that the host CR4 control register value
        remained unchanged across VM entries on the same
        virtual CPU. A local, unprivileged user could use this
        flaw to cause a denial of service on the
        system.(CVE-2014-3690i1/4%0
    
      - A flaw was found in the Linux kernel's ext4 filesystem.
        A local user can cause an out-of-bound write in
        jbd2_journal_dirty_metadata(), a denial of service, and
        a system crash by mounting and operating on a crafted
        ext4 filesystem image.(CVE-2018-10883i1/4%0

    An update for kernel is now available for Red Hat Enterprise Linux 7.
    
    Red Hat Product Security has rated this update as having a security
    impact of Important. A Common Vulnerability Scoring System (CVSS) base
    score, which gives a detailed severity rating, is available for each
    vulnerability from the CVE link(s) in the References section.
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    Security Fix(es) :
    
    * It was found that the Linux kernel's IPv6 implementation mishandled
    socket options. A local attacker could abuse concurrent access to the
    socket options to escalate their privileges, or cause a denial of
    service (use-after-free and system crash) via a crafted sendmsg system
    call. (CVE-2016-3841, Important)
    
    * Several Moderate and Low impact security issues were found in the
    Linux kernel. Space precludes documenting each of these issues in this
    advisory. Refer to the CVE links in the References section for a
    description of each of these vulnerabilities. (CVE-2013-4312,

    "An update for kernel is now available for Red Hat Enterprise Linux 7.
    
    Red Hat Product Security has rated this update as having a security
    impact of Important. A Common Vulnerability Scoring System (CVSS) base
    score, which gives a detailed severity rating, is available for each
    vulnerability from the CVE link(s) in the References section.
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    Security Fix(es) :
    
    * It was found that the Linux kernel's IPv6 implementation mishandled
    socket options. A local attacker could abuse concurrent access to the
    socket options to escalate their privileges, or cause a denial of
    service (use-after-free and system crash) via a crafted sendmsg system
    call. (CVE-2016-3841, Important)
    
    * Several Moderate and Low impact security issues were found in the
    Linux kernel. Space precludes documenting each of these issues in this
    advisory. Refer to the CVE links in the References section for a
    description of each of these vulnerabilities. (CVE-2013-4312,
    CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844,

        NOTE: the author of the LZO algorithms says 'the Linux

        certain backport in the TCP Fast Open implementation
        for the Linux kernel before 3.18 does not properly
        maintain a count value, which allow local users to
        cause a denial of service (system crash) via the Fast
        Open feature, as demonstrated by visiting the
        chrome://flags/#enable-tcp-fast-open URL when using
        certain 3.10.x through 3.16.x kernel builds, including
        longterm-maintenance releases and ckt (aka Canonical
        Kernel Team) builds.(CVE-2015-3332)An elevation of
        privilege vulnerability in the kernel scsi driver.
        Product: Android. Versions: Android kernel. Android ID
        A-65023233.(CVE-2017-13168)An issue was discovered in
        drivers/i2c/i2c-core-smbus.c in the Linux kernel before
        4.14.15. There is an out of bounds write in the
        function i2c_smbus_xfer_emulated.(CVE-2017-18551)An
        issue was discovered in net/ipv6/ip6mr.c in the Linux
        kernel before 4.11. By setting a specific socket
        option, an attacker can control a pointer in kernel
        land and cause an inet_csk_listen_stop general
        protection fault, or potentially execute arbitrary code
        under certain circumstances. The issue can be triggered
        as root (e.g., inside a default LXC container or with
        the CAP_NET_ADMIN capability) or after namespace
        unsharing. This occurs because sk_type and protocol are
        not checked in the appropriate part of the ip6_mroute_*
        functions. NOTE: this affects Linux distributions that
        use 4.9.x longterm kernels before
        4.9.187.(CVE-2017-18509)An issue was discovered in the
        Linux kernel before 4.14.11. A double free may be
        caused by the function allocate_trace_buffer in the
        file kernel/trace/trace.c.(CVE-2017-18595)An issue was
        discovered in the Linux kernel through 4.17.10. There
        is a NULL pointer dereference and panic in
        hfsplus_lookup() in fs/hfsplus/dir.c when opening a
        file (that is purportedly a hard link) in an hfs+
        filesystem that has malformed catalog data, and is
        mounted read-only without a metadata
        directory.(CVE-2018-14617)An issue was discovered in
        write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in
        the Linux kernel through 5.3.2. The cxgb4 driver is
        directly calling dma_map_single (a DMA function) from a
        stack variable. This could allow an attacker to trigger
        a Denial of Service, exploitable if this driver is used
        on an architecture for which this stack/DMA interaction
        has security relevance.(CVE-2019-17075)Double free
        vulnerability in the snd_usbmidi_create function in
        sound/usb/midi.c in the Linux kernel before 4.5 allows
        physically proximate attackers to cause a denial of
        service (panic) or possibly have unspecified other
        impact via vectors involving an invalid USB
        descriptor.(CVE-2016-2384)fsamespace.c in the Linux
        kernel through 3.16.1 does not properly restrict
        clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and
        changing MNT_ATIME_MASK during a remount of a bind
        mount, which allows local users to gain privileges,
        interfere with backups and auditing on systems that had
        atime enabled, or cause a denial of service (excessive
        filesystem updating) on systems that had atime disabled
        via a 'mount -o remount' command within a user
        namespace.(CVE-2014-5207)fs/overlayfs/dir.c in the
        OverlayFS filesystem implementation in the Linux kernel
        before 4.6 does not properly verify the upper dentry
        before proceeding with unlink and rename system-call
        processing, which allows local users to cause a denial
        of service (system crash) via a rename system call that
        specifies a self-hardlink.(CVE-2016-6197)In the Linux
        kernel before 4.1.4, a buffer overflow occurs when
        checking userspace params in
        drivers/media/dvb-frontends/cx24116.c. The maximum size
        for a DiSEqC command is 6, according to the userspace
        API. However, the code allows larger values such as
        23.(CVE-2015-9289)In the Linux kernel through 5.3.2,
        cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c
        does not reject a long SSID IE, leading to a Buffer
        Overflow.(CVE-2019-17133)Insufficient access control in
        the Intel(R) PROSet/Wireless WiFi Software driver
        before version 21.10 may allow an unauthenticated user
        to potentially enable denial of service via adjacent
        access.(CVE-2019-0136)Linux distributions that have not
        patched their long-term kernels with
        https://git.kernel.org/linus/a87938b2e246b81b4fb713edb3
        71a9fa3c5c3c86 (committed on April 14, 2015). This
        kernel vulnerability was fixed in April 2015 by commit
        a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to
        Linux 3.10.77 in May 2015), but it was not recognized
        as a security threat. With
        CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a
        normal top-down address allocation strategy,
        load_elf_binary() will attempt to map a PIE binary into
        an address range immediately below mm->mmap_base.
        Unfortunately, load_elf_ binary() does not take account
        of the need to allocate sufficient space for the entire
        binary which means that, while the first PT_LOAD
        segment is mapped below mm->mmap_base, the subsequent
        PT_LOAD segment(s) end up being mapped above
        mm->mmap_base into the are that is supposed to be the
        'gap' between the stack and the
        binary.(CVE-2017-1000253)Race condition in the
        sclp_ctl_ioctl_sccb function in
        drivers/s390/char/sclp_ctl.c in the Linux kernel before
        4.6 allows local users to obtain sensitive information
        from kernel memory by changing a certain length value,
        aka a 'double fetch'
        vulnerability.(CVE-2016-6130)rtl_p2p_noa_ie in drivers
        et/wireless/realtek/rtlwifi/ps.c in the Linux kernel
        through 5.3.6 lacks a certain upper-bound check,
        leading to a buffer
        overflow.(CVE-2019-17666)sound/core/timer.c in the
        Linux kernel through 4.6 does not initialize certain r1
        data structures, which allows local users to obtain
        sensitive information from kernel stack memory via
        crafted use of the ALSA timer interface, related to the
        (1) snd_timer_user_ccallback and (2)
        snd_timer_user_tinterrupt
        functions.(CVE-2016-4578)Systems with microprocessors
        utilizing speculative execution and branch prediction
        may allow unauthorized disclosure of information to an
        attacker with local user access via a side-channel
        analysis.(CVE-2017-5753)The acm_probe function in
        drivers/usb/class/cdc-acm.c in the Linux kernel before
        4.5.1 allows physically proximate attackers to cause a
        denial of service (NULL pointer dereference and system
        crash) via a USB device without both a control and a
        data endpoint descriptor.(CVE-2016-3138)The
        arcmsr_iop_message_xfer function in
        drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel
        through 4.8.2 does not restrict a certain length field,
        which allows local users to gain privileges or cause a
        denial of service (heap-based buffer overflow) via an
        ARCMSR_MESSAGE_WRITE_WQBUFFER control
        code.(CVE-2016-7425)The ati_remote2_probe function in
        drivers/input/misc/ati_remote2.c in the Linux kernel
        before 4.5.1 allows physically proximate attackers to
        cause a denial of service (NULL pointer dereference and
        system crash) via a crafted endpoints value in a USB
        device descriptor.(CVE-2016-2185)The
        create_fixed_stream_quirk function in
        sound/usb/quirks.c in the snd-usb-audio driver in the
        Linux kernel before 4.5.1 allows physically proximate
        attackers to cause a denial of service (NULL pointer
        dereference or double free, and system crash) via a
        crafted endpoints value in a USB device
        descriptor.(CVE-2016-2184)The digi_port_init function
        in drivers/usb/serial/digi_acceleport.c in the Linux
        kernel before 4.5.1 allows physically proximate
        attackers to cause a denial of service (NULL pointer
        dereference and system crash) via a crafted endpoints
        value in a USB device descriptor.(CVE-2016-3140)The
        do_remount function in fsamespace.c in the Linux kernel
        through 3.16.1 does not maintain the MNT_LOCK_READONLY
        bit across a remount of a bind mount, which allows
        local users to bypass an intended read-only restriction
        and defeat certain sandbox protection mechanisms via a
        'mount -o remount' command within a user
        namespace.(CVE-2014-5206)The gtco_probe function in
        drivers/input/tablet/gtco.c in the Linux kernel through
        4.5.2 allows physically proximate attackers to cause a
        denial of service (NULL pointer dereference and system
        crash) via a crafted endpoints value in a USB device
        descriptor.(CVE-2016-2187)The hub_activate function in
        drivers/usb/core/hub.c in the Linux kernel before 4.3.5
        does not properly maintain a hub-interface data
        structure, which allows physically proximate attackers
        to cause a denial of service (invalid memory access and
        system crash) or possibly have unspecified other impact
        by unplugging a USB hub device.(CVE-2015-8816)The
        ims_pcu_parse_cdc_data function in
        drivers/input/misc/ims-pcu.c in the Linux kernel before
        4.5.1 allows physically proximate attackers to cause a
        denial of service (system crash) via a USB device
        without both a master and a slave
        interface.(CVE-2016-3689)The Linux Kernel running on
        AMD64 systems will sometimes map the contents of PIE
        executable, the heap or ld.so to where the stack is
        mapped allowing attackers to more easily manipulate the
        stack. Linux Kernel version 4.11.5 is
        affected.(CVE-2017-1000379)The powermate_probe function
        in drivers/input/misc/powermate.c in the Linux kernel
        before 4.5.1 allows physically proximate attackers to
        cause a denial of service (NULL pointer dereference and
        system crash) via a crafted endpoints value in a USB
        device descriptor.(CVE-2016-2186)The signal
        implementation in the Linux kernel before 4.3.5 on
        powerpc platforms does not check for an MSR with both
        the S and T bits set, which allows local users to cause
        a denial of service (TM Bad Thing exception and panic)
        via a crafted application.(CVE-2015-8844)The
        snd_timer_user_params function in sound/core/timer.c in
        the Linux kernel through 4.6 does not initialize a
        certain data structure, which allows local users to
        obtain sensitive information from kernel stack memory
        via crafted use of the ALSA timer
        interface.(CVE-2016-4569)The tm_reclaim_thread function
        in arch/powerpc/kernel/process.c in the Linux kernel
        before 4.4.1 on powerpc platforms does not ensure that
        TM suspend mode exists before proceeding with a
        tm_reclaim call, which allows local users to cause a
        denial of service (TM Bad Thing exception and panic)
        via a crafted application.(CVE-2015-8845)The VFS
        subsystem in the Linux kernel 3.x provides an
        incomplete set of requirements for setattr operations
        that underspecifies removing extended privilege
        attributes, which allows local users to cause a denial
        of service (capability stripping) via a failed
        invocation of a system call, as demonstrated by using
        chown to remove a capability from the ping or Wireshark
        dumpcap program.(CVE-2015-1350)The wacom_probe function
        in drivers/input/tablet/wacom_sys.c in the Linux kernel
        before 3.17 allows physically proximate attackers to
        cause a denial of service (NULL pointer dereference and
        system crash) via a crafted endpoints value in a USB
        device descriptor.(CVE-2016-3139)

    The kernel-rt packages provide the Real Time Linux Kernel, which
    enables fine-tuning for systems with extremely high determinism
    requirements.
    
    Security Fix(es) :
    
    * It was found that the Linux kernel's IPv6 implementation mishandled
    socket options. A local attacker could abuse concurrent access to the
    socket options to escalate their privileges, or cause a denial of
    service (use-after-free and system crash) via a crafted sendmsg system
    call. (CVE-2016-3841, Important)
    
    * Several Moderate and Low impact security issues were found in the
