Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

    out-of-bounds write) via a crafted
    device.(CVE-2013-2890i1/4%0

  - An issue where a provided address with access_ok() is
    not checked was discovered in
    i915_gem_execbuffer2_ioctl in
    drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux
    kernel through 4.19.13. A local attacker can craft a
    malicious IOCTL function call to overwrite arbitrary
    kernel memory, resulting in a Denial of Service or
    privilege escalation.(CVE-2018-20669i1/4%0

  - It was found that the permission checks performed by
    the Linux kernel when a netlink message was received
    were not sufficient. A local, unprivileged user could
    potentially bypass these restrictions by passing a
    netlink socket as stdout or stderr to a more privileged
    process and altering the output of this
    process.(CVE-2014-0181i1/4%0

  - An issue was discovered in the XFS filesystem in
    fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A
    NULL pointer dereference may occur for a corrupted xfs
    image after xfs_da_shrink_inode() is called with a NULL
    bp. This can lead to a system crash and a denial of
    service.(CVE-2018-13094i1/4%0

  - The irda_setsockopt function in net/irda/af_irda.c in
    the Linux kernel, through 4.16, allows local users to
    cause a denial of service (due to a use-after-free of
    the ias_object and a system crash) or possibly have
    unspecified other impact by leveraging an AF_IRDA
    socket.(CVE-2018-6555i1/4%0

  - The x86/fpu (Floating Point Unit) subsystem in the
    Linux kernel, when a processor supports the xsave
    feature but not the xsaves feature, does not correctly
    handle attempts to set reserved bits in the xstate
    header via the ptrace() or rt_sigreturn() system call.
    This allows local users to read the FPU registers of
    other processes on the system, related to
    arch/x86/kernel/fpu/regset.c and
    arch/x86/kernel/fpu/signal.c.(CVE-2017-15537i1/4%0

  - The fst_get_iface function in drivers/net/wan/farsync.c
    in the Linux kernel before 3.11.7 does not properly
    initialize a certain data structure, which allows local
    users to obtain sensitive information from kernel
    memory by leveraging the CAP_NET_ADMIN capability for
    an SIOCWANDEV ioctl call.(CVE-2014-1444i1/4%0

  - In the Linux kernel, through 4.15.4, the floppy driver
    reveals the addresses of kernel functions and global
    variables using printk calls within the function
    show_floppy in drivers/block/floppy.c. An attacker can
    read this information from dmesg and use the addresses
    to find the locations of kernel code and data and
    bypass kernel security protections such as
    KASLR.(CVE-2018-7273i1/4%0

  - A flaw in 'arch/arm64/kernel/sys.c' in the Linux kernel
    allows local users to bypass the 'strict page
    permissions' protection mechanism and modify the
    system-call table and, consequently, gain privileges by
    leveraging write access.(CVE-2015-8967i1/4%0

  - The Linux kernel before 3.11 on ARM platforms, as used
    in Android before 2016-08-05 on Nexus 5 and 7 (2013)
    devices, does not properly consider user-space access
    to the TPIDRURW register, which allows local users to
    gain privileges via a crafted application, aka Android
    internal bug 28749743 and Qualcomm internal bug
    CR561044.(CVE-2014-9870i1/4%0

  - A NULL pointer dereference security flaw was found in
    the Linux kernel in the vcpu_scan_ioapic() function in
    arch/x86/kvm/x86.c. This allows local users with
    certain privileges to cause a denial of service via a
    crafted system call to the KVM
    subsystem.(CVE-2018-19407i1/4%0

  - It was found that current implementation of kl5kusb105
    driver failed to detect short transfers when attempting
    to read the line state and logged the content of the
    uninitialized heap transfer buffer.(CVE-2017-5549i1/4%0

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - 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 snd_compr_tstamp function in sound/core/compress_offload.c in the Linux kernel through 4.7, as used in Android before 2016-08-05 on Nexus 5 and 7 (2013) devices, does not properly initialize a timestamp data structure, which allows attackers to obtain sensitive information via a crafted application, aka Android internal bug 28770164 and Qualcomm internal bug CR568717.(CVE-2014-9892) - A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering kfifo_alloc() failures, aka CID-a7b2df76b42b.(CVE-2019-19054) - A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.(CVE-2019-19060) - A memory leak in the adis_update_scan_mode_burst() function in drivers/iio/imu/adis_buffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-9c0530e898f3.(CVE-2019-19061) - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042.(CVE-2019-19062) - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.(CVE-2019-18808) - In ashmem_ioctl of ashmem.c, there is an out-of-bounds write due to insufficient locking when accessing asma. This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-66954097.(CVE-2017-13216) - A 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) - The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message.(CVE-2016-4486) - The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.(CVE-2017-5897) - In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation.(CVE-2017-7482) - A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest.

    CID-1acb8f2a7a9f.(CVE-2019-18806)

  - An issue was discovered in the fd_locked_ioctl function
    in drivers/block/floppy.c in the Linux kernel through
    4.15.7. The floppy driver will copy a kernel pointer to
    user memory in response to the FDGETPRM ioctl. An
    attacker can send the FDGETPRM ioctl and use the
    obtained kernel pointer to discover the location of
    kernel code and data and bypass kernel security
    protections such as KASLR.(CVE-2018-7755)

  - The usbvision driver in the Linux kernel package
    3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red
    Hat Enterprise Linux (RHEL) 7.1 allows physically
    proximate attackers to cause a denial of service
    (panic) via a nonzero bInterfaceNumber value in a USB
    device descriptor.(CVE-2015-7833)

  - A flaw that allowed an attacker to corrupt memory and
    possibly escalate privileges was found in the mwifiex
    kernel module while connecting to a malicious wireless
    network.(CVE-2019-3846)

  - drivers/net/wireless/marvell/libertas/if_sdio.c in the
    Linux kernel 5.2.14 does not check the alloc_workqueue
    return value, leading to a NULL pointer
    dereference.(CVE-2019-16232)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the
    Linux kernel 5.2.14 does not check the alloc_workqueue

    dereference.(CVE-2019-16234)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14
    does not check the alloc_workqueue return value,
    leading to a NULL pointer dereference.(CVE-2019-16231)

  - 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)

  - A flaw was found in the Linux kernel. A heap based
    buffer overflow in mwifiex_uap_parse_tail_ies function
    in drivers/net/wireless/marvell/mwifiex/ie.c might lead
    to memory corruption and possibly other
    consequences.(CVE-2019-10126)

  - The Bluetooth BR/EDR specification up to and including
    version 5.1 permits sufficiently low encryption key
    length and does not prevent an attacker from
    influencing the key length negotiation. This allows
    practical brute-force attacks (aka 'KNOB') that can
    decrypt traffic and inject arbitrary ciphertext without
    the victim noticing.(CVE-2019-9506)

  - An issue was discovered in net/wireless/nl80211.c in
    the Linux kernel through 5.2.17. It does not check the
    length of variable elements in a beacon head, leading
    to a buffer overflow.(CVE-2019-16746)

  - In the hidp_process_report in bluetooth, there is an
    integer overflow. This could lead to an out of bounds
    write with no additional execution privileges needed.
    User interaction is not needed for exploitation.
    Product: Android Versions: Android kernel Android ID:

  - 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)

  - rtl_p2p_noa_ie in
    drivers/net/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)

    3.13 on ARM platforms, as used in Android before
    2016-08-05 on Nexus 5 and 7 (2013) devices, does not
    prevent executable DMA mappings, which might allow
    local users to gain privileges via a crafted
    application, aka Android internal bug 28803642 and
    Qualcomm internal bug CR642735.(CVE-2014-9888)

  - 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)

  - The rds_ib_xmit function in net/rds/ib_send.c in the
    Reliable Datagram Sockets (RDS) protocol implementation
    in the Linux kernel 3.7.4 and earlier allows local
    users to cause a denial of service (BUG_ON and kernel
    panic) by establishing an RDS connection with the
    source IP address equal to the IPoIB interface's own IP
    address, as demonstrated by rds-ping.(CVE-2012-2372)

  - 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)

  - A memory leak in the bfad_im_get_stats() function in
    drivers/scsi/bfa/bfad_attr.c in the Linux kernel

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0
    allows local users to bypass the 'strict page
    permissions' protection mechanism and modify the
    system-call table, and consequently gain privileges, by
    leveraging write access.(CVE-2015-8967)

  - arch/arm64/kernel/perf_event.c in the Linux kernel
    before 4.1 on arm64 platforms allows local users to
    gain privileges or cause a denial of service (invalid
    pointer dereference) via vectors involving events that
    are mishandled during a span of multiple HW
    PMUs.(CVE-2015-8955)

  - The __clear_user function in
    arch/arm64/lib/clear_user.S in the Linux kernel before
    3.17.4 on the ARM64 platform allows local users to
    cause a denial of service (system crash) by reading one
    byte beyond a /dev/zero page boundary.(CVE-2014-7843)

  - The x86/fpu (Floating Point Unit) subsystem in the
    Linux kernel before 4.13.5, when a processor supports
    the xsave feature but not the xsaves feature, does not
    correctly handle attempts to set reserved bits in the
    xstate header via the ptrace() or rt_sigreturn() system
    call, allowing local users to read the FPU registers of
    other processes on the system, related to
    arch/x86/kernel/fpu/regset.c and
    arch/x86/kernel/fpu/signal.c.(CVE-2017-15537)

    in Android before 2016-08-05 on Nexus 5 and 7 (2013)
    devices, does not properly consider user-space access
    to the TPIDRURW register, which allows local users to
    gain privileges via a crafted application, aka Android
    internal bug 28749743 and Qualcomm internal bug
    CR561044.(CVE-2014-9870)

  - ** DISPUTED ** Race condition in the
    store_int_with_restart() function in
    arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel
    through 4.15.7 allows local users to cause a denial of
    service (panic) by leveraging root access to write to
    the check_interval file in a
    /sys/devices/system/machinecheck/machinecheck
    directory. NOTE: a third party has indicated that this
    report is not security relevant.(CVE-2018-7995)

  - arch/x86/kernel/entry_32.S in the Linux kernel through
    3.15.1 on 32-bit x86 platforms, when syscall auditing
    is enabled and the sep CPU feature flag is set, allows
    local users to cause a denial of service (OOPS and
    system crash) via an invalid syscall number, as
    demonstrated by number 1000.(CVE-2014-4508)

  - arch/x86/kernel/tls.c in the Thread Local Storage (TLS)
    implementation in the Linux kernel through 3.18.1
    allows local users to bypass the espfix protection
    mechanism, and consequently makes it easier for local
    users to bypass the ASLR protection mechanism, via a
    crafted application that makes a set_thread_area system
    call and later reads a 16-bit value.(CVE-2014-8133)

  - arch/mips/include/asm/thread_info.h in the Linux kernel
    before 3.14.8 on the MIPS platform does not configure
    _TIF_SECCOMP checks on the fast system-call path, which
    allows local users to bypass intended PR_SET_SECCOMP
    restrictions by executing a crafted application without
    invoking a trace or audit subsystem.(CVE-2014-4157)

  - Integer signedness error in the oz_hcd_get_desc_cnf
    function in drivers/staging/ozwpan/ozhcd.c in the
    OZWPAN driver in the Linux kernel through 4.0.5 allows
    remote attackers to cause a denial of service (system
    crash) or possibly execute arbitrary code via a crafted
    packet.(CVE-2015-4001)

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver
    in the Linux kernel through 4.0.5 does not ensure that
    certain length values are sufficiently large, which
    allows remote attackers to cause a denial of service
    (system crash or large loop) or possibly execute
    arbitrary code via a crafted packet, related to the (1)
    oz_usb_rx and (2) oz_usb_handle_ep_data
    functions.(CVE-2015-4002)

  - The oz_usb_handle_ep_data function in
    drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver
    in the Linux kernel through 4.0.5 allows remote

  - 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)

  - The saa7164_bus_get function in
    drivers/media/pci/saa7164/saa7164-bus.c in the Linux
    kernel through 4.11.5 allows local users to cause a
    denial of service (out-of-bounds array access) or
    possibly have unspecified other impact by changing a
    certain sequence-number value, aka a 'double fetch'
    vulnerability.(CVE-2017-8831)
