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.

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - An information-leak vulnerability was found in the kernel when it truncated a file to a smaller size which consisted of an inline extent that was compressed. The data between the new file size and the old file size was not discarded and the number of bytes used by the inode were not correctly decremented, which gave the wrong report for callers of the stat(2) syscall. This wasted metadata space and allowed for the truncated data to be leaked, and data corruption or loss to occur. A caller of the clone ioctl could exploit this flaw by using only standard file-system operations without root access to read the truncated data.(CVE-2015-8374) - A flaw was found in the Linux kernel

"According to the versions of the kernel packages installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerabilities :

  - An information-leak vulnerability was found in the
    kernel when it truncated a file to a smaller size which
    consisted of an inline extent that was compressed. The
    data between the new file size and the old file size
    was not discarded and the number of bytes used by the
    inode were not correctly decremented, which gave the
    wrong report for callers of the stat(2) syscall. This
    wasted metadata space and allowed for the truncated
    data to be leaked, and data corruption or loss to
    occur. A caller of the clone ioctl could exploit this
    flaw by using only standard file-system operations
    without root access to read the truncated
    data.(CVE-2015-8374)

  - A flaw was found in the Linux kernel's key management
    system where it was possible for an attacker to
    escalate privileges or crash the machine. If a user key
    gets negatively instantiated, an error code is cached
    in the payload area. A negatively instantiated key may
    be then be positively instantiated by updating it with
    valid data. However, the -i1/4zupdate key type method
    must be aware that the error code may be
    there.(CVE-2015-8539)

  - A NULL pointer dereference flaw was found in the way
    the Linux kernel's network subsystem handled socket
    creation with an invalid protocol identifier. A local
    user could use this flaw to crash the
    system.(CVE-2015-8543)

  - An out-of-bounds flaw was found in the kernel, where
    the length of the sockaddr parameter was not checked in
    the pptp_bind() and pptp_connect() functions. As a
    result, more kernel memory was copied out than
    required, leaking information from the kernel stack
    (including kernel addresses). A local system user could
    exploit this flaw to bypass kernel ASLR or leak other
    information.(CVE-2015-8569)

  - An out-of-bounds flaw was found in the kernel, where
    the sco_sock_bind() function (bluetooth/sco) did not
    check the length of its sockaddr parameter. As a
    result, more kernel memory was copied out than
    required, leaking information from the kernel stack
    (including kernel addresses). A local user could
    exploit this flaw to bypass kernel ASLR or leak other
    information.(CVE-2015-8575)

  - The ovl_setattr function in fs/overlayfs/inode.c in the
    Linux kernel through 4.3.3 attempts to merge distinct
    setattr operations, which allows local users to bypass
    intended access restrictions and modify the attributes
    of arbitrary overlay files via a crafted
    application.(CVE-2015-8660)

  - A NULL pointer dereference flaw was found in the Linux
    kernel: the NFSv4.2 migration code improperly
    initialized the kernel structure. A local,
    authenticated user could use this flaw to cause a panic
    of the NFS client (denial of service).(CVE-2015-8746)

  - A race condition flaw was found in the way the Linux
    kernel's SCTP implementation handled sctp_accept()
    during the processing of heartbeat timeout events. A
    remote attacker could use this flaw to prevent further
    connections to be accepted by the SCTP server running
    on the system, resulting in a denial of
    service.(CVE-2015-8767)

  - An infinite-loop flaw was found in the kernel. When a
    local user calls the sys_writev syscall with a
    specially crafted sequence of iov structs, the
    fuse_fill_write_pages kernel function might never
    terminate, instead continuing in a tight loop. This
    process cannot be terminated and requires a
    reboot.(CVE-2015-8785)

  - A NULL-pointer dereference vulnerability was found in
    the Linux kernel's TCP stack, in
    net/netfilter/nf_nat_redirect.c in the
    nf_nat_redirect_ipv4() function. A remote,
    unauthenticated user could exploit this flaw to create
    a system crash (denial of service).(CVE-2015-8787)

  - A use-after-free flaw was found in the CXGB3 kernel
    driver when the network was considered to be congested.
    The kernel incorrectly misinterpreted the congestion as
    an error condition and incorrectly freed or cleaned up
    the socket buffer (skb). When the device then sent the
    skb's queued data, these structures were referenced. A
    local attacker could use this flaw to panic the system
    (denial of service) or, with a local account, escalate
    their privileges.(CVE-2015-8812)

  - 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 ioresources_init function in kernel/resource.c in
    the Linux kernel through 4.7, as used in Android before
    2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak
    permissions for /proc/iomem, which allows local users
    to obtain sensitive information by reading this file,
    aka Android internal bug 28814213 and Qualcomm internal
    bug CR786116. NOTE: the permissions may be intentional
    in most non-Android contexts.(CVE-2015-8944)

  - 'A flaw was found in the Linux kernel's implementation
    of overlayfs. An attacker can leak file resources in
    the system by opening a large file with write
    permissions on a overlay filesystem that is
    insufficient to deal with the size of the write.

  - When unmounting the underlying device, the system is
    unable to free an inode and this will consume
    resources. Repeating this for all available inodes and
    memory will create a denial of service
    situation.(CVE-2015-8953)'

  - The rfcomm_sock_bind function in
    net/bluetooth/rfcomm/sock.c in the Linux kernel before
    4.2 allows local users to obtain sensitive information
    or cause a denial of service (NULL pointer dereference)
    via vectors involving a bind system call on a Bluetooth
    RFCOMM socket.(CVE-2015-8956)

  - A flaw was found in the ext4 subsystem. This
    vulnerability is a use after free vulnerability was
    found in __ext4_journal_stop(). Attackers could abuse
    this to allow any code which attempts to deal with the
    journal failure to be mishandled or not fail at all.
    This could lead to data corruption or
    crashes.(CVE-2015-8961)

  - A flaw was found in the Linux kernel SCSI subsystem,
    which allowed a local user to gain privileges or cause
    a denial of service (memory corruption and system
    crash) by issuing an SG_IO ioctl call while a device
    was being detached.(CVE-2015-8962)

  - Race condition in kernel/events/core.c in the Linux
    kernel before 4.4 allows local users to gain privileges
    or cause a denial of service via use-after-free
    vulnerability by leveraging incorrect handling of an
    swevent data structure during a CPU unplug
    operation.(CVE-2015-8963)

  - The tty_set_termios_ldisc() function in
    'drivers/tty/tty_ldisc.c' in the Linux kernel before
    4.5 allows local users to obtain sensitive information
    from kernel memory by reading a tty data
    structure.(CVE-2015-8964)

  - The lrw_crypt() function in 'crypto/lrw.c' in the Linux
    kernel before 4.5 allows local users to cause a system
    crash and a denial of service by the NULL pointer
    dereference via accept(2) system call for AF_ALG socket
    without calling setkey() first to set a cipher
    key.(CVE-2015-8970)

  - It was found that kernel/events/core.c in the Linux
    kernel mishandles counter grouping, which allows local
    users to gain privileges via a crafted application,
    related to the perf_pmu_register and perf_event_open
    functions.(CVE-2015-9004)

  - A use-after-free flaw was discovered in the Linux
    kernel's tty subsystem, which allows for the disclosure
    of uncontrolled memory location and possible kernel
    panic. The information leak is caused by a race
    condition when attempting to set and read the tty line
    discipline. A local attacker could use the TIOCSETD
    (via tty_set_ldisc ) to switch to a new line discipline
    a concurrent call to a TIOCGETD ioctl performing a read
    on a given tty could then access previously allocated
    memory. Up to 4 bytes could be leaked when querying the
    line discipline or the kernel could panic with a
    NULL-pointer dereference.(CVE-2016-0723)

    kernel allowed local users to gain privileges via
    crafted system calls that trigger mishandling of
    packet_fanout data structures, because of a race
    condition (involving fanout_add and packet_do_bind) that
    leads to a use-after-free, a different vulnerability
    than CVE-2017-6346 (bnc#1064388).

  - CVE-2015-9004: kernel/events/core.c in the Linux kernel
    mishandled counter grouping, which allowed local users
    to gain privileges via a crafted application, related to
    the perf_pmu_register and perf_event_open functions
    (bnc#1037306).

  - CVE-2016-10229: udp.c in the Linux kernel allowed remote
    attackers to execute arbitrary code via UDP traffic that
    triggers an unsafe second checksum calculation during
    execution of a recv system call with the MSG_PEEK flag
    (bnc#1032268).

  - CVE-2016-9604: The handling of keyrings starting with
    '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have
    allowed local users to manipulate privileged keyrings,
    was fixed (bsc#1035576)

  - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds
    Write. Due to a missing bounds check, and the fact that
    parport_ptr integer is static, a 'secure boot' kernel
    command line adversary (can happen due to bootloader
    vulns, e.g. Google Nexus 6's CVE-2016-10277, where due
    to a vulnerability the adversary has partial control
    over the command line) can overflow the parport_nr array
    in the following code, by appending many (>LP_NO)
    'lp=none' arguments to the command line (bnc#1039456).

  - CVE-2017-1000365: The Linux Kernel imposes a size
    restriction on the arguments and environmental strings
    passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the
    size), but did not take the argument and environment
    pointers into account, which allowed attackers to bypass
    this limitation. (bnc#1039354).

  - CVE-2017-1000380: sound/core/timer.c in the Linux kernel
    is vulnerable to a data race in the ALSA /dev/snd/timer
    driver resulting in local users being able to read
    information belonging to other users, i.e.,
    uninitialized memory contents may be disclosed when a
    read and an ioctl happen at the same time (bnc#1044125).

  - CVE-2017-10661: Race condition in fs/timerfd.c in the
    Linux kernel allowed local users to gain privileges or

    operations that leverage improper might_cancel queueing
    (bnc#1053152).

  - CVE-2017-11176: The mq_notify function in the Linux
    kernel did not set the sock pointer to NULL upon entry
    into the retry logic. During a user-space close of a
    Netlink socket, it allowed attackers to cause a denial
    of service (use-after-free) or possibly have unspecified
    other impact (bnc#1048275).

  - CVE-2017-12153: A security flaw was discovered in the
    nl80211_set_rekey_data() function in
    net/wireless/nl80211.c in the Linux kernel This function
    did not check whether the required attributes are
    present in a Netlink request. This request can be issued
    by a user with the CAP_NET_ADMIN capability and may
    result in a NULL pointer dereference and system crash
    (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in
    arch/x86/kvm/vmx.c in the Linux kernel did not ensure
    that the 'CR8-load exiting' and 'CR8-store exiting' L0
    vmcs02 controls exist in cases where L1 omits the 'use
    TPR shadow' vmcs12 control, which allowed KVM L2 guest
    OS users to obtain read and write access to the hardware
    CR8 register (bnc#1058507).

  - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A
    user-controlled buffer is copied into a local buffer of
    constant size using strcpy without a length check which
    can cause a buffer overflow. (bnc#1053148).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)
    allowed reinstallation of the Group Temporal Key (GTK)
    during the group key handshake, allowing an attacker
    within radio range to replay frames from access points
    to clients (bnc#1063667).

  - CVE-2017-14051: An integer overflow in the
    qla2x00_sysfs_write_optrom_ctl function in
    drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel
    allowed local users to cause a denial of service (memory
    corruption and system crash) by leveraging root access
    (bnc#1056588).

    net/ipv4/tcp.c in the Linux kernel allowed local users
    to cause a denial of service (__tcp_select_window
    divide-by-zero error and system crash) by triggering a
    disconnect within a certain tcp_recvmsg code path
    (bnc#1056982).

  - CVE-2017-14140: The move_pages system call in
    mm/migrate.c in the Linux kernel doesn't check the
    effective uid of the target process, enabling a local
    attacker to learn the memory layout of a setuid
    executable despite ASLR (bnc#1057179).

  - CVE-2017-15265: Use-after-free vulnerability in the
    Linux kernel allowed local users to have unspecified
    impact via vectors related to /dev/snd/seq
    (bnc#1062520).

  - CVE-2017-15274: security/keys/keyctl.c in the Linux
    kernel did not consider the case of a NULL payload in
    conjunction with a nonzero length value, which allowed
    local users to cause a denial of service (NULL pointer
    dereference and OOPS) via a crafted add_key or keyctl
    system call, a different vulnerability than
    CVE-2017-12192 (bnc#1045327).

  - CVE-2017-2647: The KEYS subsystem in the Linux kernel
    allowed local users to gain privileges or cause a denial
    of service (NULL pointer dereference and system crash)
    via vectors involving a NULL value for a certain match
    field, related to the keyring_search_iterator function
    in keyring.c (bnc#1030593).

"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 :

  - A buffer overflow was discovered in tpacket_rcv()
    function in the Linux kernel since v4.6-rc1 through
    v4.13. A number of socket-related syscalls can be made
    to set up a configuration when each packet received by
    a network interface can cause writing up to 10 bytes to
    a kernel memory outside of a kernel buffer. This can
    cause unspecified kernel data corruption effects,
    including damage of in-memory and on-disk XFS
    data.(CVE-2017-14497i1/4%0

  - The qmi_wwan_bind function in
    drivers/net/usb/qmi_wwan.c in the Linux kernel through
    4.13.11 allows local users to cause a denial of service
    (divide-by-zero error and system crash) or possibly
    have unspecified other impact via a crafted USB
    device.(CVE-2017-16650i1/4%0

  - A race condition flaw was found in the way the Linux
    kernel's SCTP implementation handled sctp_accept()
    during the processing of heartbeat timeout events. A
    remote attacker could use this flaw to prevent further
    connections to be accepted by the SCTP server running
    on the system, resulting in a denial of
    service.(CVE-2015-8767i1/4%0

  - A race condition flaw was found in the way the Linux
    kernel's KVM subsystem handled PIT (Programmable
    Interval Timer) emulation. A guest user who has access
    to the PIT I/O ports could use this flaw to crash the
    host.(CVE-2014-3611i1/4%0

  - The Linux kernel is vulnerable to a memory leak in the
    drivers/net/wireless/mac80211_hwsim.c:hwsim_new_radio_n
    l() function. An attacker could exploit this to cause a
    potential denial of service.(CVE-2018-8087i1/4%0

  - An integer underflow flaw was found in the way the
    Linux kernel's Stream Control Transmission Protocol
    (SCTP) implementation processed certain COOKIE_ECHO
    packets. By sending a specially crafted SCTP packet, a
    remote attacker could use this flaw to prevent
    legitimate connections to a particular SCTP server
    socket to be made.(CVE-2014-4667i1/4%0

  - The cx231xx_usb_probe function in
    drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux
    kernel through 4.13.11 allows local users to cause a
    denial of service (NULL pointer dereference and system
    crash) or possibly have unspecified other impact via a
    crafted USB device.(CVE-2017-16536i1/4%0

  - The snd_usb_create_streams function in sound/usb/card.c
    in the Linux kernel, before 4.13.6, allows local users
    to cause a denial of service (out-of-bounds read and
    system crash) or possibly have unspecified other impact
    via a crafted USB device.(CVE-2017-16529i1/4%0

  - A flaw was found in the Linux kernel's random number
    generator API. A null pointer dereference in the
    rngapi_reset function may result in denial of service,
    crashing the system.(CVE-2017-15116i1/4%0

  - The __netlink_deliver_tap_skb function in
    net/netlink/af_netlink.c in the Linux kernel, through
    4.14.4, does not restrict observations of Netlink
    messages to a single net namespace, when CONFIG_NLMON
    is enabled. This allows local users to obtain sensitive
    information by leveraging the CAP_NET_ADMIN capability
    to sniff an nlmon interface for all Netlink activity on
    the system.(CVE-2017-17449i1/4%0

  - 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-2015-8955i1/4%0

  - The aac_compat_ioctl function in
    drivers/scsi/aacraid/linit.c in the Linux kernel before
    3.11.8 does not require the CAP_SYS_RAWIO capability,
    which allows local users to bypass intended access
    restrictions via a crafted ioctl call.(CVE-2013-6383i1/4%0

  - Linux kernel before version 4.16-rc7 is vulnerable to a
    null pointer dereference in dccp_write_xmit() function
    in net/dccp/output.c in that allows a local user to
    cause a denial of service by a number of certain
    crafted system calls.(CVE-2018-1130i1/4%0

  - The Linux kernel is vulerable to a use-after-free flaw
    when Transformation User configuration
    interface(CONFIG_XFRM_USER) compile-time configuration
    were enabled. This vulnerability occurs while closing a
    xfrm netlink socket in xfrm_dump_policy_done. A
    user/process could abuse this flaw to potentially
    escalate their privileges on a
    system.(CVE-2017-16939i1/4%0

  - A vulnerability was found in the Linux kernel in
    function rds_inc_info_copy of file net/rds/recv.c. The
    last field 'flags' of object 'minfo' is not
    initialized. This can leak data previously at the flags
    location to userspace.(CVE-2016-5244i1/4%0

  - A flaw was found in the kernel's ACPI interpreter when
    it does not flush the operand cache and causes a kernel
    stack dump. This allows local users to obtain sensitive
    information from kernel memory and bypass the KASLR
    protection mechanism.(CVE-2017-13693i1/4%0

  - It was found that kernel/events/core.c in the Linux
    kernel mishandles counter grouping, which allows local
    users to gain privileges via a crafted application,
    related to the perf_pmu_register and perf_event_open
    functions.(CVE-2015-9004i1/4%0

  - The xfs_bmap_extents_to_btree function in
    fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through
    4.16.3 allows local users to cause a denial of service
    (xfs_bmapi_write NULL pointer dereference) via a
    crafted xfs image.(CVE-2018-10323i1/4%0

  - The lrw_crypt() function in 'crypto/lrw.c' in the Linux
    kernel before 4.5 allows local users to cause a system
    crash and a denial of service by the NULL pointer
    dereference via accept(2) system call for AF_ALG socket
    without calling setkey() first to set a cipher
    key.(CVE-2015-8970i1/4%0

  - The IPv6 fragmentation implementation in the Linux
    kernel does not consider that the nexthdr field may be
    associated with an invalid option, which allows local
    users to cause a denial of service (out-of-bounds read
    and BUG) or possibly have unspecified other impact via
    crafted socket and send system calls. Due to the nature
    of the flaw, privilege escalation cannot be fully ruled
    out, although we believe it is
    unlikely.(CVE-2017-9074i1/4%0
