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.

"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 flaw was found in the USB-MIDI Linux kernel driver: a
    double-free error could be triggered for the 'umidi'
    object. An attacker with physical access to the system
    could use this flaw to escalate their
    privileges.(CVE-2016-2384i1/4%0

  - A vulnerability was found in Linux kernel. There is an
    information leak in file 'sound/core/timer.c' of the
    latest mainline Linux kernel, the stack object
    aEURoetreadaEUR has a total size of 32 bytes. It contains a
    8-bytes padding, which is not initialized but sent to
    user via copy_to_user(), resulting a kernel
    leak.(CVE-2016-4569i1/4%0

  - The dgram_recvmsg function in net/ieee802154/dgram.c in
    the Linux kernel before 3.12.4 updates a certain length
    value without ensuring that an associated data
    structure has been initialized, which allows local
    users to obtain sensitive information from kernel stack
    memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg
    system call.(CVE-2013-7281i1/4%0

  - The tcp_v6_syn_recv_sock function in
    net/ipv6/tcp_ipv6.c in the Linux kernel through 4.14.11
    allows attackers to cause a denial of service (slab
    out-of-bounds write) or possibly have unspecified other
    impact via vectors involving TLS.(CVE-2018-5703i1/4%0

  - An issue was discovered in the fd_locked_ioctl function
    in drivers/block/floppy.c in the Linux kernel. 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-2018-7755i1/4%0

  - The usbnet_generic_cdc_bind function in
    drivers/net/usb/cdc_ether.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-2017-16649i1/4%0

  - Heap-based buffer overflow in the wcnss_wlan_write
    function in drivers/net/wireless/wcnss/wcnss_wlan.c in
    the wcnss_wlan device 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 cause a denial of service or
    possibly have unspecified other impact by writing to
    /dev/wcnss_wlan with an unexpected amount of
    data.(CVE-2016-5342i1/4%0

  - drivers/media/usb/dvb-usb/dib0700_devices.c in the
    Linux kernel through 4.13.11 allows local users to
    cause a denial of service (BUG and system crash) or
    possibly have unspecified other impact via a crafted
    USB device.(CVE-2017-16646i1/4%0

  - A flaw was found in the TIPC networking subsystem which
    could allow for memory corruption and possible
    privilege escalation. The flaw involves a system with
    an unusually low MTU (60) on networking devices
    configured as bearers for the TIPC protocol. An
    attacker could create a packet which will overwrite
    memory outside of allocated space and allow for
    privilege escalation.(CVE-2016-8632i1/4%0

  - An issue was discovered in the XFS filesystem in
    fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel. A
    denial of service due to the NULL pointer dereference
    can occur for a corrupted xfs image upon encountering
    an inode that is in extent format, but has more extents
    than fit in the inode fork.(CVE-2018-13095i1/4%0

  - Linux kernel built with the KVM visualization support
    (CONFIG_KVM), with nested visualization (nVMX) feature
    enabled (nested=1), is vulnerable to a crash due to
    disabled external interrupts. As L2 guest could access
    (r/w) hardware CR8 register of the host(L0). In a
    nested visualization setup, L2 guest user could use
    this flaw to potentially crash the host(L0) resulting
    in DoS.(CVE-2017-12154i1/4%0

  - The do_double_fault function in arch/x86/kernel/traps.c
    in the Linux kernel through 3.17.4 does not properly
    handle faults associated with the Stack Segment (SS)
    segment register, which allows local users to cause a
    denial of service (panic) via a modify_ldt system call,
    as demonstrated by sigreturn_32 in the
    linux-clock-tests test suite.(CVE-2014-9090i1/4%0

  - A race condition flaw was found in the way the Linux
    kernel's mac80211 subsystem implementation handled
    synchronization between TX and STA wake-up code paths.
    A remote attacker could use this flaw to crash the
    system.(CVE-2014-2706i1/4%0

  - The snd_seq_ioctl_remove_events function in
    sound/core/seq/seq_clientmgr.c in the Linux kernel
    before 4.4.1 does not verify FIFO assignment before
    proceeding with FIFO clearing, which allows local users
    to cause a denial of service (NULL pointer dereference
    and OOPS) via a crafted ioctl call.(CVE-2016-2543i1/4%0

  - 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-2016-2187i1/4%0

  - An integer overflow flaw was found in the Linux
    kernel's create_elf_tables() function. An unprivileged
    local user with access to SUID (or otherwise
    privileged) binary could use this flaw to escalate
    their privileges on the system.(CVE-2018-14634i1/4%0

  - A use-after-free flaw was found in the Netlink
    functionality of the Linux kernel networking subsystem.
    Due to the insufficient cleanup in the mq_notify
    function, a local attacker could potentially use this
    flaw to escalate their privileges on the
    system.(CVE-2017-11176i1/4%0

  - Array index error in the aio_read_events_ring function
    in fs/aio.c in the Linux kernel through 3.15.1 allows
    local users to obtain sensitive information from kernel
    memory via a large head value.(CVE-2014-0206i1/4%0

  - arch/arm/kernel/sys_oabi-compat.c in the Linux kernel
    before 4.4 allows local users to gain privileges via a
    crafted (1) F_OFD_GETLK, (2) F_OFD_SETLK, or (3)
    F_OFD_SETLKW command in an fcntl64 system
    call.(CVE-2015-8966i1/4%0

  - An issue was discovered in the Linux kernel through
    4.17.2. The filter parsing in
    kernel/trace/trace_events_filter.c could be called with
    no filter, which is an N=0 case when it expected at
    least one line to have been read, thus making the N-1
    index invalid. This allows attackers to cause a denial
    of service (slab out-of-bounds write) or possibly have
    unspecified other impact via crafted perf_event_open
    and mmap system calls.(CVE-2018-12714i1/4%0
