Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    descriptionThe openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841). - CVE-2018-14625: An attacker might have bene able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients (bnc#1106615). - CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bsc#1120743). - CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946). - CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714). - CVE-2018-18397: The userfaultfd implementation mishandled access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c (bnc#1117656). - CVE-2018-12232: In net/socket.c there was a race condition between fchownat and close in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr functions. fchownat did not increment the file descriptor reference count, which allowed close to set the socket to NULL during fchownat

"The openSUSE Leap 15.0 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed :

  - CVE-2018-19407: The vcpu_scan_ioapic function in
    arch/x86/kvm/x86.c allowed local users to cause a denial
    of service (NULL pointer dereference and BUG) via
    crafted system calls that reach a situation where ioapic
    is uninitialized (bnc#1116841).

  - CVE-2018-14625: An attacker might have bene able to have
    an uncontrolled read to kernel-memory from within a vm
    guest. A race condition between connect() and close()
    function may allow an attacker using the AF_VSOCK
    protocol to gather a 4 byte information leak or possibly
    intercept or corrupt AF_VSOCK messages destined to other
    clients (bnc#1106615).

  - CVE-2018-19985: The function hso_probe read if_num from
    the USB device (as an u8) and used it without a length
    check to index an array, resulting in an OOB memory read
    in hso_probe or hso_get_config_data that could be used
    by local attackers (bsc#1120743).

  - CVE-2018-16884: NFS41+ shares mounted in different
    network namespaces at the same time can make
    bc_svc_process() use wrong back-channel IDs and cause a
    use-after-free vulnerability. Thus a malicious container
    user can cause a host kernel memory corruption and a
    system panic. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out (bnc#1119946).

  - CVE-2018-20169: The USB subsystem mishandled size checks
    during the reading of an extra descriptor, related to
    __usb_get_extra_descriptor in drivers/usb/core/usb.c
    (bnc#1119714).

  - CVE-2018-18397: The userfaultfd implementation
    mishandled access control for certain UFFDIO_ ioctl
    calls, as demonstrated by allowing local users to write
    data into holes in a tmpfs file (if the user has
    read-only access to that file, and that file contains
    holes), related to fs/userfaultfd.c and mm/userfaultfd.c
    (bnc#1117656).

  - CVE-2018-12232: In net/socket.c there was a race
    condition between fchownat and close in cases where they
    target the same socket file descriptor, related to the
    sock_close and sockfs_setattr functions. fchownat did
    not increment the file descriptor reference count, which
    allowed close to set the socket to NULL during
    fchownat's execution, leading to a NULL pointer
    dereference and system crash (bnc#1097593).

  - CVE-2018-9568: In sk_clone_lock of sock.c, there is a
    possible memory corruption due to type confusion. This
    could lead to local escalation of privilege with no
    additional execution privileges needed. User interaction
    is not needed for exploitation. (bnc#1118319).

  - CVE-2018-16862: A security flaw was found in the way
    that the cleancache subsystem clears an inode after the
    final file truncation (removal). The new file created
    with the same inode may contain leftover pages from
    cleancache and the old file data instead of the new one
    (bnc#1117186).

  - CVE-2018-19854: An issue was discovered in the
    crypto_report_one() and related functions in
    crypto/crypto_user.c (the crypto user configuration API)
    do not fully initialize structures that are copied to
    userspace, potentially leaking sensitive memory to user
    programs. NOTE: this is a CVE-2013-2547 regression but
    with easier exploitability because the attacker did not
    need a capability (however, the system must have the
    CONFIG_CRYPTO_USER kconfig option) (bnc#1118428).

  - CVE-2018-19824: A local user could exploit a
    use-after-free in the ALSA driver by supplying a
    malicious USB Sound device (with zero interfaces) that
    is mishandled in usb_audio_probe in sound/usb/card.c
    (bnc#1118152).

    NASL idSUSE_SU-2019-0439-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743). CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946). CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714). CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319). CVE-2018-16862: A security flaw was found in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186). CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152). CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769). CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025). CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. (bnc#1108498). CVE-2019-3459, CVE-2019-3460: The Blutooth stack suffered from two remote information leak vulnerabilities in the code that handles incoming L2cap configuration packets (bsc#1120758). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe SUSE Linux Enterprise 12 SP4 kernel for Azure was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic was uninitialized (bnc#1116841). CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946). CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714). CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1118319). CVE-2018-16862: A security flaw was found in the way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186). CVE-2018-14625: A flaw was found where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients (bnc#1106615). CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743). CVE-2018-12232: In net/socket.c there is a race condition between fchownat and close in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr functions. fchownat did not increment the file descriptor reference count, which allowed close to set the socket to NULL during fchownat

    descriptionAccording 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 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-2015-8374i1/4%0 - crypto/pcrypt.c in the Linux kernel, before 4.14.13, mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2017-18075i1/4%0 - An elevation of privilege vulnerability in the Qualcomm Wi-Fi driver could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as High because it first requires compromising a privileged process. Product: Android. Versions: N/A. Android ID: A-32835279. References: QC-CR#1096945.(CVE-2017-0523i1/4%0 - The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.10.14 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

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.(CVE-2018-18710) - A flaw was found in mmap in the Linux kernel allowing the process to map a null page. This allows attackers to abuse this mechanism to turn null pointer dereferences into workable exploits.(CVE-2019-9213) - The Linux kernel does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.(CVE-2018-1118) - It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.(CVE-2018-10902) - A flaw was discovered in the Linux kernel
