Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing Functionality Not Properly Constrained by ACLs
    In applications, particularly web applications, access to functionality is mitigated by the authorization framework, whose job it is to map ACLs to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application or can run queries for data that he is otherwise not supposed to.
  • 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.
  • Directory Indexing
    An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.
  • 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.
  • 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.

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2012-6704, CVE-2016-9793

Eric Dumazet found that a local user with CAP_NET_ADMIN capability
could set a socket's buffer size to be negative, leading to a denial
of service or other security impact. Additionally, in kernel versions
prior to 3.5, any user could do this if sysctl net.core.rmem_max was
changed to a very large value.

CVE-2015-1350 / #770492

Ben Harris reported that local users could remove set-capability
attributes from any file visible to them, allowing a denial of
service.

CVE-2015-8962

Calvin Owens fouund that removing a SCSI device while it was being
accessed through the SCSI generic (sg) driver led to a double- free,
possibly causing a denial of service (crash or memory corruption) or
privilege escalation. This could be exploited by local users with
permision to access a SCSI device node.

CVE-2015-8963

Sasha Levin reported that hot-unplugging a CPU resulted in a
use-after-free by the performance events (perf) subsystem, possibly
causing a denial of service (crash or memory corruption) or privilege
escalation. This could by exploited by any local user.

CVE-2015-8964

It was found that the terminal/serial (tty) subsystem did not reliably
reset the terminal buffer state when the terminal line discipline was
changed. This could allow a local user with access to a terminal
device to read sensitive information from kernel memory.

CVE-2016-7097

Jan Kara found that changing the POSIX ACL of a file never cleared its
set-group-ID flag, which should be done if the user changing it is not
a member of the group-owner. In some cases, this would allow the
user-owner of an executable to gain the privileges of the group-owner.

CVE-2016-7910

Vegard Nossum discovered that a memory allocation failure while
handling a read of /proc/diskstats or /proc/partitions could lead to a
use-after-free, possibly causing a denial of service (crash or memory
corruption) or privilege escalation.

CVE-2016-7911

Dmitry Vyukov reported that a race between ioprio_get() and
ioprio_set() system calls could result in a use-after-free, possibly
causing a denial of service (crash) or leaking sensitive information.

CVE-2016-7915

Benjamin Tissoires found that HID devices could trigger an out-of-
bounds memory access in the HID core. A physically present user could
possibly use this for denial of service (crash) or to leak sensitive
information.

CVE-2016-8399

Qidan He reported that the IPv4 ping socket implementation did not
validate the length of packets to be sent. A user with permisson to
use ping sockets could cause an out-of-bounds read, possibly resulting
in a denial of service or information leak. However, on Debian systems
no users have permission to create ping sockets by default.

CVE-2016-8633

Eyal Itkin reported that the IP-over-Firewire driver (firewire-net)
did not validate the offset or length in link-layer fragmentation
headers. This allowed a remote system connected by Firewire to write
to memory after a packet buffer, leading to a denial of service
(crash) or remote code execution.

CVE-2016-8645

Marco Grassi reported that if a socket filter (BPF program) attached
to a TCP socket truncates or removes the TCP header, this could cause
a denial of service (crash). This was exploitable by any local user.

CVE-2016-8655

Philip Pettersson found that the implementation of packet sockets
(AF_PACKET family) had a race condition between enabling a transmit
ring buffer and changing the version of buffers used, which could
result in a use-after-free. A local user with the CAP_NET_ADMIN
capability could exploit this for privilege escalation.

CVE-2016-9178

Al Viro found that a failure to read data from user memory might lead
to a information leak on the x86 architecture (amd64 or i386).

CVE-2016-9555

Andrey Konovalov reported that the SCTP implementation does not
validate 'out of the blue' packet chunk lengths early enough. A remote
system able could use this to cause a denial of service (crash) or
other security impact for systems using SCTP.

CVE-2016-9576, CVE-2016-10088

Dmitry Vyukov reported that using splice() with the SCSI generic
driver led to kernel memory corruption. Local users with permision to
access a SCSI device node could exploit this for privilege escalation.

CVE-2016-9756

Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or
i386) did not correctly handle the failure of certain instructions
that require software emulation on older processors. This could be
exploited by guest systems to leak sensitive information or for denial
of service (log spam).

CVE-2016-9794

Baozeng Ding reported a race condition in the ALSA (sound) subsystem
that could result in a use-after-free. Local users with access to a
PCM sound device could exploit this for denial of service (crash or
memory corruption) or other security impact.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.84-1. This version also includes bug fixes from upstream version
3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
Finally, this version adds the option to mitigate security issues in
the performance events (perf) subsystem by disabling use by
unprivileged users. This can be done by setting sysctl
kernel.perf_event_paranoid=3.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.39-1 which will be included in the next point release (8.6).

    descriptionFrom Red Hat Security Advisory 2017:1842 : 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) : * An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. (CVE-2016-10200, Important) * A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges. (CVE-2017-2647, Important) * It was found that the NFSv4 server in the Linux kernel did not properly validate layout type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote attacker could use this flaw to soft-lockup the system and thus cause denial of service. (CVE-2017-8797, Important) This update also fixes multiple Moderate and Low impact security issues : * CVE-2015-8839, CVE-2015-8970, CVE-2016-9576, CVE-2016-7042, CVE-2016-7097, CVE-2016-8645, CVE-2016-9576, CVE-2016-9588, CVE-2016-9806, CVE-2016-10088, CVE-2016-10147, CVE-2017-2596, CVE-2017-2671, CVE-2017-5970, CVE-2017-6001, CVE-2017-6951, CVE-2017-7187, CVE-2017-7616, CVE-2017-7889, CVE-2017-8890, CVE-2017-9074, CVE-2017-8890, CVE-2017-9075, CVE-2017-8890, CVE-2017-9076, CVE-2017-8890, CVE-2017-9077, CVE-2017-9242, CVE-2014-7970, CVE-2014-7975, CVE-2016-6213, CVE-2016-9604, CVE-2016-9685 Documentation for these issues is available from the Release Notes document linked from the References section. Red Hat would like to thank Igor Redko (Virtuozzo) and Andrey Ryabinin (Virtuozzo) for reporting CVE-2017-2647; Igor Redko (Virtuozzo) and Vasily Averin (Virtuozzo) for reporting CVE-2015-8970; Marco Grassi for reporting CVE-2016-8645; and Dmitry Vyukov (Google Inc.) for reporting CVE-2017-2596. The CVE-2016-7042 issue was discovered by Ondrej Kozina (Red Hat); the CVE-2016-7097 issue was discovered by Andreas Gruenbacher (Red Hat) and Jan Kara (SUSE); the CVE-2016-6213 and CVE-2016-9685 issues were discovered by Qian Cai (Red Hat); and the CVE-2016-9604 issue was discovered by David Howells (Red Hat).

"From Red Hat Security Advisory 2017:1842 :

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) :

* An use-after-free flaw was found in the Linux kernel which enables a
race condition in the L2TPv3 IP Encapsulation feature. A local user
could use this flaw to escalate their privileges or crash the system.
(CVE-2016-10200, Important)

* A flaw was found that can be triggered in keyring_search_iterator in
keyring.c if type->match is NULL. A local user could use this flaw to
crash the system or, potentially, escalate their privileges.
(CVE-2017-2647, Important)

* It was found that the NFSv4 server in the Linux kernel did not
properly validate layout type when processing NFSv4 pNFS LAYOUTGET and
GETDEVICEINFO operands. A remote attacker could use this flaw to
soft-lockup the system and thus cause denial of service.
(CVE-2017-8797, Important)

This update also fixes multiple Moderate and Low impact security
issues :

* CVE-2015-8839, CVE-2015-8970, CVE-2016-9576, CVE-2016-7042,
CVE-2016-7097, CVE-2016-8645, CVE-2016-9576, CVE-2016-9588,

    descriptionSecurity Fix(es) : - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation- based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate) - A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table). (CVE-2016-2069, Moderate) - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel

    descriptionIt was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-1000251) It was discovered that the asynchronous I/O (aio) subsystem of the Linux kernel did not properly set permissions on aio memory mappings in some situations. An attacker could use this to more easily exploit other vulnerabilities. (CVE-2016-10044) Baozeng Ding and Andrey Konovalov discovered a race condition in the L2TPv3 IP Encapsulation implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-10200) Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges. (CVE-2016-7097) Sergej Schumilo, Ralf Spenneberg, and Hendrik Schwartke discovered that the key management subsystem in the Linux kernel did not properly allocate memory in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-8650) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084) It was discovered that an information leak existed in __get_user_asm_ex() in the Linux kernel. A local attacker could use this to expose sensitive information. (CVE-2016-9178) CAI Qian discovered that the sysctl implementation in the Linux kernel did not properly perform reference counting in some situations. An unprivileged attacker could use this to cause a denial of service (system hang). (CVE-2016-9191) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. (CVE-2016-9604) It was discovered that an integer overflow existed in the trace subsystem of the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2016-9754) Andrey Konovalov discovered that the IPv4 implementation in the Linux kernel did not properly handle invalid IP options in some situations. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2017-5970) Dmitry Vyukov discovered that the Linux kernel did not properly handle TCP packets with the URG flag. A remote attacker could use this to cause a denial of service. (CVE-2017-6214) It was discovered that a race condition existed in the AF_PACKET handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-6346) It was discovered that the keyring implementation in the Linux kernel did not properly restrict searches for dead keys. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-6951) Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux kernel contained a stack-based buffer overflow. A local attacker with access to an sg device could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7187) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) It was discovered that a buffer overflow existed in the Broadcom FullMAC WLAN driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7541). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate) * A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).

    descriptionThe SUSE Linux Enterprise 11 SP2 LTSS kernel was updated to receive various security and bugfixes. This is the last planned LTSS kernel update for the SUSE Linux Enterprise Server 11 SP2 LTSS. The following security bugs were fixed : - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2004-0230: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#969340). -

    descriptionAn update for kernel-rt 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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es) : * An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. (CVE-2016-10200, Important) * A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges.

    NASL idORACLELINUX_ELSA-2017-0817.NASL
    descriptionFrom Red Hat Security Advisory 2017:0817 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate) * A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table). (CVE-2016-2069, Moderate) * A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel

    descriptionThe SUSE Linux Enterprise 12 kernel was updated to 3.12.67 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bsc#1004517). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bsc#995968). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed 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 (bnc#1003925). - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for man-in-the-middle attackers to hijack TCP sessions via a blind in-window attack (bnc#989152). - CVE-2016-6130: Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by changing a certain length value, aka a
