Vulnerabilities > CVE-2014-4157 - Permissions, Privileges, and Access Controls vulnerability in Linux Kernel
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
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.
Vulnerable Configurations
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.

An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696i1/4%0 - It was found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we feel it is unlikely.(CVE-2017-15868i1/4%0 - A vulnerability was found in the key management subsystem of the Linux kernel. An update on an uninstantiated key could cause a kernel panic, leading to denial of service (DoS).(CVE-2017-15299i1/4%0 - 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-2015-8956i1/4%0 - 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-2014-4157i1/4%0 - A flaw was found in the Linux kernel's ext4 filesystem code. A stack-out-of-bounds write in ext4_update_inline_data() is possible when mounting and writing to a crafted ext4 image. An attacker could use this to cause a system crash and a denial of service.(CVE-2018-10880i1/4%0 - The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 3.12.1 does not properly validate a certain size value, which allows local users to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via an FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command.(CVE-2013-6380i1/4%0 - Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to an uncaught exception issue. It could occur if an L2 guest was to throw an exception which is not handled by an L1 guest.(CVE-2016-9588i1/4%0 - A flaw was found in the alarm_timer_nsleep() function in kernel/time/alarmtimer.c in the Linux kernel. The ktime_add_safe() function is not used and an integer overflow can happen causing an alarm not to fire if using a large relative timeout.(CVE-2018-13053i1/4%0 - net/llc/sysctl_net_llc.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry.(CVE-2015-2041i1/4%0 - Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in 'mm/mempolicy.c' in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation.(CVE-2017-7616i1/4%0 - The snd_msnd_interrupt function in sound/isa/msnd/msnd_pinnacle.c in the Linux kernel through 4.11.7 allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a 'double fetch' vulnerability.(CVE-2017-9984i1/4%0 - An integer overflow was discovered in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10. This flaw allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access.(CVE-2017-14051i1/4%0 - A use-after-free flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system.(CVE-2014-4654i1/4%0 - An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space.(CVE-2014-9585i1/4%0 - The usbhid_parse function in drivers/hid/usbhid/hid-core.c in the Linux kernel, before 4.13.8, 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-2017-16533i1/4%0 - A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel.
