Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 3.13.9 (Operating System). Affected by this issue is an unknown part of the component Netlink Socket Handler. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is integrity. CVE summarizes:

The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program.

The weakness was disclosed 04/22/2014 by Andy Lutomirski as CVE-2014-0181: Linux network reconfiguration due to incorrect netlink checks as confirmed mailinglist post (oss-sec). The advisory is available at seclists.org. This vulnerability is handled as CVE-2014-0181 since 12/03/2013. The exploitation is known to be easy. Local access is required to approach this attack. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

The vulnerability scanner Nessus provides a plugin with the ID 73957 (Fedora 20 : kernel-3.14.3-200.fc20 (2014-6122)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 167678 (SUSE Enterprise Linux Security update for Linux kernel (SUSE-SU-2015:0652-1)).
