Detailsinfo

A vulnerability, which was classified as critical, was found in Perl (Programming Language Software). Affected is the function Locale::Maketext. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users, as demonstrated by the TWiki application before 5.1.3, and the Foswiki application 1.0.x through 1.0.10 and 1.1.x through 1.1.6.

The weakness was presented 01/04/2013 as confirmed git commit (GIT Repository). The advisory is available at perl5.git.perl.org. This vulnerability is traded as CVE-2012-6329 since 12/10/2012. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

A public exploit has been developed by Metasploit in Ruby and been published even before and not after the advisory. The exploit is shared for download at securityfocus.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 12 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 72366 (Ubuntu 10.04 LTS / 12.04 LTS / 12.10 : perl vulnerability (USN-2099-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350569 (Amazon Linux Security Advisory for perl: ALAS-2013-177).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at perl5.git.perl.org.

The vulnerability is also documented in the databases at X-Force (80688), Exploit-DB (23579), Tenable (72366), SecurityFocus (BID 56950†) and Vulnerability Center (SBV-48775†).
