CVE-2012-6329

Status Candidate

Overview

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.

Red Hat Security Advisory 2013-0685-01
Posted Mar 26, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0685-01 - Perl is a high-level programming language commonly used for system administration utilities and web programming. A heap overflow flaw was found in Perl. If a Perl application allowed user input to control the count argument of the string repeat operator, an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. A denial of service flaw was found in the way Perl's rehashing code implementation, responsible for recalculation of hash keys and redistribution of hash content, handled certain input. If an attacker supplied specially-crafted input to be used as hash keys by a Perl application, it could cause excessive memory consumption.

Foswiki MAKETEXT 1.1.7 / 1.0.10 Code Execution
Posted Feb 19, 2013
Authored by George Clark, Paul Harvey, Crawford Currie, John Lightsey

This advisory alerts you of a potential security issue with your Foswiki installation. A vulnerability has been reported against the core Perl module CPAN:Locale::Maketext, which Foswiki uses to provide translations when {UserInterfaceInternationalization} is enabled in the configuration. Because of this vulnerability it may be possible for a user to invoke arbitrary perl modules on the server through a crafted macro.

Foswiki MAKETEXT Remote Command Execution
Posted Dec 24, 2012
Authored by juan vazquez, Brian Carlson | Site metasploit.com

This Metasploit module exploits a vulnerability in the MAKETEXT Foswiki variable. By using a specially crafted MAKETEXT, a malicious user can execute shell commands since the input is passed to the Perl "eval" command without first being sanitized. The problem is caused by an underlying security issue in the CPAN:Locale::Maketext module. Only Foswiki sites that have user interface localization enabled (UserInterfaceInternationalisation variable set) are vulnerable. If USERNAME and PASSWORD aren't provided, anonymous access will be tried. Also, if the FoswikiPage option isn't provided, the module will try to create a random page on the SandBox space. The modules has been tested successfully on Foswiki 1.1.5 as distributed with the official Foswiki-1.1.5-vmware image.

TWiki MAKETEXT Remote Command Execution
Posted Dec 24, 2012
Authored by juan vazquez, George Clark | Site metasploit.com

This Metasploit module exploits a vulnerability in the MAKETEXT Twiki variable. By using a specially crafted MAKETEXT, a malicious user can execute shell commands since user input is passed to the Perl "eval" command without first being sanitized. The problem is caused by an underlying security issue in the CPAN:Locale::Maketext module. This works in TWiki sites that have user interface localization enabled (UserInterfaceInternationalisation variable set). If USERNAME and PASSWORD aren't provided, anonymous access will be tried. Also, if the 'TwikiPage' option isn't provided, the module will try to create a random page on the SandBox space. The modules has been tested successfully on TWiki 5.1.2 as distributed with the official TWiki-VM-5.1.2-1 virtual machine.
