TWiki revision control shell command injection

Added: 04/06/2006
CVE: CVE-2005-2877
BID: 14834
OSVDB: 19403

Background

TWiki is a web-based collaboration platform written in PERL.

Problem

The revision control function in TWiki does not sufficiently check the **rev** parameter before using it in a shell command call. This allows remote attackers to execute arbitrary commands using a **rev** parameter containing shell metacharacters.

Resolution

Apply the patch referenced in CIAC Bulletin P-307.
