Background

Trac is a minimalistic web-based project management, wiki and bug tracking system including a Subversion interface.

Description

Christophe Truc discovered that Trac fails to properly sanitize input passed in the URL.

Impact

A remote attacker could exploit this to inject and execute malicious script code or to steal cookie-based authentication credentials, potentially compromising the victim's browser.

3.  Resolution Information

Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
