Synopsis
========
Trac may allow remote attackers to upload files, possibly leading to
the execution of arbitrary code.
Background
==========
Trac is a minimalistic web-based project management, wiki and bug
tracking system including a Subversion interface.
Affected packages
=================

Description
===========
Stefan Esser of the Hardened-PHP project discovered that Trac fails to
validate the "id" parameter when uploading attachments to the wiki or
the bug tracking system.
Impact
======
A remote attacker could exploit the vulnerability to upload arbitrary
files to a directory where the webserver has write access to, possibly
leading to the execution of arbitrary code.
Workaround
