Date:	06/22/2005
Bugs:	#96572
ID:	200506-21

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

Package	Vulnerable	Unaffected	Architecture(s)
www-apps/trac	< 0.8.4	>= 0.8.4	All supported architectures

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

There is no known workaround at this time.

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/trac-0.8.4"
