(Trac: File upload vulnerability)
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.
References:
http://www.hardened-php.net/advisory-012005.php
Solution:
All Trac users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/trac-0.8.4"
Risk factor : Medium
