Description


Stefan Esser has reported a vulnerability in Trac, which can be exploited by malicious users to disclose sensitive information and potentially compromise a vulnerable system.

The vulnerability is caused due to an input validation error in the "id" parameter when processing an attachment upload and download request. This can be exploited to retrieve any files accessible by the web server, or to upload files to writable directories by supplying arbitrary paths to the parameter.

The vulnerability has been reported in versions 0.8.3 and prior.


Solution:
Update to version 0.8.4 or later.
