Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-425: Direct Request ('Forced Browsing'), where the web application does not adequately enforce appropriate authorization on all restricted urls, scripts, or files. In Silverstripe/forum, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A number of form actions in the Forum module are directly accessible. A malicious user (e.g. spammer) can use GET requests to create Members and post to forums, bypassing CSRF and anti-spam measures. Additionally, a forum moderator could be tricked into clicking a specially crafted URL, resulting in a topic being moved. Thanks to Michael Strong for discovering.
