Summary
Cotonti Siena 0.9.26 and earlier contains a stored cross-site scripting vulnerability that allows authenticated users with PFS access to inject arbitrary script payloads by supplying malicious HTML in the ntitle parameter processed through the TXT filter in pfs.main.php. Attackers can create a folder with a crafted title containing script tags that are stored unescaped in the database and execute in the browser of any user who views the folder listing, including administrators.
Risk Assessment
The risk for the organization includes session theft, administrator account takeover, and unauthorized actions performed in the victim's context, potentially leading to data leakage or system integrity compromise.
Recommendation
Immediately update Cotonti Siena to a version later than 0.9.26 or apply a security patch that properly escapes input in the ntitle parameter before storing it in the database.
