Technical details

A stored cross-site scripting (XSS) vulnerability exists in Cotonti Siena versions 0.9.26 and earlier. The vulnerability is located in 'pfs.main.php', where the 'ntitle' parameter is processed through a 'TXT' filter that fails to properly escape HTML tags before storing them in the database. An authenticated attacker with PFS access can inject arbitrary JavaScript by creating a folder with a malicious title. The payload executes when any user, including administrators, views the folder listing. While a sanitization mechanism exists in the codebase, it was reportedly found to be commented out in affected versions. No official patch has been released as of the disclosure date.
