Session-cookie theft via stored product-note script
Published Oct 16, 2025 · Updated Oct 16, 2025
Stored XSS in Sergestec SISTICK 7.2 allows remote authenticated users to steal another user's session cookie through a saved product note. The product-update handler accepts the obs parameter in a POST to /admin/index.php?action=product_update without neutralizing script content before storing and rendering it. Exploitation requires low-privileged access to save the note and passive interaction by an authenticated victim; the documented consequence is disclosure of that victim's session cookie.
