GestSup before 3.2.61 Stored XSS via Email Body in LOGIN IMAP Connector
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
GestSup versions before 3.2.61 fail to properly sanitize HTML email bodies in the IMAP LOGIN connector, allowing unauthenticated attackers to store arbitrary JavaScript in ticket descriptions and replies. Attackers can send emails to the monitored mailbox containing script tags and event handlers that execute in technician browsers, enabling ticket data theft and unauthorized actions.
