Technical details
The vulnerability is a reflected XSS in the visioUrl parameter caused by improper input filtering in app/Common/Req.php. The parameter was URL-decoded after filtering rather than being routed through the URL-sanitizing branch, allowing attribute breakout payloads to bypass sanitization. An unauthenticated attacker can craft a malicious URL containing JavaScript-executing HTML attributes that execute in the victim's browser before authentication is required.
Affected products
