Technical details

This vulnerability is an Improper Neutralization of Alternate XSS Syntax (CWE-80), which arises when the application fails to properly sanitize user-supplied input before rendering it in a web context. An unauthenticated attacker with network access to the SCG appliance or application can craft and deliver payloads using alternate XSS syntax that bypass the application's input filters. The attack requires no special privileges or user interaction. Successful exploitation allows arbitrary JavaScript execution in the victim's browser, potentially leading to session hijacking, credential theft, or further network compromise. Patches are available in SCG 5.36.00.16 (appliance) and 5.36.00.00 (application).
