Technical details
The vulnerability is an improper encoding or escaping of output (CWE-116) in Dell SCG 5.0 that allows an unauthenticated attacker with network access to inject malicious content. The affected component fails to properly escape or encode user-supplied input before rendering it in responses, enabling stored or reflected cross-site scripting (XSS) or phishing attack vectors. The vulnerability requires no authentication or user interaction for initial exploitation. An attacker can craft requests that bypass output validation filters and inject HTML/JavaScript that executes in the context of users accessing the gateway. Patches are available in SCG 5.0 Appliance version 5.36.00.16 and Application version 5.36.00.00 or later.
