Critical (9.2). EPSS 0.5% chance of exploitation in the next 30 days.

Storage Concentrator (SC & SCVM) is vulnerable to SQL injection through cookie values processed by the login.pl and debug.pl scripts. The cookie value is incorporated directly into database queries without adequate sanitization, allowing an unauthenticated remote attacker to manipulate those queries and extract sensitive information from the underlying database, including session tokens, password hashes, and stored secret keys.
