If you cannot patch yet, restrict access to the affected scripts if possible and monitor for suspicious activity related to login.pl and debug.pl. Avoid exposing these scripts to untrusted networks. Follow vendor updates closely for an official fix.
Description
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.
