SODOLA SL902-SWTGW124AS firmware versions through 200.1.20 contain a weak session identifier generation vulnerability that allows attackers to forge authenticated sessions by computing predictable MD5-based cookies. Attackers who know or guess valid credentials can calculate the session identifier offline and bypass authentication without completing the login flow, gaining unauthorized access to the device.
