SonicWall’s GMS is a central policy management solution for managing your security appliances. Among other hilarious bugs, it included backdoor accounts UT000000000000, UT123456789100, UT123456789200, and UT123456789300. Each of these has a default password of “password,” and the first just happens to have the authority to add new user accounts!
