Description
HotGo through 2.15.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to choose the SMS login verification code by supplying the Code field to /admin/sms/send. Attackers who know a user's mobile number can set a known code and sign in through /admin/site/mobileLogin to take over accounts, including administrators.
