CVE-2023-49255

Estado: ModificadaCrítica (9.8)—

The router console is accessible without authentication at "data" field, and while a user needs to be logged in in order to modify the configuration, the session state is shared. If any other user is currently logged in, the anonymous user can execute commands in the context of the authenticated one. If the logged in user has administrative privileges, it is possible to use webadmin service configuration commands to create a new admin user with a chosen password.
