Description

Rapid7 discovered an authentication bypass in the `do_log_on_user()` function in `libunidata.so` that permits a user to authenticate as any Linux user on the target service using a hard-coded username (`:local:`) and a deterministic password. This affects most of the services that UniData ships, and leads directly to shell command execution via the `udadmin` service. Additionally, it allows us to exploit several post-authentication vulnerabilities.

Solution(s)
