Summary
BeyondTrust Privileged Remote Access (PRA) versions 22.2.x to 22.4.x are vulnerable to a local authentication bypass. Attackers can exploit a flawed secret verification process in the BYOT shell jump sessions, allowing unauthorized access to jump items by guessing only the first character of the secret.
