Boundary and Boundary Enterprise (“Boundary”) is vulnerable to session hijacking through TLS certificate tampering. An attacker with privileges to enumerate active or pending sessions, obtain a private key pertaining to a session, and obtain a valid trust on first use (TOFU) token may craft a TLS certificate to hijack an active session and gain access to the underlying service or application.

The product does not validate, or incorrectly validates, a certificate.
