Summary
FreeRDP: RDSTLS server authentication bypass: a credential-less Capabilities PDU is accepted at the auth step (fail-open `resultCode`)
Details

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP server-side RDSTLS in libfreerdp/core/rdstls.c accepts an attacker-supplied RDSTLSTYPECAPABILITIES PDU while rdstlsserverauthenticate is waiting for RDSTLSTYPEAUTHREQ, leaving resultCode at RDSTLSRESULTSUCCESS and allowing a remote unauthenticated client to bypass the RedirectionGuid, username, domain, or password checks. This issue is fixed in version 3.30.0.
