Description

A flaw was found in FreeRDP. An unauthenticated remote attacker could bypass the server-side authentication in the RDSTLS (Remote Desktop Services Transport Layer Security) handshake. By sending a Capabilities PDU instead of the expected Authentication Request PDU, the server incorrectly processes the request, leading to a successful authentication without validating any credentials. This allows the attacker to gain unauthorized access to a session.
