Technical details
A NULL pointer dereference vulnerability exists in the websocket transport handler when processing websocket pings with zero-length payloads. The websocket_reply_pong function passes a nullptr stream to websocket_reply_close, which then triggers an assertion failure in the underlying packet handling code. An unauthenticated attacker controlling a malicious RDP gateway can exploit this with a network request to crash connected clients.
Affected products
- FreeRDP Project FreeRDP before 3.32.0
