Doc Text:
A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol (RDP) server can exploit this vulnerability to inject arbitrary headers or requests into an HTTP proxy CONNECT request. This occurs because FreeRDP does not properly validate control characters in the server-controlled RDP redirection TargetNetAddress field, which is then used without filtering. This injection could allow an attacker to manipulate the proxy's behavior or bypass certain network security policies.

Description OSIDB Bzimport 2026-08-01 13:02:50 UTC
FreeRDP before 3.29.0 (affected versions <= 3.28.0) does not validate CRLF and control characters in the server-controlled RDP redirection TargetNetAddress field. This value is copied into the client's ServerHostname and, when the client connects through an HTTP proxy, is written directly into the proxy CONNECT request line and Host header by http_proxy_connect() without filtering. A malicious or compromised RDP server can send a crafted redirection PDU containing embedded control characters to inject arbitrary headers/requests into the HTTP proxy CONNECT request.
