CyberRota Analysis
AI-GeneratedFreeRDP versions prior to 3.29.0 are vulnerable due to improper validation of CRLF and control characters in the RDP redirection TargetNetAddress field, which can lead to arbitrary header injection in HTTP proxy CONNECT requests. This critical vulnerability allows a malicious RDP server to manipulate client connections, potentially compromising the integrity of the proxy communication. Organizations using FreeRDP, especially those relying on HTTP proxies for remote desktop connections, should prioritize patching to mitigate this risk.

Original NVD Description
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.
