Doc Text:
A flaw was found in FreeRDP. The FreeRDP proxy accepts untrusted target TLS certificates when no verification module is configured. A network-positioned attacker who can intercept the proxy's outbound connection can present a self-signed or wrong-hostname certificate to impersonate the RDP target and receive proxied session data. This issue affects FreeRDP from 2.0.0 before 3.32.0.

Description OSIDB Bzimport 2026-10-21 01:03:16 UTC
FreeRDP from 2.0.0 before 3.32.0 contains an improper certificate validation vulnerability in its proxy that accepts untrusted target TLS certificates when no verification module is configured. Network-positioned attackers can intercept the proxy's outbound connection and present a self-signed, wrong-hostname certificate to impersonate the RDP target and receive proxied session data.
