CVE-2026-64624

HIGH

FreeRDP RDP File Parser Remote Code Execution via CLI Options

Title source: cna
STIX 2.1

Description

FreeRDP before 3.28.0 treats lines beginning with forward slash in RDP files as raw command-line options, exposing the entire CLI parser surface to untrusted files. Attackers can craft malicious RDP files with /rdp2tcp, /cert:ignore, or /drive options to execute arbitrary commands, bypass certificate validation, or expose local filesystems without user interaction.
