Summary
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.
If a victim opens a maliciously crafted.rdp file, an attacker can silently inject CLI flags to execute arbitrary code, expose local filesystems, or bypass certificate validation. Red Hat severity: Important — CVSS 7.3 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L).
Weakness: CWE-88.

Mitigation checklist
- To mitigate this issue, users should avoid opening RDP files from untrusted or unknown sources. Ensure SELinux remains in enforcing mode. This is the most important existing Red Hat safeguard for this CVE, confining what an exploited FreeRDP process can access.
