Name of the Vulnerable Software and Affected Versions
FreeRDP versions prior to 3.28.0
Description
FreeRDP treats lines starting with a forward slash in RDP files as raw command-line options, which exposes the entire CLI parser surface to untrusted files. This allows attackers to use malicious RDP files containing options such as
/rdp2tcp, /cert:ignore, or /drive to execute arbitrary commands, bypass certificate validation, or expose local filesystems without user interaction.Recommendations
Update FreeRDP to version 3.28.0 or later.
