WID-SEC-2026-2384 · first 16.07.2026 · updated 29.09.2026 · CVSS 9,6
What it is about
FreeRDP ist eine freie Implementierung des Remote Desktop Protocol (RDP). Ein Angreifer kann mehrere Schwachstellen in FreeRDP ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, Daten zu manipulieren oder einen Denial-of-Service-Zustand auszulösen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Programmcode auszuführen
- Sicherheitsmaßnahmen zu umgehen
- vertrauliche Informationen offenzulegen
- Daten zu manipulieren oder einen Denial-of-Service-Zustand auszulösen
Am I affected?
Affected according to the BSI:
- Amazon Linux 2
- Red Hat Enterprise Linux
- Fedora Linux
- RESF Rocky Linux
- SUSE Linux
- Ubuntu Linux
- Oracle Linux
- Open Source FreeRDP <3.29.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source FreeRDP 3.29.0
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
