Detailsinfo

A vulnerability classified as problematic has been found in GNOME gnome-remote-desktop (affected version not known). Affected is some unknown functionality of the component Session Agent Handler. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

A flaw was found in the gnome-remote-desktop package. The gnome-remote-desktop system daemon performs inadequate validation of session agents using D-Bus methods related to transitioning a client connection from the login screen to the user session. As a result, the system RDP TLS certificate and key can be exposed to unauthorized users. This flaw allows a malicious user on the system to take control of the RDP client connection during the login screen-to-user session transition.

I encountered this vulnerability back in 2022, when I found out that a bad actor with local access to my machines and systems had installed VMs (Ubuntu, Kali Linux) via Parallel Desktop and was running them for years.
