Alert meAnalysisAI
A default installation of RustDesk 1.2.3 on Windows places a WDKTestCert certificate under Trusted Root Certification Authorities with Enhanced Key Usage of Code Signing (1.3.6.1.5.5.7.3.3), valid. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Apply vendor patches when available. Implement network segmentation and monitoring as interim mitigations.

Technical ContextAI · show details
This vulnerability is classified under CWE-295. A default installation of RustDesk 1.2.3 on Windows places a WDKTestCert certificate under Trusted Root Certification Authorities with Enhanced Key Usage of Code Signing (1.3.6.1.5.5.7.3.3), valid from 2023 until 2033. This is potentially unwanted, e.g., because there is no public documentation of security measures for the private key, and arbitrary software could be signed if the private key were to be compromised. NOTE: the vendor's position is "we do not have EV cert, so we use test cert as a workaround." Insertion into Trusted Root Certification Authorities was the originally intended behavior, and the UI ensured that the certificate installation step (checked by default) was visible to the user before proceeding with the product installation. Affected products include: Rustdesk.
