CVE-2024-25140

https://notcve.org/view.php?id=CVE-2024-25140

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. Una instalación predeterminada de RustDesk 1.2.3 en Windows coloca un certificado WDKTestCert bajo Autoridades de certificación raíz confiables con uso de clave mejorado de firma de código (1.3.6.1.5.5.7.3.3), válido desde 2023 hasta 2033. • https://github.com/rustdesk/rustdesk/discussions/6444 https://news.ycombinator.com/item?id=39256493 https://serverfault.com/questions/837994 • CWE-295: Improper Certificate Validation •
