Vulnerability Title
Termix has improper certificate validation in Electron desktop client that enables MITM credential/token theft
Source: CVE Program / CVE List V5
Vulnerability Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Starting in version 1.7.0, Termix Desktop (Electron) disables TLS certificate validation, allowing a machine-in-the-middle attacker to intercept and modify HTTPS traffic to the configured Termix server. This can lead to credential theft and JWT/session theft during login and normal use. As of time of publication, no known patched versions are available.
