FKIE_CVE-2026-42452

Vulnerability from fkie_nvd - Published: 2026-05-08 23:16 - Updated: 2026-07-25 11:10
Severity
8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.1.0, /users/login issues a temporary JWT (temp_token) for TOTP-enabled accounts. That token carries a pendingTOTP state and should only be valid for the second-factor flow. However, the auth middleware accepts this token on regular authenticated endpoints. This effectively turns 2FA into single-factor (password) for impacted accounts. This issue has been patched in version 2.1.0.

Antes de la versi\u00f3n 2.1.0, /users/login emite un JWT temporal (temp_token) para cuentas con TOTP habilitado. Ese token lleva un estado pendingTOTP y solo deber\u00eda ser v\u00e1lido para el flujo del segundo factor. Sin embargo, el middleware de autenticaci\u00f3n acepta este token en puntos finales autenticados regulares. Esto convierte efectivamente la 2FA en un factor \u00fanico (contrase\u00f1a) para las cuentas afectadas. Este problema ha sido parcheado en la versi\u00f3n 2.1.0."
