CVE-2024-45394

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-45394
Authenticator is a browser extension that generates two-step verification codes. In versions 7.0.0 and below, encryption keys for user data were stored encrypted at-rest using only AES-256 and the EVP_BytesToKey KDF. Therefore, attackers with a copy of a user's data are able to brute-force the user's encryption key. Users on version 8.0.0 and above are automatically migrated away from the weak encoding on first login. Users should destroy encrypted backups made with versions prior to 8.0.0.

Summary
  • (es) Authenticator es una extensión del navegador que genera códigos de verificación en dos pasos. En las versiones 7.0.0 y anteriores, las claves de cifrado de los datos de los usuarios se almacenaban cifradas en reposo utilizando únicamente AES-256 y el KDF EVP_BytesToKey. Por lo tanto, los atacantes con una copia de los datos de un usuario pueden forzar la clave de cifrado del usuario. Los usuarios de la versión 8.0.0 y posteriores se migran automáticamente de la codificación débil en el primer inicio de sesión. Los usuarios deben destruir las copias de seguridad cifradas realizadas con versiones anteriores a la 8.0.0.
