Descriptions

The combination of various cryptographic issues in the session management of FortiMail 6.4.0 through 6.4.4 and 6.2.0 through 6.2.6, including the encryption construction of the session cookie, may allow a remote attacker already in possession of a cookie to possibly reveal and alter or forge its content, thereby escalating privileges.

Una combinación de varios problemas criptográficos en la administración de sesiones de FortiMail versiones 6.4.0 hasta 6.4.4 y versiones 6.2.0 hasta 6.2.6, incluyéndo la construcción del cifrado de la cookie de sesión, puede permitir a un atacante remoto que ya esté en posesión de una cookie, a posiblemente revelar y alterar o falsificar su contenido, escalando así los privilegios
