Descriptions

An issue was discovered in Open XDMoD through 7.5.0. An authentication bypass (account takeover) exists due to a weak password reset mechanism. A brute-force attack against an MD5 rid value requires only 600 guesses in the plausible situation where the attacker knows that the victim has started a password-reset process (pass_reset.php, password_reset.php, XDUser.php) in the past few minutes.

Se descubrió un problema en Open XDMoD en la versión 7.5.0. Existe una omisión de autenticación (account takeover) debido a un mecanismo de restablecimiento de contraseña débil. Un ataque por fuerza bruta contra un valor de eliminación MD5 requiere sólo 600 suposiciones en la situación plausible en la que el atacante sabe que la víctima ha iniciado un proceso de restablecimiento de contraseña (pass_reset.php, password_reset.php, XDUser.php) en los últimos minutos.
