Descriptions

wp-includes/pluggable.php in WordPress before 3.9.2 rejects invalid CSRF nonces with a different timing depending on which characters in the nonce are incorrect, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force attack.

wp-includes/pluggable.php en WordPress anterior a 3.9.2 rechaza cadenas de caracteres de un sólo uso CSRF inválidos con diferencias de tiempo dependiendo de qué caracteres en la cadena de caracteres de un sólo uso sean incorrectos, lo que facilita a atacantes remotos evadir un mecanismo de protección CSRF a través de un ataque de fuerza bruta.
