Descriptions
The secureCompare method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.13 and earlier, when used with PHP before 5.6, allows attackers to conduct session fixation attacks or possibly bypass authentication by leveraging missing character conversions before an XOR operation.
El método secureCompare en lib/SimpleSAML/Utils/Crypto.php en SimpleSAMLphp 1.14.13 y anteriores, al usarse con PHP en versiones anteriores a la 5.6, permite que los atacantes lleven a cabo ataques de fijación de sesión o que, posiblemente, omitan la autenticación aprovechando las conversiones de caracteres que faltan antes de una operación XOR.
