Descriptions

The ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a valid network IP address, which allows remote attackers to obtain network information and facilitate other attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0. NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way that is similar to strcpy's role in buffer overflows, in which case this would be a class of implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a security-relevant manner.

La función ip2long en PHP 5.1.4 y anteriores puede validar incorrectamente una cadena de su elección y devolver una dirección IP, la cual permite a atacantes remotos obtener información y facilitar otros ataques, como se demostró usando inyección SQL en la cabecera X-FORWARDED-FOR en index.php en MiniBB 2.0. NOTA: podría discutirse que el funcionamiento ip2long representa un riesgo para los asuntos de seguridad relevantes en la medida que es similar al papel de los strcpy en el desbordamiento de búfer, en cuyo caso esto podría ser un tipo de bug de implementación que requeriría separar los asuntos CVE para cada aplicación PHP que utiliza ip2long en una manera se seguridad relevante.
