PHP wddx extension information disclosure

php-wddx-information-disclosure (32493)

Low Risk

Description:

PHP could allow a remote attacker to obtain sensitive information, caused by an error in the wddx extension serialization handler. A remote attacker could exploit this vulnerability by sending a specially-crafted request with an overly long key_length value to obtain sensitive information.
