| Detailed Description |
According to its banner, PHP 5.4.36 is installed on the remote host. It is, therefore, affected by a use-after-free error in the 'process_nested_data' function within 'ext/standard/var_unserializer.re' due to improper handling of duplicate keys within the serialized properties of an object. A remote attacker, using a specially crafted call to the 'unserialize' method, can exploit this flaw to execute arbitrary code on the system.
* Note: This check solely relied on the version number of the remote PHP to assess this vulnerability, so this might be a false positive.
