Link to public exploit:

Vulnerability description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error in (1) ArrayObject and (2) SPLObjectStorage. when the SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization. A remote attacker can trigger a type confusion error via a crafted string that triggers use of a Hashtable destructor and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
