Versions of PHP up to 5.4.44 are susceptible to Use-After-Free (UAF) vulnerabilities when processing custom serialized data through the Serializable class interface. Attackers utilize tools like PHPGGC (PHP Generic Gadget Chains) on GitHub to generate a specifically malformed string payload. When the target application runs unserialize($user_input) , the PHP engine frees an object in memory prematurely while maintaining a pointer to it. The attacker then fills that freed memory space with malicious shellcode, tricking the PHP engine into executing it and granting the attacker an interactive system shell. php 5416 exploit github new
