What is CVE-2015-5254?

Apache ActiveMQ versions prior to 5.13.0 contain a vulnerability that permits remote attackers to execute arbitrary code. This occurs due to inadequate restrictions on the classes that may be serialized within the broker, specifically through a crafted serialized Java Message Service (JMS) ObjectMessage. Exploiting this vulnerability allows attackers to manipulate Java objects and execute malicious code, potentially compromising the security and integrity of the system.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
