What is CVE-2017-14143?

The getUserzoneCookie function in Kaltura Media Server versions before 13.2.0 utilizes a hardcoded cookie secret for cookie signature validation. This design flaw permits remote attackers to bypass security measures, enabling PHP object injection attacks that can lead to the execution of arbitrary PHP code by sending specially crafted userzone cookies.

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.
