How the mentioned CVE works:
This CVE exploits an insecure deserialization vulnerability in Adobe ColdFusion. The flaw exists within the handling of serialized objects. An unauthenticated attacker can send a specially crafted HTTP request containing a malicious serialized object to a vulnerable ColdFusion server. When the server deserializes this object, it triggers the execution of arbitrary code on the underlying system. This occurs because the deserialization process does not properly validate or restrict the classes that can be instantiated, allowing an attacker to leverage a gadget chain to achieve remote code execution. The attack requires no user interaction and results in full control of the compromised server.
