Loading vulnerability…
A Java deserialization vulnerability in the Apache BlazeDS library bundled with Adobe ColdFusion allows remote attackers to supply crafted serialized Java data that is deserialized by the application, leading to arbitrary code execution. The issue affects Adobe ColdFusion 2016 Update 3 and earlier, ColdFusion 11 Update 11 and earlier, and ColdFusion 10 Update 22 and earlier. The vulnerable condition resides in ColdFusion’s use of the BlazeDS component, where unsafe deserialization of untrusted input can result in attacker-controlled object instantiation and execution flow.

This repository provides 'ColdFusionPwn', a Java-based exploit tool for CVE-2017-3066, a deserialization vulnerability in Adobe ColdFusion 11 and 12. The tool generates malicious AMF (Action Message Format) payloads using ysoserial gadget chains, which, when deserialized by a vulnerable ColdFusion server, result in arbitrary command execution. The main entry point is 'ColdFusionPwner.java', which takes arguments specifying the exploit technique, ysoserial gadget type, command to execute, and output file for the payload. The repository includes supporting Java classes to craft the payloads in the required format. No hardcoded network endpoints are present, as the tool is designed to generate payloads for delivery to a target server by other means. The structure is typical for a Java Maven project, with a clear separation between exploit logic and supporting classes. The exploit is a proof-of-concept and requires the attacker to deliver the generated payload to a vulnerable ColdFusion server's AMF endpoint.
