CVE-2015-7450 is a remote code execution vulnerability affecting serialized-object interfaces in multiple IBM products that incorporate vulnerable Apache Commons Collections functionality. The issue arises from unsafe deserialization of attacker-controlled Java serialized objects, specifically gadget chains involving the Apache Commons Collections InvokerTransformer class. When a vulnerable interface accepts crafted serialized input and deserializes it without adequate validation or filtering, attacker-controlled method invocation can be triggered during object reconstruction, leading to arbitrary command or Java code execution. The vulnerability was notably associated with IBM WebSphere Application Server SOAP deserialization exposure and also affected other IBM analytics, business, cognitive, infrastructure, mobile, social, portal, forms, notes, and domino products that bundled or depended on the vulnerable library and exposed deserialization paths.

This repository contains a single Metasploit module targeting IBM WebSphere Application Server 7.0.0.0 on Windows. The exploit leverages CVE-2015-7450, a Java deserialization vulnerability in the Apache Commons Collections library, to achieve unauthenticated remote code execution via a crafted SOAP request. The module constructs a malicious serialized Java object (CommonsCollections1 gadget) containing a PowerShell payload, which is delivered to the target's SOAP endpoint (default path '/' on port 8880, SSL enabled). Upon successful exploitation, arbitrary PowerShell commands can be executed on the target system. The code is structured as a typical Metasploit exploit module, using the HttpClient and Powershell mixins, and is operational with a customizable payload. No authentication is required, and the exploit is network-based. The repository is a single Ruby file, following Metasploit conventions.
