Chutton-r7
Calum Hutton developed and iteratively refined a Tomcat partial PUT deserialization exploit module for the rapid7/metasploit-framework repository, focusing on remote code execution through Java deserialization vulnerabilities. His work included expanding platform support to Unix, Linux, and Windows, improving payload upload and validation logic, and enhancing error handling for more reliable exploitation. Calum also authored comprehensive documentation to guide users through setup, testing, and verification, lowering the barrier to adoption. Using Ruby and leveraging the Metasploit Framework, he delivered robust, user-facing features that improved exploit reliability, platform coverage, and maintainability, demonstrating depth in vulnerability research and exploit development.

Mar 1, 20252025-03 Monthly summary for rapid7/metasploit-framework focused on the Tomcat partial PUT deserialization exploit module. In March, delivered iterative improvements to a module capable of exploiting a Java deserialization vulnerability in Tomcat session restoration, with remote command execution via a crafted payload. The work includes platform-configurable options (Unix/Linux/Windows), refined payload upload and deserialization checks, and more robust success criteria. SSL defaults were adjusted to improve compatibility, and the module was validated against CommonsCollections6 to ensure reliability. These changes enhance the user-facing exploit workflow and the framework's vulnerability verification capabilities.
