Tarek Nakkouch developed and delivered three new features for the rapid7/metasploit-framework repository over two months, focusing on cybersecurity and exploit development. He built a Metasploit auxiliary module targeting the Listmonk Sprig environment variable exposure, enabling authenticated users to extract sensitive data through campaign previews. For Grav CMS, he engineered a remote code execution exploit module that bypasses Twig sandbox restrictions, optimizing payloads with zlib compression and enhancing HTTP handling using Ruby. Additionally, he improved Grav CMS installation detection by implementing strict HTML parsing and robust error handling, resulting in more reliable vulnerability assessments and streamlined security testing workflows.
December 2025 monthly summary for rapid7/metasploit-framework. Delivered Grav CMS coverage with two primary deliverables: SSTI exploit module and installation-detection improvements. Key enhancements include payload optimization via zlib compression before base64, default FORM_NAME, improved HTTP handling with send_request_cgi, and configurable timeouts with HttpClientTimeout. Strengthened Grav fingerprinting through strict HTML parsing, improving installation verification and login form access checks. Implemented robust error handling for zlib and automatic redirect handling to enhance reliability.

October 2025 monthly summary for rapid7/metasploit-framework: Delivered a new auxiliary module to assess Listmonk Sprig env vulnerability exposure, enabling authenticated users with minimal campaign permissions to extract sensitive environment variables via the campaign preview. Implemented robust module controls, target environment options, and parameterization. This work extends the framework's vulnerability assessment capabilities and supports red-team/defense engagements.
