This repository is a comprehensive exploit library (exphub) containing operational exploit scripts for a wide range of high-profile vulnerabilities affecting popular enterprise software. The structure is organized by product (e.g., drupal/, f5/, fastjson/, jboss/, nexus/, ofbiz/, shiro/, solr/, spring/, struts2/, tomcat/, weblogic/), with each directory containing Python or Java scripts for specific CVEs. The scripts are primarily remote code execution (RCE) exploits, but also include file read, webshell upload, SSRF, and administrative bypasses. Many scripts provide interactive shells or allow arbitrary command execution, and some require authentication. The repository includes both proof-of-concept (POC) and full exploit scripts, with detailed usage instructions embedded in the code and readme files. The attack vector is predominantly network-based, targeting HTTP(S) endpoints, and the scripts are suitable for both vulnerability validation and exploitation. The codebase is mature, with operational exploits for each vulnerability, and is a valuable resource for penetration testers and red teamers.
