application server attack toolkit
Role in this project:Back-end Developer
Back-end DeveloperContributions:1 release, 134 commits, 4 PRs in 3 years 8 months
Contributions summary:Bryan's primary contribution was enhancing the application server attack toolkit by adding support for various versions of JBoss (WildFly) and incorporating functionality to interact with its management interface. This included modifying existing Python scripts for authentication, information retrieval, and deployment, along with adding a new fingerprint to identify a specific JBoss version. Furthermore, the user implemented new deployers, for example, an EJBInvokerServlet and related code, for exploiting vulnerabilities. The commits also involved fixing bugs related to SMB hash retrieval on different operating systems.
