Struts devMode

This course details how attackers can exploit Struts applications running in devMode to gain code execution on the system. It begins by explaining how to detect if devMode is enabled by accessing specific URLs that trigger commands supported by Struts. The course then dives into techniques for gaining code execution using an OGNL interpreter accessed via devMode, including methods to evaluate Java code and execute system commands. Finally, it covers how to leverage these vulnerabilities to bind a shell to a port, providing deeper access to the compromised system.

The course emphasizes the importance of checking for development modes in frameworks and application servers during security testing. Practical examples and step-by-step instructions guide learners through the entire process of exploiting devMode vulnerabilities, from initial detection to gaining a shell on the target system. By the end of this course, learners will have a thorough understanding of how to identify and exploit these weaknesses in Struts applications.
