In this course, you'll delve into the intricacies of exploiting the Apache Struts s2-045 vulnerability, known for its widespread exploitation and potential to be "worm-able." The course covers affected Struts versions and explains how the vulnerability arises from evaluating the `Content-Type` header during error generation. You'll learn to construct and tweak payloads to detect the vulnerability without executing commands, and how to gain command execution using `curl`.

Through hands-on exercises and video tutorials, you'll gain practical knowledge on how to test for this vulnerability in Struts applications. Detailed explanations of the payload's components, such as Object Graph Navigation Language (OGNL) and the ProcessBuilder class in Java, will equip you with the skills to understand and exploit this critical issue. By the end of the course, you'll be adept at identifying and mitigating the s2-045 vulnerability to secure your Struts applications effectively.
