Hi all, We are proud to announce a new and free Apache Struts2 Web-Hacking challenge. Ever thought about vulnerabilities in frameworks and libraries one is using in its web app? Apache Struts is used in many web apps around the globe. But the vulnerability and the impact is not very known. That's why we have written a "vulnerable" service you can legally mess around with. It is important to keep an eye on such components and dependencies. Try to solve the struts challenge! (Level = Advanced) Read more about the Struts2 problem here: * http://struts.apache.org/2.x/docs/s2-009.html Watch this Hacking-Lab intro movie and get familiar with our vulnerable e-banking service and the challenge host. The exploit string is obfuscated and hidden to make it more interesting for you. * http://media.hacking-lab.com/movies/struts2/ Do you feel like little hands-on experience? No problem, register to our free Hacking Challenge, connect to the lab using VPN and learn more about exploitation and remedy. Get our free HL LiveCD and speed up your connection to the lab. * https://www.hacking-lab.com/events/registerform.html?eventid=199 Mitigation It is strongly recommended to upgrade to Struts 2.3.1.2, which contains the corrected OGNL and XWork library. Vulnerable apps are at high risk (remote code execution). Have a safe day Ivan Buetler
