# Exploit Title: Privilege Escalation in RedaxScript 2.1.0 # Date: 11-05-2014 # Exploit Author: shyamkumar somana # Vendor Homepage: http://redaxscript.com/ # Version: 2.1.0 # Tested on: Windows 8 #Privilege Escalation in RedaxScript 2.1.0 RedaxScript 2.1.0 suffers from a privilege Escalation vulnerability. The issue occurs because the application fails to properly implement access controls. The application also fails to perform proper sanity checks on the user supplied input before processing it. These two flaws led to a vertical privilege escalation. This can be achieved by a simply tampering the parameter values. An attacker can exploit this issue to gain elevated privileges to the application. *Steps to reproduce the instance:* · login as a non admin user · Go to account and update the account. · intercept the request and add “*groups[]=1*” to the post data and submit the request · Log out of the application and log in again. You can now browse the application with admin privileges. This vulnerability was addressed in the following commit. https://github.com/redaxmedia/redaxscript/commit/bfe146f98aedb9d169ae092b49991ed1b3bc0860?diff=unified *Timeline*: 09-26-2014: Issue identified 09-27-2014: Discussion with the vendor 10-27-2014: Issue confirmed 11-05-2014: Patch released.
