Vulnerability title: Remote Code Execution In Fitnesse Wiki

CVE: CVE-2014-1216
Vendor: Fitnesse
Product: Wiki
Affected version: v20131110 and earlier
Fixed version: N/A
Reported by: Jerzy Kramarz


The Fitnesse wiki does not validate the syntax of edited pages to validate whether the pages are introducing any extra parameters that could be executed in the context of the application. This vulnerability could be exploited by remote attackers to introduce external commands into the workflow of the application that would execute them.

After creating a new page in the wiki (or editing already existing page) sending a request similar to below would trigger the vulnerability:
