Introduction:  
-------------  
Compass Security AG [3] discovered a security flaws in the i-doit CMDB  
web application [2], which allows execution of malicious code.  
  
  
Vulnerable:  
-----------  
i-doit Pro 1.2.4 and likely all prior versions including i-doit Open.  
  
  
Description:  
------------  
The i-doit web application does not properly encode output of user data  
in at least one place. Exploiting this vulnerability leads to reflected  
cross-site scripting (XSS) and allows execution of JavaScript code in  
the context of the user's session, e.g. to impersonate logged-in i-doit  
CMDB users.  
  
The vulnerable resource is the 'call' parameter:  
/?ajax=1&objID=1753&call=');}</script><script>alert('XSS')</script>  
  
  
Remediation:  
------------  
Upgrade to i-doit Pro 1.2.4. The 'Open' flavour will not receive patches  
in its current branch any longer, as explained by the vendor.
