CVE-2017-12544


Intro
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The HP System Management Homepage (SMH) is a web-based interface that consolidates and simplifies the management of 
ProLiant and Integrity servers running Microsoft Windows or Linux, or HP 9000 and HP Integrity servers running HP-UX 
11i. By aggregating data from HP Insight Management Agents and other tools, SMH provides a secure and intuitive 
interface to review in-depth hardware configuration and status data, performance metrics, system thresholds and 
software version control information.


The risk is high because this software is used in HP Windows and Linux servers. Actually there are many banking clients 
affected among other critical industries.

The attacker can trigger this vulnerability without authentication.

There is a JavaScript injection in file gsearch.php.en that affects form parameter prod sent over GET method, exactly 
in this line:

var prodName = '<?php echo $prodName; ?>';

That allows arbitrary javascript client-side execution and XSS attacks because quotes are not escaped, and an attacker 
is able to inject directly JavaScript code with optional embedded HTML entities that are executed and rendered in 
victim's browser.

Fix
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

var prodName = '<?php echo htmlentities($prodName); ?>';

Special thanks to Abelardo Suira for helping me to setup the environment and HPE for their support fixing the 
vulnerability.
