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.


Proof of concept

https://192.168.1.103:2381/gsearch.php.en?prod=%27%3beval%28alert%28%22uppps%22%29%29%3b%27


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.
