`Product: HPE System Management Homepage  
Versions: 7.6.0.11 and minor versions  
Vulnerability: JavaScript Injection in file gsearch.php, parameter prod  
OWASP TOP 10: A1 Injection  
Type: Javascript Injection  
Impact: Allows an attacker to perform an XSS (Cross-Site Scripting) attack, execute arbitrary JavaScript client-side, steal admin credentials, etc  
  
Access Vector: Adjacent Networks  
Access Complexity: Low  
Authentication: None  
  
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); ?>';
