"The LogAnalyzer install hosted on the remote web server is affected by
a cross-site scripting vulnerability due to a failure to properly
sanitize user input to the 'filter' parameter of the 'index.php'
script. An attacker can exploit this issue to inject arbitrary HTML
and script code into a user's browser to be executed within the
security context of the affected site.

The application is reportedly also affected by a SQL injection
vulnerability, an arbitrary file read vulnerability, and additional
cross-site scripting vulnerabilities; however, Nessus has not tested
for these additional vulnerabilities.");
