"The version of Nagios XI hosted on the remote web server is affected
by multiple vulnerabilities :

  - A privilege escalation vulnerability exists in the
    method used to install RPMs.

  - A privilege escalation vulnerability exists in the
    method used to edit crontab files.

  - Multiple reflective cross-site scripting vulnerabilities
    exist due to the failure to sanitize the query strings
    of GET requests.

  - A stored cross-site scripting vulnerability exists in
    the 'reports/myreports.php' script due to the failure to
    sanitize the report name.

An attacker can leverage the cross-site scripting issues by enticing a
user to follow a malicious URL, causing attacker-specified script code
to run inside the user's browser in the context of the affected site. 
Information harvested this way may aid in launching further attacks.");
