This fixes the following issue:
The check_mk application is susceptible to reflected XSS attacks. This is mainly the result of inproper output encoding. Reflected XSS can be triggered by sending a malicious URL to a user of the check_mk application. Once the XSS attack is triggered, the attacker has access to the full check_mk (and nagios) application with the access rights of the logged in victim.
The fix applies to the function:
htmllib.py: render_status_icons() actions.py: ajax_action()
