What it is

Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the handling of the "backend_url" JavaScript link. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.
