What it is

Nagios XI versions prior to 5.8.7 using embedded Nagios Core are vulnerable to cross-site scripting (XSS) via the Core UI’s Views URL handling (escape_string()). 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.
