Nagios Log Server versions prior to 1.4.2 are vulnerable to cross-site scripting (XSS) in the Dashboards section when rendering log entries in the Logs table. Untrusted log content was not safely encoded for the output context, allowing attacker-controlled data present in logs to execute script in the victim’s browser within the application origin.
