Description Michael Kaplan 2020-06-19 15:16:09 UTC

Nagios 4.4.5 allows an attacker, who already has administrative access to change the "URL for JSON CGIs" configuration setting, to modify the Alert Histogram and Trends code via crafted versions of the archivejson.cgi, objectjson.cgi, and statusjson.cgi files.
