New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

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. NOTE: this vulnerability has been mistakenly associated with CVE-2020-1408.
