Remediation
Red Hat mitigation
#!/bin/bash mv /usr/share/nagios/html/includes/rss /usr/share/nagios/html/includes/rss.disarmed mv /usr/share/nagios/html/rss-corefeed.php /usr/share/nagios/html/rss-corefeed.php.disarmed mv /usr/share/nagios/html/rss-newsfeed.php /usr/share/nagios/html/rss-newsfeed.php.disarmed This should disable rss from nagios installation and stop affected php code from being executed. Only downside to this would be news widget wont fetch any data from nagios.org rss feeds.
