Questions about CVE-2021-25298
What does this mean?
The ip_address parameter passes input to a system command without proper handling, so a semicolon can end the intended command and run other code on the Nagios XI server.Source: fastly.com
Am I affected, and how do I check?
The advisory lists Nagios XI versions 5.5.6 to 5.7.5 and tests 5.7.5, with the issue tied to use of the DigitalOcean configuration wizard. Compare the installed Nagios XI version and check whether that wizard was used.Source: fastly.com
What should I do about it?
The checked facts name no fixed version, so no upgrade target is given. Check the vendor advisory for a fix before relying on any version.Source: fastly.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-01-18, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
The checked facts contain no workaround. The only stated condition is use of the DigitalOcean configuration wizard, and the advisory's guidance beyond that is not in these facts.Source: fastly.com
