medium Nessus Plugin ID 73483
New! Plugin Severity Now Using CVSS v3

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


The DNS server running on the remote host is affected by a domain caching vulnerability.


According to its self-reported version number, the MaraDNS server running on the remote host is affected by an issue when updating DNS records in the server's cache that were revoked, possibly for malicious reasons. A remote attacker can continually query an affected host for the revoked domain, resulting in the domain name still resolving. This type of attack is known as a 'ghost domain' attack.


Upgrade to MaraDNS version / 1.4.12 / 2.0.06 or later or apply the relevant patch.
