New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 1.4
SynopsisThe remote name server is affected by a spoofing vulnerability.
DescriptionAccording to its self-reported version number, the version of the PowerDNS Recursor listening on the remote host is version 4.1.0. It is, therefore, affected by a flaw when handling DNSSEC signature validation of NSEC or NSEC3 records.
Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
Also, Nessus has not checked for the presence of the patch.
SolutionUpgrade to PowerDNS Recursor 4.1.1 or later. Alternatively, apply the patches referenced in the vendor advisories.
