PowerDNS Authoritative < 4.0.5 Read Only Configuration Bypass (CVE-2017-15091)

high Nessus Plugin ID 106192

Language:

Synopsis

The remote name server is affected by a configuration bypass vulnerability.

Description

According to its self-reported version number, the version of the PowerDNS Authoritative listening on the remote host is prior to 4.0.5. It is, therefore, affected by a vulnerability in the API where a remote authenticated attacker can perform operations that affect the server state even if the api-readonly configuration is enabled.

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.

Solution

Upgrade to PowerDNS Authoritative 4.0.5 or later. Alternatively, apply the patches referenced in the vendor advisories.
