PowerDNS Recursor 4.0.x < 4.0.7 Multiple Vulnerabilities

medium Nessus Plugin ID 106193
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.

Synopsis

The remote name server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the version of the PowerDNS Recursor listening on the remote host is version 4.0.x prior to 4.0.7. It is, therefore, affected by multiple vulnerabilities:

- Insufficient validation of DNSSEC signatures.
(CVE-2017-15090)

- Cross-Site Scripting (XSS) in the web interface.
(CVE-2017-15092)

- Memory leak in DNSSEC parsing. (CVE-2017-15094)

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 Recursor 4.0.7 or later. Alternatively, apply the patches referenced in the vendor advisories.
