ISC BIND Multiple Vulnerabilities

medium Nessus Plugin ID 122507
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, the instance of ISC BIND 9 running on the remote name server is between 9.9.0 and 9.10.8-P1, 9.11.0 and 9.11.5-P2, 9.12.0 and 9.12.3-P2, 9.9.3-S1 and 9.11.5-S3, & 9.13.0 and 9.13.6. It is, therefore, affected by a zone transfer vulnerability.

- A zone transfer vulnerability exists for writable DLZ zones. An unauthenticated, remote attacker can exploit this, via allowzonexfr method bypass, to bypass transfer controls. (CVE-2019-6465)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to ISC BIND version 9.11.5-P4 / 9.11.5-P4 / 9.12.3-P4 / 9.13.7 or later.
