AI-analyzed exploit summary This repository provides a Docker-based proof-of-concept for CVE-2019-6467, a vulnerability in BIND that allows nxdomain-redirect attacks. The exploit demonstrates how a non-existent domain query can be manipulated to redirect to an unintended domain.

A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally. The most likely scenario where this might occur is if the server, in addition to performing NXDOMAIN redirection for recursive clients, is also serving a local copy of the root zone or using mirroring to provide the root zone, although other configurations are also possible. Versions affected: BIND 9.12.0-> 9.12.4, 9.14.0. Also affects all releases in the 9.13 development branch.
