high Nessus Plugin ID 242965

Language:

Synopsis

An ad-blocking DNS server web-based admin interface is affected by a remote code execution vulnerability.

Description

The version of Pi-Hole Web running on the remote web server is 4.3.2 prior to 4.3.3. It is, therefore, affected by a remote code execution vulnerability by privileged dashboard users via a crafted DHCP static lease.

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

Solution

Upgrade Pi-Hole Web to version 4.3.3 or later.
