Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Pi-hole Web v4.3.2 (aka AdminLTE) allows Remote Code Execution by privileged dashboard users via a crafted DHCP static lease.
