NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

A flaw was found in BusyBox's httpd web server. When configured with system password authentication, a user existence oracle may exist in certain build configurations. An attacker could distinguish existing from non-existing usernames by observing authentication failure behavior. Impact is limited to username enumeration and requires non-default compile options or uncommon password file states; default BusyBox builds with shadow password support are not affected.
