CVE-2024-28066Public exploit

Root access via hard-coded weak password

Published Apr 8, 2024 · Updated Aug 15, 2024

Hard-coded credentials in Atos OpenScape Desk Phone IP firmware 1.10.4.3 allow remote attackers on the local network to gain root access. The firmware stores the same weak md5crypt hash for the Unix root account in /etc/shadow, and offline guessing recovers the embedded password. The public advisory does not identify which network service accepts this account, but successful use grants root control of the phone.
