CVE-2023-34123Network attack vector

Administrative access via predictable password-reset keys

Published Jul 12, 2023 · Updated Nov 6, 2024

Hard-coded key use in SonicWall GMS 9.3.2-SP1 and earlier and Analytics 2.5.0.4-R7 and earlier allows remote attackers to reset admin passwords. The /appliance password-reset code derives reset tokens with a hard-coded 3DES key shared across installations and with other inputs available without authentication. A target must be registered or use Closed Network mode; a forged token grants administrative appliance access and access to managed devices.
