CVE-2025-34034Known exploitationPublic exploitNetwork attack vector

Unauthenticated administrative access via hardcoded accounts

Published Jun 24, 2025 · Updated Apr 7, 2026

Hardcoded credentials in 5V Technologies Blue Angel Software Suite version 0 allow remote attackers to gain web-interface administration. The /cgi-bin/webctrl.cgi login handler accepts a shared, embedded set of default account credentials, including guest and privileged accounts. Network access to the device is sufficient; successful login exposes administrative functions, and the published exploit uses that access for command execution.
