CVE-2025-34034 is a vulnerability classified under CWE-798 (Use of Hard-coded Credentials) affecting the Blue Angel Software Suite by 5VTechnologies deployed on embedded Linux systems. The application includes multiple undocumented default and hardcoded user accounts that enable attackers without authentication or with low privileges to escalate to administrative access on the device's web interface. The vulnerability was publicly disclosed in June 2025 with a CVSS 4.0 base score of 9.3, reflecting network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability. Exploitation evidence was observed by Shadowserver Foundation in January 2025. There is no vendor advisory or patch information provided, and the product is not cloud-hosted, so remediation depends on vendor action or user mitigation.

The vulnerability allows unauthenticated or low-privilege attackers to gain administrative access to the web interface of devices running the Blue Angel Software Suite. This can lead to full control over the affected device, compromising confidentiality, integrity, and availability. The CVSS score of 9.3 indicates critical severity with high impact on all security properties. Exploitation evidence has been observed, confirming active risk. No known widespread exploitation beyond this has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix information is available, users should restrict network access to affected devices, disable or change default credentials if possible, and monitor for updates from 5VTechnologies. Avoid exposing the device's web interface to untrusted networks until a vendor-provided fix is released.
