CVE-2025-34034: 
Linux Ubuntu vulnerability analysis and mitigation

A hardcoded credential vulnerability (CVE-2025-34034) was discovered in the Blue Angel Software Suite deployed on embedded Linux systems. The vulnerability was disclosed on June 23, 2025, and affects all versions of the software. The application contains multiple known default and hardcoded user accounts that are not documented in public documentation, allowing unauthenticated or low-privilege attackers to gain administrative access to the device's web interface (VulnCheck Advisory, NVD).

The vulnerability is classified as CWE-798 (Use of Hard-coded Credentials) and has received a CVSS v4.0 base score of 9.3 CRITICAL with the vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. The vulnerability stems from multiple hardcoded user accounts embedded in the system, including default credentials that are not publicly documented (VulnCheck Advisory).

The impact of this vulnerability is severe as it allows attackers to gain administrative access to the device's web interface without requiring authentication or with minimal privileges. This access could potentially lead to complete system compromise, unauthorized configuration changes, and access to sensitive information (NVD).
