CVE-2025-54807

Comprehensive Technical Analysis of CVE-2025-54807

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-54807 CVSS Score: 9.8

The vulnerability described in CVE-2025-54807 involves a hardcoded secret used for validating authentication tokens in the device firmware. This hardcoding of a critical security element is a significant flaw, as it allows an attacker who obtains the signing key to bypass authentication mechanisms, thereby gaining complete access to the system.

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: Complete system access, potential for full control over the device.
• Exploitability: High, as the hardcoded secret can be extracted from the firmware.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Firmware Extraction: An attacker could extract the firmware from the device and analyze it to discover the hardcoded secret.
2. Reverse Engineering: Using reverse engineering techniques, an attacker could identify the hardcoded secret within the firmware.
3. Supply Chain Attacks: Compromising the supply chain to obtain the firmware or the device itself.

Exploitation Methods:

1. Authentication Bypass: Once the hardcoded secret is obtained, an attacker can generate valid authentication tokens, bypassing the authentication process.
2. Privilege Escalation: With valid tokens, the attacker can escalate privileges and gain full control over the system.
3. Data Exfiltration: The attacker can exfiltrate sensitive data, manipulate system settings, or perform other malicious activities.

3. Affected Systems and Software Versions

Affected Systems:

• Devices using the firmware with the hardcoded secret for authentication token validation.
• Specifically mentioned in the references: ProGauge MagLink LX-4 Console by Dover Fueling Solutions.

Software Versions:
