Comprehensive Technical Analysis of EUVD-2025-30193
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-30193 involves a hardcoded secret used for validating authentication tokens in the firmware of affected devices. This hardcoded secret can be extracted by an attacker, allowing them to bypass authentication mechanisms and gain complete access to the system.
Severity Evaluation:
- Base Score: 9.8 (Critical)
- Base Score Version: CVSS 3.1
- Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
The CVSS score of 9.8 indicates a critical vulnerability. The vector string highlights the following characteristics:
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): Low (L)
- Privileges Required (PR): None (N)
- User Interaction (UI): None (N)
- Scope (S): Unchanged (U)
- Confidentiality (C): High (H)
- Integrity (I): High (H)
- Availability (A): High (H)
This vulnerability is severe due to its high impact on confidentiality, integrity, and availability, combined with the ease of exploitation and the lack of required privileges or user interaction.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network-Based Attacks: Given the network attack vector, an attacker can exploit this vulnerability remotely.
- Firmware Extraction: An attacker could extract the firmware from the device, either through physical access or by intercepting firmware updates.
- Reverse Engineering: Once the firmware is obtained, the attacker can reverse-engineer it to locate the hardcoded secret.
Exploitation Methods:
- Token Forgery: With the hardcoded secret, the attacker can forge authentication tokens, bypassing the authentication process.
- Unauthorized Access: The attacker can gain complete access to the system, allowing them to perform unauthorized actions, including data exfiltration, system manipulation, and denial of service.
3. Affected Systems and Software Versions
The vulnerability affects the following products and versions from Dover Fueling Solutions:
- ProGauge MagLink LX 4: Versions prior to 4.20.3
- ProGauge MagLink LX Plus: Versions prior to 4.20.3
- ProGauge MagLink LX Ultimate: Versions prior to 5.20.3
4. Recommended Mitigation Strategies
Immediate Mitigation:
- Firmware Update: Upgrade to the latest firmware versions (4.20.3 for ProGauge MagLink LX 4 and ProGauge MagLink LX Plus, 5.20.3 for ProGauge MagLink LX Ultimate) that address this vulnerability.
