CVE-2025-54807: CWE-321 in Dover Fueling Solutions ProGauge MagLink LX 4
The secret used for validating authentication tokens is hardcoded in device firmware for affected versions. An attacker who obtains the signing key can bypass authentication, gaining complete access to the system.
AI Analysis
Technical Summary
The ProGauge MagLink LX 4 device from Dover Fueling Solutions contains a hardcoded secret key in its firmware used for validating authentication tokens (CWE-321). An attacker who extracts this key can bypass authentication controls, resulting in full system compromise. The vulnerability is remotely exploitable without privileges or user interaction, reflected by a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). No official patch or fix has been published, and the device is not cloud-hosted, so remediation requires vendor firmware updates.
Potential Impact
Successful exploitation allows an unauthenticated attacker to bypass authentication mechanisms entirely, gaining full control over the affected device. This compromises confidentiality, integrity, and availability of the system, potentially leading to unauthorized operations or disruption of fuel dispensing infrastructure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a firmware update is available, restrict physical and network access to the device to trusted personnel only. Monitor for any vendor announcements regarding patches or mitigations.
