Overview
The cybersecurity world is no stranger to vulnerabilities, and the uncovered CVE-2025-55068 is a pressing example. This flaw is inherent in the Dover Fueling Solutions ProGauge MagLink LX4 Devices, a widely used product in the fueling industry. The vulnerability arises from the device’s failure to handle Unix time values beyond a specific point. This failure can be exploited by an attacker to manually change the system time, potentially causing authentication errors and leading to a denial-of-service condition.
Given the wide use of these devices and the potential impact, this vulnerability is of significant concern. It poses a severe threat to users, potentially leading to system compromise or data leakage.

How the Exploit Works
The vulnerability exists due to a flaw in the Dover Fueling Solutions ProGauge MagLink LX4 devices’ time management. These devices fail to handle Unix time values beyond a certain threshold. An attacker can take advantage of this limitation by manually manipulating the system time. This manipulation may cause the system to encounter errors during authentication processes, consequently leading to a denial-of-service condition.
Conceptual Example Code
In this conceptual scenario, the attacker executes a shell command to change the system time, thereby exploiting the vulnerability. It can be demonstrated as follows:
# The attacker sets the system time to a value beyond the Unix time threshold
date -s "@2147483647"This command sets the system time to the maximum Unix timestamp (31st December 2038, 19:14:07 GMT). As the ProGauge MagLink LX4 device cannot handle this timestamp, it will cause an error in the authentication mechanism, leading to a denial-of-service condition and potentially compromising the system or leaking data.
Mitigation
Users of the affected devices are strongly recommended to apply the vendor-supplied patch as soon as possible. This patch will correct the issue and prevent exploitation of this vulnerability. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, this is not a complete solution and the patch should still be applied as the definitive remedy.
