Overview
The cybersecurity community has discovered a severe vulnerability affecting Dover Fueling Solutions ProGauge MagLink LX Consoles. Identified as CVE-2025-5310, this security flaw exposes an undocumented and unauthenticated Target Communication Framework (TCF) interface on a specific port, allowing unauthorized users to create, delete, or modify files. As a result, potential remote code execution could occur, leading to system compromise or data leakage. The vulnerability matters, as it affects devices used worldwide, potentially putting millions of systems at risk.

How the Exploit Works
The exploit works by taking advantage of an unsecured and undocumented TCF interface on a specific port. Through this interface, an attacker can remotely access the system, enabling them to create, delete, or modify files. This could potentially lead to remote code execution, which could compromise the system, alter its functionality, or lead to data leakage. The attack does not require any user interaction or privileges, making it particularly dangerous.
Conceptual Example Code
The following pseudocode demonstrates a conceptual example of how an attacker might exploit this vulnerability:
POST /tcf_interface HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"action": "create",
"path": "/path/to/vulnerable/file",
"content": "malicious_code_here"
}In the above example, an attacker sends an HTTP POST request to the TCF interface, instructing it to create a file with malicious code.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, organizations can use Web Application Firewalls (WAF) and Intrusion Detection Systems (IDS) as temporary mitigation measures to detect and block any suspicious activity. It is also recommended to monitor all network traffic and restrict access to the TCF interface to known IP addresses only.
Finally, it is essential to keep all devices updated with the latest patches and updates and maintain a robust cybersecurity strategy to protect against such vulnerabilities.
