Overview
The cybersecurity industry has identified a new vulnerability within the TeleControl Server Basic application, dubbed CVE-2025-32864. This flaw affects all versions of the application prior to V3.1.2.2. The vulnerability poses a significant risk to organizations that have this software installed, as it could allow a remote attacker to manipulate the application’s database and execute code with “NT AUTHORITYNetworkService” permissions.
The severity of this vulnerability is high due to the potential system compromise and data leakage. It’s imperative to understand the details of this vulnerability, the systems and software it affects, and the recommended mitigation strategies to prevent potential exploitation and maintain the security of your systems.
Vulnerability Summary
CVE ID: CVE-2025-32864
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise and data leakage
Affected Products
No phone number, email, or personal info required.
Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The vulnerability lies in the GetSettings method, which is used internally by the TeleControl Server Basic application. An attacker can exploit this weakness by injecting SQL commands into the data input of this method.
This allows a remote attacker, with authenticated access, to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions. The only precondition for the attacker is to have access to the port 8000 on a system where a vulnerable version of the affected application is running.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit this vulnerability:
POST /GetSettings HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{ "settings_id": "1; DROP TABLE users; --" }In this example, the attacker sends a POST request to the GetSettings endpoint with a malicious payload that includes an SQL command (`DROP TABLE users; –`). This command would delete the users table from the database if executed.
Recommended Mitigation Strategy
The best way to prevent this vulnerability is to apply the vendor patch as soon as it becomes available. If this is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking SQL injection attempts.
It is also good practice to ensure that applications like TeleControl Server Basic are not accessible from the internet or untrusted networks, reducing the attack surface.
Finally, businesses should review their application and database permissions, ensuring that they follow the principle of least privilege. This means that each user and application should only have the minimum permissions necessary to perform their function. This can limit the potential impact of this and other similar vulnerabilities.
