CVE-2025-32861: Critical SQL Injection Vulnerability in TeleControl Server Basic

Overview

In our technologically advancing world, the significance of cybersecurity is ever-growing. One of the recent vulnerabilities that have come to light is CVE-2025-32861, a critical SQL injection vulnerability in TeleControl Server Basic. This vulnerability has the potential to allow a remote attacker to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITY\NetworkService” permissions, leading to potential system compromise or data leakage. It is essential to address such vulnerabilities promptly to safeguard our systems and data.

Vulnerability Summary

CVE ID: CVE-2025-32861
Severity: Critical (CVSS: 8.8)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works

This vulnerability stems from the application’s ‘UpdateTraceLevelSettings’ method, which is not properly sanitized for SQL commands. As a result, an authenticated attacker can execute arbitrary SQL commands which can lead to unauthorized access and manipulation of the application’s database. Additionally, the attacker can execute code with “NT AUTHORITY\NetworkService” permissions, leading to potential system compromise.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This pseudo SQL injection attack targets the ‘UpdateTraceLevelSettings’ method:

POST /UpdateTraceLevelSettings HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"traceLevel": "1; DROP TABLE users;"
}

In this example, the SQL command ‘DROP TABLE users;’ is injected into the ‘traceLevel’ parameter, which could result in the deletion of the ‘users’ table from the database if executed.

Mitigation Guidance

The most effective mitigation strategy for this vulnerability is to apply the vendor patch that updates TeleControl Server Basic to version V3.1.2.2 or later. If immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these are not long-term solutions and can only serve to buy time until the patch can be applied. Regularly updating and patching your software is the best defense against such vulnerabilities.
