Overview
The cybersecurity landscape is ever-evolving, and our focus today is on a critical vulnerability identified in TeleControl Server Basic, a widely used application in the IT industry. Identified as CVE-2025-32824, this vulnerability poses a significant threat to organizations that have not updated their systems to the latest version (V3.1.2.2).
The exploit gives attackers the ability to bypass authorization controls, read and write to the application’s database, and execute code with NT AUTHORITY\NetworkService permissions. The issue lies within the internally used ‘UnlockProject’ method, which is susceptible to SQL injection attacks. Given the potential for system compromise and data leakage, it’s crucial that organizations understand and act upon this threat accordingly.
Vulnerability Summary

Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The exploit takes advantage of an SQL injection vulnerability in the ‘UnlockProject’ method of TeleControl Server Basic. An authenticated attacker can send specially crafted SQL queries to manipulate the application’s database. Given that the software executes these queries under NT AUTHORITY\NetworkService permissions, a successful attack could result in unauthorized reading and writing of data, bypassing of authorization controls, and potential execution of arbitrary code.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited:
POST /UnlockProject HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{
"project_id": "1; DROP TABLE users;--"
}In this example, an attacker sends a malicious payload that starts with a valid project_id (e.g., “1”), followed by an SQL statement to delete the users table, which is a common destructive action in SQL injection attacks. The “–” at the end is an SQL comment symbol, which makes the server ignore the rest of the original SQL query, preventing errors and making the injection attack successful.
Mitigation Guidance
Given the severity of this vulnerability, immediate action is recommended. If possible, apply the vendor-provided patch for TeleControl Server Basic version V3.1.2.2 or later. If this is not immediately feasible, consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation. These systems can detect and prevent SQL injection attacks, reducing your exposure to this vulnerability.
