Overview
This blog post provides comprehensive details about the CVE-2025-32823 vulnerability, a significant SQL Injection vulnerability found in all versions of TeleControl Server Basic preceding V3.1.2.2. This vulnerability poses a considerable risk to businesses and organizations that utilize this software as part of their infrastructure. A successful exploit could lead to a system compromise or data leakage, thereby threatening the integrity and confidentiality of the system and the data it holds.
Vulnerability Summary
CVE ID: CVE-2025-32823
Severity: High (CVSS: 8.8)
Attack Vector: Network
Privileges Required: Low (Authenticated Access)
User Interaction: None
Impact: Potential system compromise or data leakage

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 CVE-2025-32823 is a SQL injection flaw that resides in the ‘LockProject’ method used internally by the TeleControl Server Basic application. An authenticated remote attacker can exploit this vulnerability by sending specially crafted requests to the application on port 8000. These requests can manipulate the application’s database, bypassing authorization controls, reading from and writing to the database, and even executing code with “NT AUTHORITY\NetworkService” permissions.
Conceptual Example Code
The following is a conceptual example of a malicious SQL command that an attacker might use to exploit this vulnerability. This example serves only to illustrate the potential attack and should not be used for malicious purposes.
POST /LockProject HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{ "projectID": "1; DROP TABLE users; --" }In this example, the attacker sends a JSON payload with a projectID parameter. The value “1; DROP TABLE users; –” is an SQL command that, when executed, deletes the users table from the database.
Mitigation and Prevention
It’s critical to apply patches and updates from the vendor as soon as they become available. In this case, all users of TeleControl Server Basic should upgrade to version V3.1.2.2 or later to mitigate this vulnerability.
In addition to patching, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide a temporary mitigation measure. These systems can detect and block SQL injection attempts, reducing the risk of exploitation. However, these should not be seen as a permanent solution, as they may not block all possible attack vectors.
Always remember, staying proactive in patch management and maintaining a robust security posture is essential to protect your systems against such vulnerabilities.
