CVE-2025-32832: SQL Injection Vulnerability in TeleControl Server Basic

Overview

A serious vulnerability, identified as CVE-2025-32832, has been discovered in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability enables an authenticated attacker to perform a SQL injection, which could result in unauthorized access to the application’s database. Given that the application is frequently used in critical infrastructure environments, this vulnerability represents a significant risk and has the potential to compromise systems or cause data leakage if not adequately addressed.

Vulnerability Summary

CVE ID: CVE-2025-32832
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low (Authenticated Access)
User Interaction: None
Impact: Potential system compromise or data leakage

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

The exploit leverages the ‘LockProjectUserRights’ method used internally by the TeleControl Server Basic application. By injecting malicious SQL commands, an attacker can manipulate the application’s database, bypassing authorization controls. This would enable the attacker to read from and write to the database, potentially accessing sensitive data or modifying application configurations. The attacker could also execute code with “NT AUTHORITYNetworkService” permissions, further compromising the system.

Conceptual Example Code

This is a conceptual example of how an attacker might exploit this vulnerability using a specially crafted HTTP request:

POST /LockProjectUserRights HTTP/1.1
Host: vulnerable.example.com:8000
Content-Type: application/json
{
"user": "admin",
"project": "target",
"rights": "1; DROP TABLE users; --"
}

In this example, the attacker sends a POST request to the ‘LockProjectUserRights’ endpoint, injecting a SQL command to drop the ‘users’ table from the database. Note that this is a hypothetical example and the actual exploit would likely be more complex and targeted.

Mitigation

All users of TeleControl Server Basic are strongly advised to upgrade to version V3.1.2.2 or later as soon as possible. If upgrading is not immediately feasible, users can use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. However, these are not foolproof solutions and the system could still be vulnerable. Therefore, applying the vendor patch remains the most secure solution.
