CVE-2025-32826: SQL Injection Vulnerability in TeleControl Server Basic

Overview

A serious security vulnerability, identified as CVE-2025-32826, has been discovered in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability presents a significant risk to any organization utilizing this software, as it can allow an authenticated remote attacker to manipulate the application’s database, bypass authorization controls, and even execute code with elevated permissions. This could potentially lead to system compromise or data leakage, making it a matter of utmost importance that this vulnerability is addressed urgently.

Affected Products

Product | Affected Versions

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

The exploit takes advantage of the ‘GetActiveProjects’ method which is vulnerable to SQL injection. An attacker who has access to port 8000 on a system running a vulnerable version of the TeleControl Server Basic can inject SQL commands. This allows the attacker to read from and write to the application’s database and execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This example shows how a malicious SQL command might be injected into the ‘GetActiveProjects’ method.

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

In this example, the attacker injects a SQL command (‘DROP TABLE users;’) that would delete the ‘users’ table from the database if executed.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch which corrects this vulnerability. In the absence of the vendor patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regular patching and updating of software to the latest versions is also a good practice to prevent exploitation of known vulnerabilities.
