CVE-2025-32858: SQL Injection Vulnerability in TeleControl Server Basic

Overview

In the realm of cybersecurity, vulnerabilities are often an inevitable part of software development. Recently, a significant vulnerability, CVE-2025-32858, has been identified in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability is of particular concern as it allows for SQL injection, a common hacking technique used to manipulate databases, through an internally used method. This exploit has the potential to affect any organization or individual using the affected versions of this application, leading to potential system compromise or data leakage.
The severity of this issue is underlined by the fact that a successful attack could provide an attacker with access to sensitive data or even control over the system. Therefore, it is crucial for users of TeleControl Server Basic to understand the details of this vulnerability and take the necessary steps to mitigate the risks it poses.

Product | Affected Versions

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

The vulnerability lies in the ‘UpdateWebServerGatewaySettings’ method internally used by TeleControl Server Basic. An attacker can manipulate this function with malicious SQL statements. This SQL injection can bypass authorization controls and gain access to the application’s database. The attacker can read from and write to the database, even execute code with “NT AUTHORITY\NetworkService” permissions. The exploit requires the attacker to be able to access port 8000 on a system running a vulnerable version of the application.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability. This example uses a malicious SQL statement in a HTTP POST request to the vulnerable endpoint.

POST /UpdateWebServerGatewaySettings HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "serverGatewaySettings": "'; DROP TABLE users; --" }

In this example, the malicious SQL statement `’; DROP TABLE users; –` is injected into the application through the serverGatewaySettings parameter. This could cause the application to delete the users table from its database, leading to potential data loss and disruption of service.
Remember, this is a conceptual example and the actual exploit could take various forms depending on the attacker’s goals and the specific configuration of the system being targeted.
