CVE-2025-32850: Deep Dive into the SQL Injection Vulnerability in TeleControl Server Basic

Overview

The cybersecurity landscape is a constantly evolving battleground, with new vulnerabilities being discovered and exploited on an almost daily basis. One such vulnerability that has recently been identified is CVE-2025-32850. This vulnerability impacts all versions of the TeleControl Server Basic before V3.1.2.2. Its severity lies in the fact that it allows a remote attacker to bypass authorizations, read from and write to the app’s database, and even execute code with elevated permissions. Companies and individuals who rely on these systems for their day-to-day operations may find their systems compromised, leading to significant data leakage and potential business disruption.

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

The vulnerability lies in the ‘LockTcmSettings’ method, which is internally used by TeleControl Server Basic. This method is susceptible to SQL injection, a code injection technique often used to attack data-driven applications. This means that an attacker can insert malicious SQL statements into an entry field for execution, resulting in the ability to manipulate the application’s database.
The exploit is carried out by an authenticated remote attacker who has access to port 8000 on a victim’s system. The attacker can bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITY\NetworkService” permissions.

Conceptual Example Code

This is a
conceptual
example of how the vulnerability might be exploited. An attacker would send a specially crafted request to trick the server into executing malicious SQL commands.

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

In this example, the attacker sends a payload that contains a SQL statement designed to delete the ‘users’ table from the database. If the application is vulnerable and fails to properly sanitize the input, the SQL statement will be executed, leading to a data loss.
Please note that this is a hypothetical example and the actual exploit may vary depending on the specific implementation of the vulnerable application.
