CVE-2025-31352: Critical SQL Injection Vulnerability in TeleControl Server Basic

Overview

In the realm of cybersecurity, a new vulnerability has been identified that poses a severe threat to the security and integrity of systems running TeleControl Server Basic versions below V3.1.2.2. This vulnerability, identified as CVE-2025-31352, hinges on the potential for SQL injection, allowing a malicious actor to bypass authorization controls and interact directly with the application’s database. Given the widespread use of TeleControl Server Basic in various industries, a successful exploit could potentially lead to significant data leaks or system compromises.

Vulnerability Summary

CVE ID: CVE-2025-31352
Severity: Critical (8.8/10 CVSS score)
Attack Vector: Network
Privileges Required: Low (Authenticated User)
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

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

The vulnerability lies in the ‘UpdateGateways’ method used internally by the TeleControl Server Basic software. This method is vulnerable to SQL injection, a code injection technique where attackers can insert malicious SQL statements into an entry field for execution. An authenticated attacker can exploit this vulnerability to manipulate the application’s database, bypassing authorization controls and potentially reading from and writing to the database. This could lead to system compromise or data leakage. The attacker needs to have access to port 8000 on the system running a vulnerable version of the application.

Conceptual Example Code

Here’s a conceptual example of how this vulnerability might be exploited, using a hypothetical malicious SQL statement:

POST /UpdateGateways HTTP/1.1
Host: vulnerable_server.com:8000
Content-Type: application/json
{
"gateway_id": "1; DROP TABLE users"
}

In this example, the attacker injects the SQL command `DROP TABLE users` into the `gateway_id` parameter, potentially deleting an entire user table from the database if the application’s server processes it.
