CVE-2025-32844: SQL Injection Vulnerability in TeleControl Server Basic

Overview

In the ever-evolving landscape of cybersecurity, a new vulnerability has been identified, CVE-2025-32844, which poses a significant threat to users of TeleControl Server Basic. This vulnerability, originating from an SQL injection through an internally used ‘UnlockUser’ method, can lead to unauthorized access to the application’s database. It affects all versions of the application prior to V3.1.2.2. This vulnerability is of critical importance due to its potential for system compromise and data leakage, requiring immediate attention from system administrators and developers.

Vulnerability Summary

CVE ID: CVE-2025-32844
Severity: High (8.8 CVSS)
Attack Vector: Network
Privileges Required: Low (authenticated user)
User Interaction: Required
Impact: System compromise, data leakage, unauthorized access to application’s database

Affected Products

Product | Affected Versions

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

The exploit takes advantage of an SQL injection vulnerability present in the ‘UnlockUser’ method used internally by the application. An attacker, who has authenticated access to the system, can send specially crafted SQL queries to this method, which can manipulate the application’s database. This can lead to bypassing authorization controls, allowing the attacker to read from and write to the database, and potentially execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

Here is a conceptual example of how this vulnerability may be exploited using a malicious SQL query:

POST /UnlockUser HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "username": "admin', DROP TABLE users;--" }

This conceptual code sends a request to the ‘UnlockUser’ endpoint, injecting a malicious SQL statement that could potentially delete the entire ‘users’ table from the application’s database. Please note, this is a hypothetical example and the actual exploit may vary based on the specifics of the system and the attacker’s objectives.

Mitigation Guidance

It is strongly recommended to apply the vendor provided patch to mitigate this vulnerability. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these should not substitute for patching the system as soon as possible. Regularly updating software and maintaining a robust vulnerability management plan can help prevent similar threats in the future.
