CVE-2025-32865: SQL Injection Vulnerability in TeleControl Server Basic

Overview

A critical vulnerability has been discovered in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability, designated as CVE-2025-32865, exposes the software to SQL injection attacks, potentially allowing an authenticated remote attacker to bypass authorization controls and manipulate the application’s database. The severity and widespread use of the affected software make it a significant threat to businesses and organizations that have implemented the software in their networks. Understanding this vulnerability, its potential impacts, and the mitigation strategies is essential for maintaining a robust cybersecurity posture.

Vulnerability Summary

CVE ID: CVE-2025-32865
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low (Authenticated User)
User Interaction: None
Impact: Bypass of authorization controls, 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 ‘CreateLog’ method used internally by the application. An attacker who has network access and user-level authentication can craft a malicious SQL query that is injected into the application via this method. This allows the attacker to read from and write to the application’s database, bypassing the intended authorization controls. In a successful attack, the attacker could potentially execute code with “NT AUTHORITY\NetworkService” permissions and compromise the system.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could look like this:

POST /CreateLog HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer authenticated_user_token
{ "log_entry": "valid_log_entry'; DROP TABLE users; --" }

In this example, the “log_entry” field is supposed to contain a regular log entry. However, an attacker inserts a valid log entry followed by a semicolon and then a SQL command to drop the ‘users’ table. The ‘–‘ at the end is a comment marker in SQL, which makes the application ignore anything that follows, ensuring that the malicious SQL command is executed.

Recommended Mitigation

Users of the affected versions of TeleControl Server Basic are strongly urged to apply the vendor patch to update the software to version V3.1.2.2 or later. In situations where immediate patching is not possible or feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide a temporary mitigation by detecting and blocking SQL injection attacks.
