Overview
A critical vulnerability, CVE-2025-32869, has been found in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability relates to SQL injection, one of the most severe web application security risks and allows for significant system compromise by an attacker. It exposes systems to potential unauthorized database manipulation and code execution, which can subsequently lead to data leakage or a complete system takeover.
The vulnerability affects organizations that rely on TeleControl Server Basic for remote control systems. Given the severity and the potential impact, it is crucial for organizations to understand and mitigate this vulnerability as soon as possible.
Vulnerability Summary
CVE ID: CVE-2025-32869
Severity: High, CVSS Score 8.8
Attack Vector: Network
Privileges Required: Low (Authenticated Access)
User Interaction: None
Impact: System compromise, Data leakage
Affected Products
No phone number, email, or personal info required.
Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The vulnerability resides in the ‘ImportCertificate’ method internally used by the TeleControl Server Basic application. An authenticated attacker can inject malicious SQL queries via this method. This SQL injection can bypass authorization controls, enabling the attacker to read and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions. Successful exploitation requires the attacker to have access to port 8000 on a system where a vulnerable version of the application is running.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This example is not meant to be a working exploit, but a demonstration of the attack concept.
POST /ImportCertificate HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
Authorization: Bearer [UserAuthToken]
{ "certificate": "'; DROP TABLE Users;--" }In this example, the attacker sends a POST request to the vulnerable endpoint `/ImportCertificate`. The malicious payload in the `certificate` parameter is an SQL command designed to delete the `Users` table from the database. If the application does not properly sanitize this input, the command will be executed, leading to potential data loss or unauthorized data access.
Mitigations
The ideal solution is to apply the vendor-provided patch that fixes this vulnerability. Users of TeleControl Server Basic should upgrade their software to version V3.1.2.2 or later as soon as possible.
In cases where immediate patching is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) that can detect and block SQL Injection attempts can serve as a temporary mitigation. However, these measures are not foolproof and should be used in conjunction with other security controls, like regular software updates and strong authentication mechanisms.
