Overview
CVE-2025-32868 is a security vulnerability that has been identified in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability exposes systems to SQL injection attacks, allowing authenticated remote attackers to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITY\NetworkService” permissions. This vulnerability is particularly dangerous due to its potential to compromise entire systems and cause data leakage.
Vulnerability Summary
CVE ID: CVE-2025-32868
Severity: High (8.8)
Attack Vector: Network
Privileges Required: Low
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 ‘ExportCertificate’ method used internally by the application. An attacker can exploit this vulnerability by sending a specially crafted SQL query to the server. The application fails to properly sanitize the SQL query, allowing the attacker to manipulate the SQL statement. The manipulated SQL statement could potentially execute arbitrary SQL code, bypassing authorization controls, and gaining access to the application’s database.
Conceptual Example Code
Consider this hypothetical scenario where an attacker sends a malicious SQL statement to the server. The server fails to sanitize the input, causing the SQL statement to be executed. Here’s what such a request might look like:
POST /ExportCertificate HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "certificate_id": "1; DROP TABLE users;" }In the sample above, the attacker is injecting a `DROP TABLE users;` command after the legitimate query. If the server processes this request, it could potentially lead to the deletion of the `users` table in the database.
Please note that this is a simplified example for illustrative purposes. In a real-world scenario, an attacker would likely use more complex and less detectable SQL injection techniques.
Mitigation
All users of TeleControl Server Basic are strongly encouraged to update to version V3.1.2.2 or later as soon as possible, as these versions contain a patch for this vulnerability. In the meantime, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can help detect and block SQL injection attacks.
Remember that while these measures can reduce the risk, they are not a substitute for patching the application and keeping it up to date. Regularly applying patches and updates is one of the most effective ways to protect your systems from known vulnerabilities.
