Overview
The cybersecurity landscape is facing a new threat in the form of a vulnerability discovered in all versions of TeleControl Server Basic prior to version V3.1.2.2. This vulnerability, designated CVE-2025-32852, is a severe SQL injection vulnerability that could lead to the potential compromise of the entire system or data leakage. The issue lies with the application’s internally used ‘LockDatabaseSettings’ method, which is susceptible to an SQL injection attack. The ramifications of a successful exploit could be extensive, as it affects anyone running a vulnerable version of the TeleControl Server Basic.
Vulnerability Summary
CVE ID: CVE-2025-32852
Severity: High (8.8 CVSS)
Attack Vector: Network-based
Privileges Required: User-level
User Interaction: Required
Impact: Potential system compromise or 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
An attacker who is able to authenticate and gain access to port 8000 on a system running a vulnerable version of the TeleControl Server Basic software can exploit this vulnerability. By injecting malicious SQL code through the ‘LockDatabaseSettings’ method, the attacker can bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions.
Conceptual Example Code
The following is a conceptual example of how an attacker might exploit this vulnerability. This is a pseudocode representation of how a malicious SQL query might be sent via an HTTP POST request:
POST /LockDatabaseSettings HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"settingsLock": "'; DROP TABLE users; --"
}In this example, the `settingsLock` parameter is being used to inject a SQL command (`DROP TABLE users;`) that could lead to destructive actions on the database.
Recommendations for Mitigation
The best course of action to mitigate this vulnerability is to apply the latest patch from the vendor. The patch addresses the SQL injection vulnerability in the ‘LockDatabaseSettings’ method and should be applied as soon as possible. For temporary mitigation or added security, a WAF (Web Application Firewall) or IDS (Intrusion Detection System) could be used to detect and block attempts at SQL injection. However, these are only temporary solutions and do not replace the need for patching the software.
