Overview
In the sphere of cybersecurity, the vulnerability identified as CVE-2025-32843 is causing a significant stir. This flaw, present in all versions of TeleControl Server Basic prior to V3.1.2.2, exposes the application to SQL injection attacks and consequently, potential system compromise or data leakage. This vulnerability is especially severe considering its potential to be exploited by authenticated remote attackers to bypass authorization controls and manipulate the application’s database.
The importance of addressing this vulnerability promptly stems from the potential damage it can inflict. An attacker can not only read and write to the application’s database but also execute code with “NT AUTHORITYNetworkService” permissions. Therefore, it is critical for organizations using TeleControl Server Basic to either update their software or implement mitigation measures as soon as possible.
Vulnerability Summary
CVE ID: CVE-2025-32843
Severity: High (CVSS 8.8)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Bypassing authorization controls, database manipulation, code execution with “NT AUTHORITYNetworkService” permissions
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 exploitation of this vulnerability revolves around the ‘LockUser’ method used internally by the application. An authenticated remote attacker can manipulate the SQL queries of this method to inject malicious SQL commands, leading to an SQL injection attack. Upon successful exploitation, the attacker gains access to read from and write to the application’s database. Furthermore, the attacker can execute code with “NT AUTHORITYNetworkService” permissions, bypassing authorization controls.
Conceptual Example Code
The following conceptual example demonstrates how the vulnerability might be exploited. This represents a malicious SQL command injected into the ‘LockUser’ method of the application:
'; DROP TABLE users; --This SQL statement, when concatenated into an existing query, would cause the ‘users’ table to be deleted from the database. This example code is merely conceptual and represents the kind of malicious SQL statements an attacker could use. Actual exploit code would be more complex and tailored to the specific database structure and data the attacker is attempting to manipulate or extract.
