Overview
A critical security vulnerability, CVE-2025-32848, has been discovered in all versions of TeleControl Server Basic prior to V3.1.2.2. The vulnerability is a severe SQL injection flaw that could allow an attacker to bypass authorization controls, manipulate the application’s database, and potentially execute arbitrary code. This vulnerability is particularly concerning as it affects a wide range of systems and, if successfully exploited, could lead to system compromise or data leakage.
The vulnerability is critical due to its potential to give an attacker access to sensitive data and system resources. As such, it is highly recommended that all organizations and individuals using the affected versions of TeleControl Server Basic take immediate action to mitigate this risk.
Vulnerability Summary
CVE ID: CVE-2025-32848
Severity: High (8.8 CVSS)

Privileges Required: Low
User Interaction: None
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
The vulnerability exists due to inadequate input sanitization in the ‘LockSmtpSettings’ method, which is used internally by the application. An attacker who sends carefully crafted SQL code as part of their input to this function can trigger an SQL injection attack. This would allow them to manipulate the database, including reading from and writing to it, and potentially executing code with “NT AUTHORITYNetworkService” permissions.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP request, shell command, or pseudocode.
POST /LockSmtpSettings HTTP/1.1
Host: target.example.com:8000
Content-Type: application/x-www-form-urlencoded
smtpSettings='; DROP TABLE users; --In this example, the attacker sends a malicious SQL command (`DROP TABLE users`) which would effectively delete the entire ‘users’ table from the database, if executed. The `–` at the end of the command is an SQL comment, causing the database server to ignore the rest of the original query, preventing syntax errors.
Mitigation
Users of affected versions of TeleControl Server Basic are advised to update to version V3.1.2.2 or later as soon as possible to address this vulnerability. If an immediate update is not possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure is recommended. These systems should be configured to detect and block SQL Injection attacks.
