Overview

We are discussing a high severity SQL injection vulnerability identified as CVE-2025-30003, which affects all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability is significant as it allows an authenticated remote attacker to bypass authorization controls, thus enabling them to read and write to the application’s database. This constitutes a significant security risk, as it can potentially enable system compromise or data leakage.
The vulnerability is of particular concern to organizations that use TeleControl Server Basic for their operations as it exposes their systems to potential cyber attacks. The vulnerability is exploitable through the internally used ‘UpdateProjectConnections’ method and requires the attacker to have access to port 8000 on a system where a vulnerable version of the application is executed on.

Vulnerability Summary

CVE ID: CVE-2025-30003
Severity: High – 8.8 (CVSS score)
Attack Vector: Network
Privileges Required: Low (Authenticated user)
User Interaction: Required
Impact: System Compromise, Data Leakage

Affected Products

TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works

The vulnerability occurs due to a lack of proper sanitization of user inputs within the ‘UpdateProjectConnections’ method. This allows an attacker to send specially crafted SQL commands, leading to SQL injection. An attacker who successfully exploits this vulnerability can manipulate SQL queries, allowing them to read from or write to the application’s database and execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

An example of how this vulnerability might be exploited is shown below:

POST /UpdateProjectConnections HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"projectID": "1; DROP TABLE users;"
}

In this example, the attacker injects a malicious SQL command (`DROP TABLE users;`) to delete the users table from the database. This is a simple example. An actual attack could involve more sophisticated commands to exfiltrate data, manipulate data, or gain unauthorized access.

Recommendations for Mitigation

Users are strongly recommended to update their TeleControl Server Basic to the latest version (V3.1.2.2 or later) as soon as possible, as this contains the vendor patch which addresses this vulnerability.
As a temporary mitigation measure, users can implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block potential SQL injection attacks. However, this does not replace the need for patching the software as it only offers a layer of protection against this specific attack vector.

Overview

In this article, we will be discussing a critical vulnerability that has been identified in all versions of TeleControl Server Basic with versions less than V3.1.2.2. This vulnerability can potentially lead to system compromise or data leakage, posing a significant risk to any organizations relying on these versions of the software for their operations. This matter is of high importance as the successful exploitation of this vulnerability could allow an authenticated remote attacker to bypass authorization controls, read from and write to the application’s database, and execute code with specific permissions.

Vulnerability Summary

Privileges Required: Low (Authenticated User)
User Interaction: None
Impact: System compromise, data leakage

TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works

This exploit leverages an SQL Injection vulnerability in the ‘UpdateConnectionVariables’ method used internally by the affected application. An attacker, who has authenticated access to the system, can send crafted SQL queries through this method to manipulate the application’s database. This can lead to unauthorized read or write operations and even execution of malicious code with “NT AUTHORITYNetworkService” permissions. The successful execution of the attack requires the attacker to access port 8000 on the targeted system.

Conceptual Example Code

Below is a conceptual example of exploiting this vulnerability. This example uses a malicious SQL query embedded within a regular request to the ‘UpdateConnectionVariables’ method:

POST /UpdateConnectionVariables HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "variable": "'; DROP TABLE users; --" }

In this example, the SQL query `’; DROP TABLE users; –` is injected into the request, which if processed by the server, can lead to destructive consequences such as deleting the users table from the database.

Mitigation Guidance

To mitigate this vulnerability, users of TeleControl Server Basic are strongly recommended to apply the vendor patch as soon as possible. The patch updates the application to a version where the vulnerability has been resolved. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy by monitoring and blocking suspicious activities.

Overview

There is a new security issue in the cybersecurity landscape that is raising concerns among professionals and organizations alike. The issue is a significant vulnerability identified in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability is of particular interest due to its potential to allow a remote and authenticated attacker to bypass the authorization controls and manipulate the application’s database. The ability to execute code with “NT AUTHORITYNetworkService” permissions further exacerbates the risk. This vulnerability can potentially cause system compromises or data leakage, making it crucial for cybersecurity professionals to understand and mitigate its impact.

Vulnerability Summary

CVE ID: CVE-2025-29905
Severity: High – 8.8
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise, unauthorized read/write access to the application’s database, potential data leakage.

TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works

The vulnerability occurs because of an issue with the ‘RestoreFromBackup’ method used internally by the TeleControl Server Basic application. This method is susceptible to SQL injection attacks, allowing a malicious attacker to bypass the application’s authorization controls. The attacker can then read from and write to the application’s database and execute code with “NT AUTHORITYNetworkService” permissions. For a successful attack, the attacker must have access to port 8000 on a system where a vulnerable version of the affected application is being executed.

Conceptual Example Code

A potential SQL injection attack exploiting this vulnerability might look conceptually like this:

POST /RestoreFromBackup HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"database_name": "main_db",
"backup_file": "' OR '1'='1'; -- "
}

In this example, the attacker is injecting a common SQL injection payload into the `backup_file` parameter. If the application doesn’t properly sanitize inputs, this could allow the attacker to bypass authorization controls and interact directly with the application’s database.
To mitigate this vulnerability, users are advised to apply the vendor patch or use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as a temporary measure. Stay vigilant and ensure that your systems are always updated with the latest security patches to protect against such vulnerabilities.
