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

The exploit takes advantage of the ‘GetActiveProjects’ method which is vulnerable to SQL injection. An attacker who has access to port 8000 on a system running a vulnerable version of the TeleControl Server Basic can inject SQL commands. This allows the attacker to read from and write to the application’s database and execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This example shows how a malicious SQL command might be injected into the ‘GetActiveProjects’ method.

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

In this example, the attacker injects a SQL command (‘DROP TABLE users;’) that would delete the ‘users’ table from the database if executed.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch which corrects this vulnerability. In the absence of the vendor patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regular patching and updating of software to the latest versions is also a good practice to prevent exploitation of known vulnerabilities.

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

The exploit takes advantage of an SQL injection vulnerability in the ‘UnlockProject’ method of TeleControl Server Basic. An authenticated attacker can send specially crafted SQL queries to manipulate the application’s database. Given that the software executes these queries under NT AUTHORITYNetworkService permissions, a successful attack could result in unauthorized reading and writing of data, bypassing of authorization controls, and potential execution of arbitrary code.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited:

POST /UnlockProject HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{
"project_id": "1; DROP TABLE users;--"
}

In this example, an attacker sends a malicious payload that starts with a valid project_id (e.g., “1”), followed by an SQL statement to delete the users table, which is a common destructive action in SQL injection attacks. The “–” at the end is an SQL comment symbol, which makes the server ignore the rest of the original SQL query, preventing errors and making the injection attack successful.

Mitigation Guidance

Given the severity of this vulnerability, immediate action is recommended. If possible, apply the vendor-provided patch for TeleControl Server Basic version V3.1.2.2 or later. If this is not immediately feasible, consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation. These systems can detect and prevent SQL injection attacks, reducing your exposure to this vulnerability.

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

The vulnerability CVE-2025-32823 is a SQL injection flaw that resides in the ‘LockProject’ method used internally by the TeleControl Server Basic application. An authenticated remote attacker can exploit this vulnerability by sending specially crafted requests to the application on port 8000. These requests can manipulate the application’s database, bypassing authorization controls, reading from and writing to the database, and even executing code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

The following is a conceptual example of a malicious SQL command that an attacker might use to exploit this vulnerability. This example serves only to illustrate the potential attack and should not be used for malicious purposes.

POST /LockProject HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{ "projectID": "1; DROP TABLE users; --" }

In this example, the attacker sends a JSON payload with a projectID parameter. The value “1; DROP TABLE users; –” is an SQL command that, when executed, deletes the users table from the database.

Mitigation and Prevention

It’s critical to apply patches and updates from the vendor as soon as they become available. In this case, all users of TeleControl Server Basic should upgrade to version V3.1.2.2 or later to mitigate this vulnerability.

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

The exploit takes advantage of a SQL injection vulnerability in the ‘DeleteProject’ method used internally by the affected application. An attacker can craft a malicious SQL query that can bypass authorization controls when the method is invoked. The successful execution of this SQL query provides the attacker with read and write access to the application’s database. The vulnerability could also allow the attacker to execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

Consider a scenario where an attacker might craft a malicious SQL query to exploit this vulnerability:

POST /DeleteProject HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer <authentication token>
{ "project_id": "1; DROP TABLE users;" }

In this
hypothetical
example, the attacker attempts to delete a project but also includes a SQL injection (‘1; DROP TABLE users;’) in the query. When the ‘DeleteProject’ method is invoked, it could potentially interpret the semicolon as the end of one command and the start of another, leading to the execution of the malicious SQL query.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the latest patch provided by the vendor that addresses this specific issue. If for any reason, the patch cannot be immediately applied, it is recommended to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. The mentioned systems can help detect and prevent exploitation of this vulnerability by monitoring network traffic for suspicious activities.
