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.
In addition to patching, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide a temporary mitigation measure. These systems can detect and block SQL injection attempts, reducing the risk of exploitation. However, these should not be seen as a permanent solution, as they may not block all possible attack vectors.
Always remember, staying proactive in patch management and maintaining a robust security posture is essential to protect your systems against such vulnerabilities.

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.

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

The vulnerability lies within the ‘UpdateProject’ method of the TeleControl Server Basic application. An attacker, given authenticated access and network connectivity to the target system, can inject malicious SQL commands through this method. This allows the attacker to bypass authorization controls and interact with the application’s database. This interaction may include reading, writing, or manipulating data, and even executing code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

This is a conceptual example of how an attacker might exploit the vulnerability using a SQL injection attack:

POST /UpdateProject HTTP/1.1
Host: target.example.com:8000
Content-Type: application/sql
{ "project_update": "' OR '1'='1'; DROP TABLE users; --" }

In the above example, the attacker is injecting a SQL command (‘ OR ‘1’=’1′; DROP TABLE users; –) into the project_update field. This command is designed to bypass authorization controls (the ‘ OR ‘1’=’1′ part always evaluates to true) and then deletes the users table from the database.
Remember, this is a conceptual example. The actual payload will vary depending on the database structure and the attacker’s objectives.

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

The vulnerability in question, CVE-2025-31353, exploits a flaw in the ‘UpdateOpcSettings’ method used internally by TeleControl Server Basic. This method is susceptible to SQL injection attacks, which allows an authenticated remote attacker to read from and write to the application’s database. This could result in bypassing of authorization controls and execution of code with “NT AUTHORITYNetworkService” permissions. For a successful attack, the attacker needs to access port 8000 on a system where a vulnerable version of the affected application is being executed.

Conceptual Example Code

Here’s a conceptual example illustrating how an attacker might exploit this vulnerability. Note that this is purely hypothetical and is intended for understanding purposes only.

POST /UpdateOpcSettings HTTP/1.1
Host: target.example.com
Content-Type: application/sql
{
"settings_update":
"'; DROP TABLE users; --"
}

In this example, the attacker is crafting an HTTP POST request to send a malicious SQL statement to the server. The SQL statement is designed to drop the ‘users’ table from the database, demonstrating how an attacker could manipulate the database through SQL injection.

Mitigation

The most effective way to mitigate this vulnerability is to apply the vendor patch. Users are strongly advised to upgrade to TeleControl Server Basic version V3.1.2.2 or later. If immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. The WAF or IDS should be configured to detect and block SQL injection attacks. However, this is a temporary solution and may not provide complete protection against the vulnerability. Therefore, applying the vendor patch at the earliest opportunity is highly recommended.
