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

The exploit works by an attacker sending specifically crafted SQL commands to the ‘UnlockGateway’ method of the TeleControl Server Basic. Since the application does not adequately sanitize the user-supplied input, this can result in SQL injection. This would allow an attacker with network access to the application to access sensitive information, manipulate the application database, and execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This would involve sending a malicious SQL command to the ‘UnlockGateway’ method through a POST request.

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

In this example, the SQL command `DROP TABLE users;` would be executed on the server, potentially deleting a table from the database. Note that this is a simplified example, and actual SQL injection attacks can be much more complex and damaging.

Mitigation and Remediation

Users are advised to immediately apply the patch provided by the vendor that addresses this vulnerability. In cases where immediate patching is not feasible, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to block or detect SQL injection attacks. However, these measures only provide temporary relief and cannot fully resolve the vulnerability. Therefore, upgrading to a patched version of the software should be done as soon as possible.

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

The exploit targets the ‘ImportConnectionVariables’ method used internally by the application. A malicious user can craft a special SQL query that, when executed, will manipulate the application’s database, allowing for data read and write operations. This provides an attack path for the execution of arbitrary code with “NT AUTHORITYNetworkService” permissions. This attack requires the attacker to have access to port 8000 on the system where the vulnerable version of TeleControl Server Basic is being executed.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This is a hypothetical SQL injection payload that might be used:

POST /ImportConnectionVariables HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
db_var="1'; DROP TABLE users; --"

In this example, the attacker tries to delete the “users” table from the database. Please note that this is a conceptual example and the actual exploit may vary based on the attacker’s motive and the application’s database structure.

Recommended Mitigation

It is strongly recommended to apply the vendor patch to mitigate this vulnerability. For those who cannot immediately apply the patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation. Please ensure your WAF/IDS is configured properly to detect and prevent SQL Injection attacks.

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

An authenticated attacker can exploit this vulnerability by sending specially crafted SQL statements to the ‘UpdateConnectionVariableArchivingBuffering’ method of the TeleControl Server Basic. The affected application fails to properly sanitize user-supplied input before passing it to the SQL query. This allows an attacker to manipulate the SQL query to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

The following is a conceptual example of a malicious SQL statement that an attacker might use to exploit this vulnerability:

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

In this example, the attacker sends a JSON payload with a malicious SQL command that would cause the database to delete the ‘users’ table. Note that this is a conceptual example and the specific exploit would depend on the details of the application’s database schema.

Recommendations for Mitigation

Users are advised to apply the vendor patch as soon as possible to mitigate this vulnerability. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as temporary mitigation. These solutions can help to detect and block SQL injection attacks, but they are not a substitute for patching the underlying vulnerability.
