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

The vulnerability lies in the ‘CreateLog’ method used internally by the application. An attacker who has network access and user-level authentication can craft a malicious SQL query that is injected into the application via this method. This allows the attacker to read from and write to the application’s database, bypassing the intended authorization controls. In a successful attack, the attacker could potentially execute code with “NT AUTHORITYNetworkService” permissions and compromise the system.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could look like this:

POST /CreateLog HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer authenticated_user_token
{ "log_entry": "valid_log_entry'; DROP TABLE users; --" }

In this example, the “log_entry” field is supposed to contain a regular log entry. However, an attacker inserts a valid log entry followed by a semicolon and then a SQL command to drop the ‘users‘ table. The ‘–‘ at the end is a comment marker in SQL, which makes the application ignore anything that follows, ensuring that the malicious SQL command is executed.

Recommended Mitigation

Users of the affected versions of TeleControl Server Basic are strongly urged to apply the vendor patch to update the software to version V3.1.2.2 or later. In situations where immediate patching is not possible or feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide a temporary mitigation by detecting and blocking SQL injection attacks.

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

The vulnerability lies in the GetSettings method, which is used internally by the TeleControl Server Basic application. An attacker can exploit this weakness by injecting SQL commands into the data input of this method.
This allows a remote attacker, with authenticated access, to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions. The only precondition for the attacker is to have access to the port 8000 on a system where a vulnerable version of the affected application is running.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit this vulnerability:

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

In this example, the attacker sends a POST request to the GetSettings endpoint with a malicious payload that includes an SQL command (`DROP TABLE users; –`). This command would delete the users table from the database if executed.

Recommended Mitigation Strategy

The best way to prevent this vulnerability is to apply the vendor patch as soon as it becomes available. If this is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking SQL injection attempts.
It is also good practice to ensure that applications like TeleControl Server Basic are not accessible from the internet or untrusted networks, reducing the attack surface.
Finally, businesses should review their application and database permissions, ensuring that they follow the principle of least privilege. This means that each user and application should only have the minimum permissions necessary to perform their function. This can limit the potential impact of this and other similar vulnerabilities.

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

The vulnerability exists due to insufficient sanitization of user-supplied inputs in the ‘UnlockTraceLevelSettings’ method of the TeleControl Server Basic application. An attacker can exploit this vulnerability by sending specially crafted SQL commands to the application via the network on port 8000. Upon successful exploitation, the attacker can read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions, thereby bypassing authorization controls.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP request sent to the vulnerable server:

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

In this example, the attacker is using a classic SQL injection attack, inputting a payload that would always evaluate as true (OR ‘1’=’1′) and then appending a command to drop the “users” table in the database.

Countermeasures and Mitigation

The best mitigation strategy for this vulnerability is to apply the vendor-released patch, which addresses the issue by properly sanitizing user inputs. If a patch cannot be applied immediately, a temporary workaround would be to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block malicious SQL commands. It’s also recommended to restrict network access to the affected service, limiting it to trusted and necessary IP addresses only.

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

The exploit takes advantage of the vulnerable ‘LockTraceLevelSettings’ method in the TeleControl Server Basic application. An authenticated remote attacker can send specially crafted SQL commands in requests to this method. Since the application doesn’t properly sanitize these requests, the malicious SQL commands can be executed, allowing the attacker to bypass authorization controls, read from and write to the application’s database. The attacker can also potentially execute code with “NT AUTHORITYNetworkService” permissions, which can lead to system compromise.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could look like this:

POST /LockTraceLevelSettings HTTP/1.1
Host: vulnerable-server.example.com
Content-Type: application/x-www-form-urlencoded
param1=value1&param2=' OR '1'='1'; DROP TABLE users; --

In this example, the param2 is using a classic SQL Injection technique. The ‘ OR ‘1’=’1′ part always returns true, effectively bypassing any conditional checks. The ‘; DROP TABLE users; –‘ part then executes a new command to drop the users table, with the — commenting out anything that follows, preventing errors in the SQL query. This is a simple example and actual attacks can be much more complex and damaging.

Mitigation

The recommended mitigation is to apply the vendor patch. The updated version V3.1.2.2 of TeleControl Server Basic fixes this vulnerability. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation. These systems can be configured to detect and block attempts to exploit this vulnerability.

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

This vulnerability stems from the application’s ‘UpdateTraceLevelSettings’ method, which is not properly sanitized for SQL commands. As a result, an authenticated attacker can execute arbitrary SQL commands which can lead to unauthorized access and manipulation of the application’s database. Additionally, the attacker can execute code with “NT AUTHORITYNetworkService” permissions, leading to potential system compromise.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This pseudo SQL injection attack targets the ‘UpdateTraceLevelSettings’ method:

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

In this example, the SQL command ‘DROP TABLE users;’ is injected into the ‘traceLevel’ parameter, which could result in the deletion of the ‘users’ table from the database if executed.

Mitigation Guidance

The most effective mitigation strategy for this vulnerability is to apply the vendor patch that updates TeleControl Server Basic to 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 provide temporary mitigation.
