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

An attacker who is able to authenticate and gain access to port 8000 on a system running a vulnerable version of the TeleControl Server Basic software can exploit this vulnerability. By injecting malicious SQL code through the ‘LockDatabaseSettings’ method, the attacker can 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 how an attacker might exploit this vulnerability. This is a pseudocode representation of how a malicious SQL query might be sent via an HTTP POST request:

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

In this example, the `settingsLock` parameter is being used to inject a SQL command (`DROP TABLE users;`) that could lead to destructive actions on the database.

Recommendations for Mitigation

The best course of action to mitigate this vulnerability is to apply the latest patch from the vendor. The patch addresses the SQL injection vulnerability in the ‘LockDatabaseSettings’ method and should be applied as soon as possible. For temporary mitigation or added security, a WAF (Web Application Firewall) or IDS (Intrusion Detection System) could be used to detect and block attempts at SQL injection. However, these are only temporary solutions and do not replace the need for patching the software.

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

The vulnerability resides in the ‘UnlockTcmSettings’ method used internally by the application. An attacker who has gained authenticated access to the system can inject malicious SQL commands, exploiting this flaw. This attack, if successful, allows the attacker to bypass authorization controls, leading to unauthorized access to the application’s database. With this access, the attacker can read from and write to the database, and execute code with “NT AUTHORITYNetworkService” permissions. For this attack to be successful, the attacker needs access to port 8000 on a system where a vulnerable version of the application is being executed.

Conceptual Example Code

An example of how this vulnerability might be exploited is shown below. This is a conceptual example and does not represent a real SQL injection attack.

POST /UnlockTcmSettings HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Basic base64credentials
{
"settings": "'; DROP TABLE users;--"
}

In this example, the attacker sends a malicious payload that, if executed, could result in dropping the “users” table from the database.

Mitigation Guidance

To mitigate this vulnerability, users of the affected TeleControl Server Basic versions are advised to apply a vendor patch. If the patch is not available or cannot be applied immediately, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as a temporary mitigation measure. It is crucial always to keep software up-to-date and regularly monitor systems for unusual activity to minimize the impact of such vulnerabilities.

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

The vulnerability resides in the ‘UnlockSmtpSettings’ method used internally by the TeleControl Server Basic. This method is susceptible to SQL injection, a common attack technique where an attacker inserts malicious SQL code into a query. This can manipulate the application’s database, leading to unauthorized access and potential data leakage. In this case, a successful SQL injection attack could allow an attacker to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

A conceptual use case for exploiting this vulnerability might involve an HTTP request to the vulnerable endpoint with a malicious payload. This is represented in the following pseudocode:

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

In this hypothetical example, the malicious payload is a SQL command that would delete the user’s table from the database. This is a textbook example of SQL injection, and while this specific payload may not be the exact method an attacker would use to exploit CVE-2025-32849, it illustrates the potential severity of this vulnerability.

Mitigation Guidance

To mitigate the risks associated with this vulnerability, users are advised to apply the vendor patch, which should upgrade the TeleControl Server Basic to version V3.1.2.2 or higher. In the absence of a patch, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation. It is crucial to keep all software updated to the latest version and to regularly monitor systems for any signs of unauthorized access.

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

The vulnerability exists due to inadequate input sanitization in the ‘LockSmtpSettings’ method, which is used internally by the application. An attacker who sends carefully crafted SQL code as part of their input to this function can trigger an SQL injection attack. This would allow them to manipulate the database, including reading from and writing to it, and potentially executing code with “NT AUTHORITYNetworkService” permissions.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP request, shell command, or pseudocode.

POST /LockSmtpSettings HTTP/1.1
Host: target.example.com:8000
Content-Type: application/x-www-form-urlencoded
smtpSettings='; DROP TABLE users; --

In this example, the attacker sends a malicious SQL command (`DROP TABLE users`) which would effectively delete the entire ‘users’ table from the database, if executed. The `–` at the end of the command is an SQL comment, causing the database server to ignore the rest of the original query, preventing syntax errors.

Mitigation

Users of affected versions of TeleControl Server Basic are advised to update to version V3.1.2.2 or later as soon as possible to address this vulnerability. If an immediate update is not possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure is recommended. These systems should be configured to detect and block SQL Injection attacks.

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

The vulnerability exists in the ‘UnlockGeneralSettings’ method internally used by the TeleControl Server Basic. This method is susceptible to SQL injection, a common technique where an attacker inserts malicious SQL code into a query. The attacker can exploit this vulnerability if they have authenticated access to the system and can reach port 8000, where the affected application is executed.
Once the malicious SQL code is injected, the attacker can manipulate the application’s database. This includes reading from and writing to the database, which could lead to unauthorized access to sensitive information, and executing code with “NT AUTHORITYNetworkService” permissions, potentially compromising the entire system.

Conceptual Example Code

The following is a conceptual representation of how an attacker might exploit this vulnerability. In this example, the attacker sends a malicious SQL command through an HTTP POST request.

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

In this example, the attacker is attempting to delete the ‘users’ table from the database. The query will unlock the settings, and then proceed to execute the malicious SQL command due to improper input sanitization.
