Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The vulnerability lies within the ‘CreateBackup’ method, a feature used internally by the TeleControl Server Basic. This method is susceptible to SQL injection, a common web application flaw.
An attacker can craft a malicious SQL query that manipulates the application’s database, allowing the attacker to bypass authorization controls. The attacker can then read from and write to the database, and even execute code with “NT AUTHORITYNetworkService” permissions.
This vulnerability is exploitable remotely, and only requires the attacker to have access to port 8000 on a system running a vulnerable version of TeleControl Server Basic.
Conceptual Example Code
Below is an example of how the SQL injection vulnerability might be exploited:
POST /CreateBackup HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{ "backupName": "'; DROP TABLE users; --" }
In this hypothetical example, the attacker is attempting to delete the ‘users’ table from the database. The “;” character is used to end the current SQL command, and the “–” sequence is a SQL comment, effectively ignoring the remainder of the original query.
Mitigation and Prevention
As a temporary mitigation strategy, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to block or alert on suspicious activity. However, these measures do not resolve the underlying vulnerability.
For a comprehensive solution, users should apply the latest patch provided by the vendor as soon as possible. This patch addresses the vulnerability by ensuring that all inputs are properly sanitized, thereby preventing SQL injection attacks.
