Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The vulnerability stems from the ‘LockProjectCrossCommunications’ method used internally within the application. This method is vulnerable to SQL injection, a type of attack where an attacker inserts malicious SQL code into an entry field for execution. If successfully exploited, the attacker can manipulate the application’s database, read and write data, and even execute code with “NT AUTHORITYNetworkService” permissions. This exploit requires access to port 8000 on a system where a vulnerable version of the affected application is running.
Conceptual Example Code
Below is a conceptual example of how an SQL injection exploit might be carried out against the vulnerable ‘LockProjectCrossCommunications’ method:
POST /LockProjectCrossCommunications HTTP/1.1
Host: target.example.com
Content-Type: application/sql
{ "project_id": "1; DROP TABLE users;" }In this example, the malicious SQL command `DROP TABLE users;` is inserted into the `project_id` field. If the application is vulnerable and does not properly sanitize user input, this command could potentially be executed against the application’s database, leading to data loss or unauthorized access.
Mitigation
To mitigate this vulnerability, it’s recommended to apply the vendor patch. In case the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Given the severity of this vulnerability, it’s crucial that affected systems are updated as quickly as possible to prevent potential exploitation.
