Overview
The cybersecurity community has recently identified a significant vulnerability in TeleControl Server Basic, a widely used server control application. This vulnerability, designated as CVE-2025-32862, is a SQL injection flaw that impacts all versions of the application prior to V3.1.2.2. This vulnerability matters because it can enable an authenticated remote attacker to bypass authorization controls, interact with the application’s database, and potentially execute code with “NT AUTHORITYNetworkService” permissions. The potential impact of this vulnerability includes system compromise and data leakage, which underscores the importance of immediate mitigation.
Vulnerability Summary
CVE ID: CVE-2025-32862
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise and potential data leakage
Affected Products
No phone number, email, or personal info required.
Product | Affected Versions
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 AUTHORITY\NetworkService” 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¶m2=' 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.
