Overview
The cybersecurity landscape is constantly evolving with new threats and vulnerabilities being discovered on an ongoing basis. One such recent discovery is the CVE-2025-32863 vulnerability, affecting all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability is a critical issue that can potentially expose sensitive data or even compromise the entire system. It is particularly concerning as it allows an authenticated remote attacker to bypass security controls and gain unauthorized access to the application’s database.
This vulnerability is significant due to the potential impact on organizations using the affected application, especially those in critical infrastructure sectors where such a breach could have far-reaching consequences. It highlights the need for proactive security measures and regular vulnerability assessments to maintain a robust cybersecurity posture.
Vulnerability Summary

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 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 AUTHORITY\NetworkService” 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.
