Overview
The world of cybersecurity is constantly evolving, and with it, the threats that organizations face. One such threat has recently been identified in the TeleControl Server Basic application (all versions preceding V3.1.2.2). Dubbed as CVE-2025-31350, this vulnerability exposes the application to SQL injection attacks, giving potential attackers the power to bypass authorization controls, manipulate the application’s database, and execute code with elevated permissions.
This vulnerability is not to be taken lightly. It has far-reaching implications for businesses using the affected TeleControl Server Basic versions, as it opens the door to potential system compromise or data leakage. Given the severity of the threat, it’s imperative that organizations take immediate measures to mitigate the risk.
Vulnerability Summary
CVE ID: CVE-2025-31350
Severity: Critical (8.8 CVSS score)
Attack Vector: Network
Privileges Required: Low (Authenticated Remote Access)
User Interaction: None
Impact: Potential system compromise or data leakage
Affected Products
Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The exploit takes advantage of the ‘UpdateBufferingSettings’ method, a feature of the TeleControl Server Basic application, which is vulnerable to SQL injection. An attacker who has authenticated remote access can send specially crafted SQL queries to manipulate the application’s database. This can lead to bypassing authorization controls, data leakage, or even potential system compromise. The attack can be performed remotely, provided the attacker has access to port 8000 on a system where a vulnerable version of the affected application is running.
Conceptual Example Code
A conceptual example of how the vulnerability might be exploited could be a SQL injection attack embedded in a HTTP request, like the following:
POST /UpdateBufferingSettings HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "bufferSettings": "'; DROP TABLE users; --" }In the above example, a seemingly innocuous request to update buffering settings is used as a cover to execute a malicious SQL command (`DROP TABLE users`). If successful, this would delete the ‘users’ table from the application’s database, leading to a significant data loss.
Mitigation Guidance
Users of affected versions of TeleControl Server Basic are advised to apply the vendor patch, which resolves the vulnerability in the ‘UpdateBufferingSettings’ method. In the absence of a patch, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation, helping to identify and block attempted SQL injection attacks.
