Overview
There is a new security issue in the cybersecurity landscape that is raising concerns among professionals and organizations alike. The issue is a significant vulnerability identified in all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability is of particular interest due to its potential to allow a remote and authenticated attacker to bypass the authorization controls and manipulate the application’s database. The ability to execute code with “NT AUTHORITY\NetworkService” permissions further exacerbates the risk. This vulnerability can potentially cause system compromises or data leakage, making it crucial for cybersecurity professionals to understand and mitigate its impact.
Vulnerability Summary
CVE ID: CVE-2025-29905
Severity: High – 8.8
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise, unauthorized read/write access to the application’s database, 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 vulnerability occurs because of an issue with the ‘RestoreFromBackup’ method used internally by the TeleControl Server Basic application. This method is susceptible to SQL injection attacks, allowing a malicious attacker to bypass the application’s authorization controls. The attacker can then read from and write to the application’s database and execute code with “NT AUTHORITY\NetworkService” permissions. For a successful attack, the attacker must have access to port 8000 on a system where a vulnerable version of the affected application is being executed.
Conceptual Example Code
A potential SQL injection attack exploiting this vulnerability might look conceptually like this:
POST /RestoreFromBackup HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"database_name": "main_db",
"backup_file": "' OR '1'='1'; -- "
}In this example, the attacker is injecting a common SQL injection payload into the `backup_file` parameter. If the application doesn’t properly sanitize inputs, this could allow the attacker to bypass authorization controls and interact directly with the application’s database.
To mitigate this vulnerability, users are advised to apply the vendor patch or use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as a temporary measure. Stay vigilant and ensure that your systems are always updated with the latest security patches to protect against such vulnerabilities.
