Overview
In today’s post, we’re examining an alarming vulnerability, identified as CVE-2025-32833, found in the TeleControl Server Basic. This vulnerability affects all versions prior to V3.1.2.2. It is a critical flaw as it opens the gate for SQL injection, allowing attackers to manipulate the application’s database and execute malicious code. This vulnerability is particularly significant because it has the potential to compromise the system or leak sensitive data.
Vulnerability Summary
CVE ID: CVE-2025-32833
Severity: High (CVSS: 8.8)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or 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 resides in the ‘UnlockProjectUserRights’ method used internally by the TeleControl Server Basic. This method is susceptible to SQL injection, which is a code injection technique that attackers use to exploit security vulnerabilities in a website’s database layer.
In this case, an authenticated remote attacker can exploit this vulnerability by sending specially crafted requests to the application via port 8000. These requests can manipulate the SQL queries processed by the ‘UnlockProjectUserRights’ method, allowing the attacker to read from and write to the application’s database.
Furthermore, the attacker can execute code with “NT AUTHORITYNetworkService” permissions, bypassing authorization controls. This can lead to a full compromise of the system or leakage of sensitive data.
Conceptual Example Code
Below is a hypothetical example of how an attacker could exploit this vulnerability:
POST /UnlockProjectUserRights HTTP/1.1
Host: vulnerable_server:8000
Content-Type: application/json
{
"user_id": "admin'; DROP TABLE users; --"
}In this example, the attacker uses a SQL injection payload (`”admin’; DROP TABLE users; –“`) to manipulate the SQL query processed by the ‘UnlockProjectUserRights’ method. This payload instructs the database to drop (delete) the users table, resulting in potential data loss.
Please note this is a conceptual representation and actual exploit code may differ.
Mitigation Guidance
As a cybersecurity expert, we recommend applying the vendor patch as soon as possible to mitigate this vulnerability. If the patch cannot be applied immediately, consider using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation.
Always ensure that your systems are up-to-date with the latest security patches and that you follow best practices for secure software development to prevent such vulnerabilities from occurring in the first place.
