Overview
The cybersecurity world is facing a new challenge in the form of CVE-2025-32836, a severe SQL Injection vulnerability that affects all versions of TeleControl Server Basic prior to V3.1.2.2. This vulnerability could potentially lead to system compromise or data leakage, making it a significant threat to organizations utilizing this software. Its severity is further underpinned by its CVSS score of 8.8, indicating a high level of risk.
SQL injection attacks have long been a thorn in the side of cybersecurity professionals. They are a type of code injection attack that can occur when an attacker is able to insert malicious SQL statements into an entry field for execution. The CVE-2025-32836 vulnerability presents an alarming twist to the standard SQL injection attack, as it allows an authenticated remote attacker to bypass authorization controls, read from and write to the application’s database, and execute code with “NT AUTHORITYNetworkService” permissions.
Vulnerability Summary
CVE ID: CVE-2025-32836
Severity: High (CVSS: 8.8)
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
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
For this exploit to work, the attacker needs to gain network access to the targeted system where a vulnerable version of the TeleControl Server Basic application is running. The attacker then takes advantage of the ‘GetConnectionVariables’ method used internally by the application to perform SQL injection.
By injecting malicious SQL code, the attacker can bypass authorization controls, read from, and write to the application’s database. This could potentially allow the attacker to manipulate data, disclose sensitive information, or even execute code with “NT AUTHORITYNetworkService” permissions, leading to a potential system compromise.
Conceptual Example Code
The following is a conceptual representation of a HTTP POST request that an attacker might make to exploit this vulnerability.
POST /GetConnectionVariables HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"database": "targetDB",
"query": "SELECT * FROM users; DROP TABLE users;"
}In this example, the “query” field contains a malicious SQL command that returns all users from the “users” table and then deletes the table.
Please note that this is a conceptual example and the actual malicious SQL commands and the way they are injected can vary based on the specific structure and security measures of the target database.
Recommended Mitigation Measures
The best way to mitigate this vulnerability is by applying the vendor patch to upgrade the TeleControl Server Basic application to version V3.1.2.2 or later. In case this is not possible immediately, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can serve as a temporary measure to help detect and block potential attacks exploiting this vulnerability.
