CVE-2018-25333 Unknown Vendor CVE debrief

Who should care

Operators, maintainers, and security teams responsible for Nordex N149/4.0-4.5 Wind Turbine Web Server 4.0 deployments should prioritize this issue, especially if the login interface is reachable from trusted or untrusted networks. Asset owners who manage industrial or operational web interfaces should also review exposure and logging around authentication endpoints.

Technical summary

The NVD record describes a SQL injection vulnerability in login.php, specifically in the login parameter. The weakness is classified as CWE-89. Based on the provided record, exploitation requires only crafted network requests and no authentication, which can allow arbitrary SQL queries against the backend database and may support authentication bypass or sensitive data extraction. No patch details, exploit steps, or confirmed remediation advisory were included in the supplied corpus.

Defensive priority

High. This is an unauthenticated network-reachable database injection in a login endpoint, which makes it a strong candidate for urgent exposure review and compensating controls, even though vendor patch status is not provided in the supplied material.

Recommended defensive actions

• Inventory all Nordex N149/4.0-4.5 Wind Turbine Web Server 4.0 instances and confirm whether the login endpoint is exposed beyond required management networks.
• Restrict access to the web server to trusted administrative networks and remove any unnecessary internet or broad internal exposure.
• Apply vendor guidance or firmware/software updates if available from the product owner or maintainer.
• Review application code or vendor configuration for parameterized database queries and proper server-side input validation on login.php.
• Inspect authentication and database logs for anomalous POST requests, failed logins, unusual SQL errors, or unexpected data access patterns.
• Rotate credentials and review database permissions if there is any indication the login endpoint was abused.
• Validate that monitoring and alerting cover the login path and backend database activity for this device or service.

Evidence notes

The supplied NVD record for CVE-2018-25333 states that the affected product is Nordex N149/4.0-4.5 Wind Turbine Web Server 4.0 and that the issue is an SQL injection through the login parameter in login.php. The record also identifies CWE-89 and includes references to Nordex Online, Exploit-DB, and a VulnCheck advisory. Vendor attribution in the supplied enrichment is marked low confidence and needs review, so the product/vendor naming should be treated cautiously beyond the text of the record itself.
