CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a Blind SQL injection vulnerability in Windu CMS version 4.1. It allows a remote unauthenticated attacker to inject SQL syntax into the URL path via an HTTP header, enabling Blind SQL Injection attacks.

Detection Guidance

To detect Blind SQL injection in Windu CMS, monitor HTTP headers and URL paths for suspicious SQL syntax like single quotes, semicolons, or SQL keywords (e.g., UNION, SELECT). Use tools like SQLmap with commands such as: sqlmap -u "http://target-url/path" --headers="Header-Name: value'" --batch --level=5 --risk=3. Check web server logs for unusual query patterns or errors.

Impact Analysis

A successful exploit could allow attackers to manipulate the database, potentially accessing, modifying, or deleting sensitive data without authentication. This could lead to unauthorized data exposure or system compromise.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations may face legal penalties, reputational damage, and loss of compliance certifications.

Mitigation Strategies

Immediately update Windu CMS to the latest patched version if available. If no patch exists, implement input validation for HTTP headers and URL paths to block SQL syntax. Use a web application firewall (WAF) to filter malicious requests. Restrict database permissions to limit damage from potential injections.
