Attack-Flow Graph

Executive Summary

The Rank Math SEO WordPress plugin before version 1.0.280 has a flaw in its settings import feature. It fails to properly check the type of files being uploaded, allowing administrators to upload PHP files. These files can then be executed remotely, giving attackers control over the server.

Detection Guidance

Check the installed version of the Rank Math SEO plugin. If it is below 1.0.280, the system is vulnerable. Use WordPress admin panel or run a command like 'wp plugin list' in the WordPress directory to verify the version.

Impact Analysis

If you are an administrator using Rank Math SEO before version 1.0.280, an attacker with administrator access could upload a malicious PHP file. This could lead to full server compromise, unauthorized data access, or further attacks on your WordPress site or network.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and security. Organizations may face legal penalties, reputational damage, and loss of compliance certifications if exploited.

Mitigation Strategies

Update the Rank Math SEO plugin to version 1.0.280 or later immediately. Remove any unauthorized PHP files uploaded via the import feature and review administrator accounts for suspicious activity.
