Squirrly SEO WordPress Plugin Blind SQL Injection Vulnerability

A blind SQL injection vulnerability has been identified in the Squirrly SEO plugin for WordPress, affecting all versions through 12.4.05. The vulnerability arises from inadequate escaping of user-supplied data in the 'search' parameter, allowing authenticated attackers with Subscriber-level access or higher to inject additional SQL queries. This exploitation could lead to unauthorized access to sensitive information within the database.

Impact

Exploitation of this vulnerability allows for blind SQL injection, where an attacker can manipulate SQL queries and potentially extract sensitive data from the database.

Reproduction

To reproduce this vulnerability, an authenticated user with Subscriber-level access or higher can send a request to the WordPress site with the 'search' parameter. The lack of proper input sanitization allows for the injection of malicious SQL code, which is executed by the database. This can be done through various entry points in the plugin that utilize the 'search' parameter without adequate protection.

Remediation

Users are advised to update the Squirrly SEO plugin to version 12.4.06 or later, where this vulnerability has been patched.
