ZIP Code Based Content Protection SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the ZIP Code Based Content Protection plugin for WordPress, affecting all versions through 1.0.2. The vulnerability arises from inadequate escaping of user-supplied data in the 'zipcode' parameter, allowing unauthenticated attackers 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 SQL injection, where attackers can manipulate database queries to extract or potentially modify sensitive information.

Reproduction

To reproduce this vulnerability, send a request to the WordPress site with the 'zipcode' parameter. The injected SQL code can be appended to manipulate the database query, taking advantage of the lack of proper input sanitization.

Remediation

Users are advised to update the ZIP Code Based Content Protection plugin to version 1.0.3 or later.
