Vulnerability Overview

The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wp_id' parameter in all versions up to, and including, 4.4.2 due to missing authorization checks on processAction function, as well as insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that will execute whenever a user accesses a wp-admin dashboard.

Technical Analysis

REMEDIATION: Update to version 4.4.3, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
