What the vulnerability does
01Description
The Wp Google Places Review Slider plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'place' parameter in versions up to, and including, 18.1. This is due to insufficient input sanitization and output escaping in admin/partials/googlecrawl_dfs.php, where the $_GET['place'] value is URL-decoded, stripslashes()'d, and echoed directly into an HTML value attribute with no esc_attr() call when the supplied place is not already a stored key in the wprev_google_crawls option. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.
Explanation of Vulnerability in Simple Terms
02Summary
WP Google Review Slider versions 18.1 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in visitors' browsers when they view pages containing the plugin's output. The vulnerability requires user interaction—typically a victim visiting a compromised page—and can affect other users on the site. Update to a version newer than 18.1 to resolve this issue.
