WordPress Image Gallery Plugin Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the Image Gallery – Responsive Photo Gallery plugin for WordPress, affecting all versions through 1.0.5. The vulnerability arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts via the 'awsmgallery' parameter. These scripts could be executed if the attacker successfully persuades a user to click on a manipulated link.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject malicious scripts that are executed in the context of the user's browser.

Reproduction

To reproduce this vulnerability, send a request to a page that includes the 'awsmgallery' parameter with injected script content. Ensure that the input is not properly sanitized or escaped, allowing the script to execute when the link is clicked.

Remediation

Users are advised to update the Image Gallery – Responsive Photo Gallery plugin to version 2.1 or later.
