Description
The Widgets for Google Reviews plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `trustindex` shortcode in all versions up to, and including, 13.2.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Widgets for Google Reviews plugin for WordPress. It occurs via the plugin's 'trustindex' shortcode in all versions up to and including 13.2.1. The problem arises because the plugin does not properly sanitize or escape user-supplied attributes, allowing authenticated users with contributor-level access or higher to inject malicious web scripts. These scripts then execute whenever any user accesses the affected page.

Impact Analysis

An attacker with contributor-level access or higher can exploit this vulnerability to inject arbitrary scripts into pages. This can lead to unauthorized actions such as stealing user credentials, session hijacking, defacement, or spreading malware to users who visit the infected pages. It compromises the integrity and security of the website and its users.

Detection Guidance

Detection of this vulnerability involves identifying the presence of the Widgets for Google Reviews plugin for WordPress at version 13.2.1 or earlier, and checking for usage of the `trustindex` shortcode with potentially malicious input. Since the vulnerability is a Stored Cross-Site Scripting (XSS) via the `trustindex` shortcode, detection can include scanning WordPress pages or posts for suspicious scripts injected via this shortcode. Additionally, monitoring HTTP requests and responses for unusual script content in pages that use this shortcode can help. Specific commands are not provided in the resources, but general approaches include using WordPress CLI to list plugin versions (`wp plugin list`), searching the WordPress database for posts containing the `trustindex` shortcode with suspicious attributes, or using web vulnerability scanners that detect stored XSS in WordPress plugins. [1]

Mitigation Strategies

Immediate mitigation steps include updating the Widgets for Google Reviews plugin to a version later than 13.2.1 where the vulnerability is fixed. If an update is not immediately available, restrict contributor-level and above users from adding or editing content with the `trustindex` shortcode until a patch is applied. Additionally, review and sanitize any existing content using the shortcode to remove injected scripts. Implementing Web Application Firewall (WAF) rules to block malicious script injections targeting this shortcode can also help mitigate exploitation. [1]
