Assigner: WPScan

Description
The wp-review-slider-pro WordPress plugin before 12.7.12 does not perform a capability check on one of its AJAX handlers, and the nonce protecting it is generated for every visitor, allowing any authenticated user, such as a subscriber, to store arbitrary review content which is later output without escaping on public pages, leading to Stored Cross-Site Scripting.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the wp-review-slider-pro WordPress plugin before version 12.7.12. It occurs because the plugin does not properly check user capabilities for an AJAX handler and uses a weak nonce that is generated for every visitor. This allows any authenticated user, including subscribers, to inject malicious scripts into review content. These scripts are then stored and executed when the content is displayed on public pages.

Detection Guidance

Check the installed version of the wp-review-slider-pro plugin. If it is below 12.7.12, the system is vulnerable. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files directly.

Impact Analysis

This vulnerability can allow attackers to inject malicious scripts into your website through user reviews. These scripts can steal user data, hijack sessions, or deface your site. Since any authenticated user can exploit it, even low-privilege users like subscribers pose a risk. The impact includes potential data breaches, loss of user trust, and disruption of website functionality.

Compliance Impact

This vulnerability can lead to non-compliance with GDPR and HIPAA by exposing user data to unauthorized access or theft. GDPR requires protecting user data, and a breach could result in fines. HIPAA mandates safeguarding protected health information, and this flaw could allow unauthorized access to such data, violating compliance requirements.

Mitigation Strategies

Update the wp-review-slider-pro plugin to version 12.7.12 or later immediately. If updating is not possible, consider disabling the plugin temporarily until a patch is applied.
