CVE-2022-4295 Scanner Detail

The Show all comments plugin for WordPress is designed to allow website administrators to display all comments on their site in a single page. It's particularly useful for sites that receive a high volume of comments, as it simplifies management and moderation for site administrators. This plugin is widely used across various WordPress websites, including blogs, news sites, and e-commerce platforms, to enhance user engagement and interaction. Developed by AppJetty, it aims to provide a more streamlined experience for both site visitors and administrators by aggregating comments in an easily accessible format.

A Reflected Cross-Site Scripting (XSS) vulnerability exists in versions of the Show all comments WordPress plugin prior to 7.0.1. This issue arises due to insufficient sanitization and escaping of user-supplied input before it is output back into the page. As a result, attackers can inject arbitrary script code into the web page viewed by other users, including administrators. This vulnerability can be exploited to execute malicious scripts in the context of the victim's browser, potentially leading to unauthorized actions and data access.

The vulnerability specifically exists within the `sac_post_type_call` AJAX action, where the `post_type` parameter is not properly sanitized before being echoed back to the user. By crafting a malicious URL that includes script tags within the `post_type` parameter, an attacker can trigger the execution of arbitrary JavaScript code in the context of the user's browser session. This particularly affects logged-in users with high privileges, such as site administrators, making it possible for attackers to perform a wide range of malicious activities.

Successful exploitation of this XSS vulnerability can lead to several security issues, including session hijacking, where attackers gain control over victims' sessions; website defacement, where the appearance of the site is altered; and theft of sensitive information. For administrators, this could mean unauthorized access to administrative functions, modification of site content, and exposure of confidential data.
