CVE-2022-4321 Scanner

PDF Generator for WordPress is a plugin designed to allow WordPress site administrators and users to easily create PDF documents from their content. This plugin is used by a wide range of websites, from blogs and portfolios to e-commerce and corporate sites, to offer visitors downloadable PDF versions of posts, pages, or custom post types. It is particularly useful for providing users with offline or printable versions of web content, enhancing accessibility and user engagement. The functionality it offers makes it a popular choice for content creators looking to extend the versatility and reach of their digital content.

The Cross-Site Scripting (XSS) vulnerability in PDF Generator for WordPress plugin versions before 1.1.2 is caused by insufficient input sanitization in a vendored dompdf example file. This vulnerability can be exploited by an attacker by crafting malicious links that include JavaScript code. If clicked by a user with high privileges, such as an admin, the code would execute within the context of the user's browser. This could lead to unauthorized actions being performed, data theft, or the injection of further malicious scripts.

Specifically, the vulnerability resides in the inclusion of an example file from the dompdf library used by the plugin. This file, Query.php, improperly handles user input via the 'keyword' GET parameter, allowing for the injection of arbitrary HTML and script code into the web page. This makes it possible for attackers to execute malicious scripts in the browser of anyone who clicks on a specially crafted link. The reflected nature of the attack requires the victim to interact with the malicious link, which can be facilitated through phishing or other social engineering techniques.

Exploiting this vulnerability could lead to a range of adverse effects including the theft of authentication cookies, session hijacking, redirecting users to malicious sites, or even performing actions on the website as the victim. For administrators, this could mean unauthorized access to sensitive areas of the site, changes to website content, or exposure of user data. The impact is especially critical due to the potential for exploiting high-privilege users, leading to a complete compromise of the site.
