CVE-2022-1756 Scanner

The Newsletter plugin for WordPress is a powerful tool designed to create, send, and manage emails for site subscriptions directly within WordPress. It is widely used by website owners and marketers to engage with their audience, distribute newsletters, and track subscriber activity. This plugin provides a user-friendly interface for composing emails, managing subscriber lists, and analyzing campaign performance. It is essential for businesses, bloggers, and digital marketers looking to enhance their email marketing efforts and maintain communication with their subscribers. Its integration with WordPress makes it a convenient choice for WordPress site administrators.

The XSS vulnerability in the Newsletter plugin is specifically found in the way the plugin handles the $_SERVER['REQUEST_URI'] parameter on admin pages. The plugin fails to properly sanitize user-supplied input before outputting it back to the user, relying on addslashes() for escaping, which is insufficient to prevent XSS attacks in older browsers. This flaw enables attackers to craft malicious URLs that, when visited by an admin using a vulnerable browser, can lead to the execution of arbitrary JavaScript code in the context of the victim's browser, compromising the security of the session.

If exploited, this XSS vulnerability could allow attackers to steal cookies, session tokens, or other sensitive information from victims. It could also enable attackers to perform actions on behalf of the admin, such as changing plugin settings, sending phishing emails to subscribers, or even compromising the entire website. The impact of this vulnerability is particularly concerning for websites with a large subscriber base or those handling sensitive user information.
