What the vulnerability does
The JustClick registration plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in all versions up to, and including, 0.1. This is due to insufficient input sanitization and output escaping on the `PHP_SELF` server variable. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
The JustClick registration plugin versions 0.1 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in users' browsers when they visit affected pages. The vulnerability requires user interaction and can affect other users on the site. Update to a version newer than 0.1 to resolve this issue.
What an attacker can do
Inject malicious scripts that run in users' browsers and steal session data or perform actions on their behalf.
Potential impact on your site
Users visiting affected pages may have their sessions compromised or be redirected to malicious sites.
Conditions required to exploit
Victim must visit a page containing the attacker's malicious link or content; no authentication required.
