What the vulnerability does
The Jabbernotification plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the admin.php PATH_INFO in all versions up to, and including, 0.99-RC2 due to insufficient input sanitization and output escaping. 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
Jabbernotification versions up to 0.99-RC2 contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts. An attacker can craft a malicious link or page that, when visited by a site user, executes arbitrary JavaScript in the user's browser. This can lead to session hijacking, credential theft, or defacement.
What an attacker can do
Inject and execute malicious JavaScript in a user's browser when they visit a crafted page or link.
Potential impact on your site
Users visiting malicious links could have their sessions hijacked, credentials stolen, or see defaced content.
Conditions required to exploit
A site user must visit a malicious link or page crafted by the attacker; no authentication required.
