Stored or persistent cross-site scripting (XSS) is a type of XSS where the attacker first sends the payload to the web application, then the application saves the payload (e.g., in a database or server-side text files), and finally, the application unintentionally executes the payload for every victim visiting its web pages.

Axigen Mail Server before 10.5.57 allows stored Cross-Site Scripting (XSS) in the handling of the timeFormat account preference parameter. Attackers can exploit this by deploying a multi-stage attack. In the first stage, a malicious JavaScript payload is injected into the timeFormat preference by exploiting a separate vulnerability or using compromised credentials. In the second stage, when the victim logs into the WebMail interface, the unsanitized timeFormat value is loaded from storage and inserted into the DOM, causing the injected script to execute.

The description of the plugin has also been updated with a security warning as upload of such content is intended.

Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, `Rack::Directory` generates an HTML directory index where each file entry is rendered as a clickable link. If a file exists on disk whose basename starts with the `javascript:` scheme (e.g. `javascript:alert(1)`), the generated index contains an anchor whose `href` is exactly `javascript:alert(1)`. Clicking the entry executes JavaScript in the browser (demonstrated with `alert(1)`). Versions 2.2.22, 3.1.20, and 3.2.5 fix the issue.
