✍️ Description

GET parameter ?plugin= of plugin.php is vulnerable to reflected cross site scripting. plugin.php sends unvalidated data to a web browser, which can result in the browser executing malicious code. In this case the data is sent at printf() in plugin.php

🕵️‍♂️ Proof of Concept

1. Visit /plugin.php?plugin=</script><script>alert(1)&page= and XSS will be pop up.

💥 Impact

The attacker can:

Perform any action within the application that the user can perform. View any information that the user is able to view. Modify any information that the user is able to modify. Initiate interactions with other application users, including malicious attacks, that will appear to originate from the initial victim user.
