Within the helpdesk utility usd250, an XSS in the comments field is possible.

The comments strip script tags and replace them with (not allowed), but

script tags dont need to be in place for XSS. Something along the lines of...

<b onmouseover="window.alert('omghax')">some text</b> Suffices.

The fix is to use htmlentities() or htmlspecialchars() to filter ALL html

from user input.
