Subject:	Cross-Site Scripting vulnerability in eCaptcha

Hello Bugtraq!

I want to warn you about Cross-Site Scripting vulnerability in eCaptcha
(plugin for E107). I found this hole in July 2008 and disclosed it at
25.09.2008.

XSS:

POST query at page
http://site/path/ecaptcha/?key=b7c9bf99e763252105f047a5ca5681d0

<script>alert(document.cookie)</script>
in field: Type Here.

Working key (ecaptcha_key) is required, which can be retrieved by script.
Every key works only for one time.

Exploit:

(http://websecurity.com.ua/2253/).
