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 


in field: Type Here.

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

Exploit:

I mentioned about this vulnerability at my site 
(http://websecurity.com.ua/2253/). 

Best wishes & regards,
