Subject: Ebay seller information feedback can be forged with Javascript

Hi FD,

The German news channel ARD reports [1] that Ebay's seller information
feedback feature can be modified at will by sellers to influence their
credentials.

According to the ARD a seller uploads a Javascript along with his
description that replaces any real feedback information with faked
feedback inside the viewers browser. The ARD recommends to deactivate
Javascript when doing business at Ebay. According to the ARD, Ebay knows
about this problem but hasn't acted yet.

regards,
Tobias W.
