Description:

Last Month I reported SQL Injection vulnerabilities in www.ebay.com sub domains. You can see how many days they took for patching & allowing me to publish the vulnerability. But finally they fixed it & listed me in their Researchers Acknowledgement Page.Like every other bounty hunter I was also searching for some vulnerability in EBAY.That time I have no idea that Ebay don’t give bounty for any vulnerability. Not even for SQL Injection. :)

POC:

Sub Domains:  http://sea.ebay.com & http://export.ebay.co.th/

Page:
http://sea.ebay.com/searchAnnoucement.php
http://export.ebay.co.th/searchAnnoucement.php

Vulnerable Parameter: “checkbox” Array POST parameter.

Search option in above pages provides a “Select Site” checkboxes which filters the search result by different countries.
