Joomla Extension - phoca.cz - Authorisation bypass through user-controlled key (IDOR) in Order View in Phoca Cart 5.0.0 - 6.1.8 - Phoca Cart's order-file download endpoint does not verify the download tokens it asks for. The d (download token) and o (order token) parameters are checked for non-emptiness only — they are never compared to the stored download_token / order_token values. As a result, any remote user (including a guest with no account at all) can download any customer's digital goods by enumerating sequential id values and supplying arbitrary non-empty tokens.
