Unauthenticated seller access via manipulated Name argument
Published Sep 8, 2026 · Updated Sep 8, 2026
Improper authentication in Aircheng iWebShop 5.0 through 5.15 allows remote attackers to access seller functions through the login endpoint. The Login function in controllers/systemseller.php processes an attacker-controlled Name argument without correctly authenticating the associated seller account. No credentials or user interaction are required, and exploitation permits limited reading, modification, and service interruption through seller functionality.
