Prior to 6.6.10.15 and 6.7.8.1, a vulnerability in the Shopware app registration flow that could, under specific conditions, allow attackers to take over the communication channel between a shop and an app. The legacy app registration flow used HMAC\u2011based authentication without sufficiently binding a shop installation to its original domain. During re\u2011registration, the shop-url could be updated without proving control over the previously registered shop or domain. This made targeted hijacking of app communication feasible if an attacker possessed the relevant app\u2011side secret. By abusing app re\u2011registration, an attacker could redirect app traffic to an attacker\u2011controlled domain and potentially obtain API credentials intended for the legitimate shop. This vulnerability is fixed in 6.6.10.15 and 6.7.8.1."}, {"lang": "es", "value": "Shopware es una plataforma de comercio abierta. Antes de las versiones 6.6.10.15 y 6.7.8.1, una vulnerabilidad en el flujo de registro de aplicaciones de Shopware que podr\u00eda, bajo condiciones espec\u00edficas, permitir a los atacantes tomar el control del canal de comunicaci\u00f3n entre una tienda y una aplicaci\u00f3n. El flujo de registro de aplicaciones heredado utilizaba autenticaci\u00f3n basada en HMAC sin vincular suficientemente una instalaci\u00f3n de tienda a su dominio original. Durante el nuevo registro, la URL de la tienda podr\u00eda actualizarse sin probar el control sobre la tienda o dominio previamente registrado. Esto hizo factible el secuestro dirigido de la comunicaci\u00f3n de la aplicaci\u00f3n si un atacante pose\u00eda el secreto relevante del lado de la aplicaci\u00f3n. Al abusar del nuevo registro de la aplicaci\u00f3n, un atacante podr\u00eda redirigir el tr\u00e1fico de la aplicaci\u00f3n a un dominio controlado por el atacante y potencialmente obtener credenciales de API destinadas a la tienda leg\u00edtima.
