Descriptions

Red Hat 3scale (aka RH-3scale) API Management Platform (AMP) before 2.0.0 would permit creation of an access token without a client secret. An attacker could use this flaw to circumvent authentication controls and gain access to restricted APIs. NOTE: some sources have a typo in which CVE-2017-7512 maps to an OpenVPN vulnerability. The proper CVE ID for that OpenVPN vulnerability is CVE-2017-7521. Specifically, CVE-2017-7521 is the correct CVE ID for TWO closely related findings in OpenVPN. Any source that lists BOTH CVE-2017-7512 and CVE-2017-7521 for OpenVPN should have listed ONLY CVE-2017-7521.

La plataforma de administración de API (AMP) de 3scale (aka RH-3scale) anterior a la versión 2.0.0 de Red Hat, permitiría la creación de un token de acceso sin un secreto de cliente. Un atacante podría utilizar este fallo para omitir los controles de autenticación y conseguir acceso a las API restringidas. NOTA: algunas fuentes tienen un error tipográfico en que el CVE-2017-7512 se relaciona con una vulnerabilidad de OpenVPN. El ID de CVE adecuado para esa vulnerabilidad de OpenVPN es CVE-2017-7521. Específicamente, CVE-2017-7521 es el ID de CVE correcto para DOS hallazgos estrechamente relacionados en OpenVPN. Cualquier fuente que enumere AMBOS CVE-2017-7512 y CVE-2017-7521 para OpenVPN debe haber enumerado SOLAMENTE CVE-2017-7521.

It was found that RH-3scale AMP would permit creation of an access token without a client secret. An attacker could use this flaw to circumvent authentication controls and gain access to restricted APIs.
