CVE-2018-8119

TITLE

plural Azure IoT SDK Impersonation vulnerability in products

Trust: 0.8

sources: JVNDB: JVNDB-2018-005095

DESCRIPTION

A spoofing vulnerability exists when the Azure IoT Device Provisioning AMQP Transport library improperly validates certificates over the AMQP protocol, aka "Azure IoT SDK Spoofing Vulnerability." This affects C# SDK, C SDK, Java SDK. Microsoft C #, C, and Java SDK for Azure IoT are software development kits for Microsoft Azure (Microsoft) based on C #, C, and Java languages for developing Azure IoT (Internet of Things Platform) applications, respectively. An attacker could use this vulnerability to impersonate a server. Multiple Microsoft Azure IoT SDKs are prone to a security vulnerability that may allow attackers to conduct spoofing attacks. A man-in-the-middle attacker can exploit this issue to conduct spoofing attacks and perform unauthorized actions; other attacks are also possible
