CVE-2017-6432

Status: ModifiedHigh (8.1)—

An issue was discovered on Dahua DHI-HCVR7216A-S3 3.210.0001.10 build 2016-06-06 devices. The Dahua DVR Protocol, which operates on TCP Port 37777, is an unencrypted, binary protocol. Performing a Man-in-the-Middle attack allows both sniffing and injections of packets, which allows creation of fully privileged new users, in addition to capture of sensitive information.

CVSS
