Vulnerability Spotlight: Multiple Vulnerabilities in Yi Technology Home Camera

Summary: Cisco Talos disclosed vulnerabilities in the Yi Technology Home Camera 27US firmware version 1.8.7.0D, with five of them reachable over the network and the rest requiring physical access. The most severe, TALOS-2018-0567, needs only the ability to respond to the camera's frequent time_sync HTTP request to achieve command injection and code execution, and all network-based issues are enabled by cleartext UDP and HTTP traffic described in TALOS-2018-0616.

Bottom line: A camera that syncs time over unencrypted HTTP the moment it joins the network hands an attacker on the path a command injection route to code execution, and a single sniffed token (TALOS-2018-0601) grants owner-level p2p_tnp API access until the device reboots.
