Technical details
The cloud_manage daemon polls a vendor endpoint over plaintext HTTP and passes unsanitized JSON fields from the server response to popen(), enabling OS command injection. An on-path attacker can answer the heartbeat request with a crafted diagnoseParameter value containing shell metacharacters to execute commands as root. No authentication (TLS, certificate pinning, command signing) protects the channel. The vulnerability requires network adjacency and the ability to intercept or redirect HTTP traffic.
