Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows a low-privileged user to trick the system into giving them administrative access, letting them change device settings and control the entire smart home system. To exploit this, the attacker just needs to send a specially crafted request to the server, without needing any special permissions.

Technical Description

eNet SMART HOME server 2.2.1 and 2.3.1 contains a privilege escalation vulnerability due to insufficient authorization checks in the setUserGroup JSON-RPC method. A low-privileged user (UG_USER) can send a crafted POST request to /jsonrpc/management specifying their own username to elevate their account to the UG_ADMIN group, bypassing intended access controls and gaining administrative capabilities such as modifying device configurations, network settings, and other smart home system functions.
