AnalysisAIv1 – Mar 12, 2026

eNet Smart Home server versions 2.2.1 and 2.3.1 allow authenticated users to delete arbitrary user accounts through an authorization bypass in the deleteUserAccount JSON-RPC method. Any low-privileged user can submit a crafted request to remove other accounts without elevated permissions, and public exploit code exists for this vulnerability. The impact includes unauthorized account deletion and potential denial of service, with no patch currently available.

Technical ContextAI · show details

Classified as CWE-862 (Missing Authorization). Affects Enet Smart Home. eNet SMART HOME server 2.2.1 and 2.3.1 contains a missing authorization vulnerability in the deleteUserAccount JSON-RPC method that permits any authenticated low-privileged user (UG_USER) to delete arbitrary user accounts, except for the built-in admin account. The application does not enforce role-based access control on this function, allowing a standard user to submit a crafted POST request to /jsonrpc/management specifying another username to have that account removed without elevated permis

DescriptionCVE.org

eNet SMART HOME server 2.2.1 and 2.3.1 contains a missing authorization vulnerability in the deleteUserAccount JSON-RPC method that permits any authenticated low-privileged user (UG_USER) to delete arbitrary user accounts, except for the built-in admin account. The application does not enforce role-based access control on this function, allowing a standard user to submit a crafted POST request to /jsonrpc/management specifying another username to have that account removed without elevated permissions or additional confirmation.

Executive ViewAI

Why It Matters

eNet SMART HOME servers (versions 2.2.1 and 2.3.1) contain a critical authorization flaw allowing any low-privilege user to delete other user accounts without permission. This enables account hijacking, denial of service, and potential lateral movement within connected smart home environments. Organizations running affected versions face immediate risk of user account manipulation and operational disruption.

Business Impact: High

Compensating Controls

Implement WAF rules to block or log deleteUserAccount JSON-RPC method calls from non-administrative users. Restrict network access to SMART HOME server API endpoints to authorized administrative IP ranges only. Disable the deleteUserAccount feature entirely if not required for operations. Monitor JSON-RPC method logs for suspicious deleteUserAccount activity. Enforce multi-factor authentication for all user accounts to limit lateral movement impact.
