CVE-2024-23784

Credential disclosure via unrestricted management page

Published Feb 14, 2024 · Updated Mar 25, 2025

Improper access control in Sharp Cloud-based Energy Controller B0.1.9.1 and earlier allows remote attackers to read login credentials. The management page displays a username and its hashed password without enforcing the intended access restriction, although no deeper implementation details are public. Attackers need no account but must share the appliance's network, and the direct consequence is disclosure of the displayed username and password hash.
