CVE-2026-24789Network attack vector

Unauthenticated password change via unprotected API endpoint

Published Feb 11, 2026 · Updated Feb 11, 2026

Missing authentication in the ZLAN5143D v1.600 API allows remote attackers to change the device password over the network. The password-change endpoint performs the credential update without verifying an authenticated session or other authorization. Network reachability is the only disclosed gate; changing the credential can deny legitimate administrative access, while further post-change capabilities are undisclosed.
