CVE-2023-5143Network attack vector

Authenticated privilege escalation via unvalidated table_name processing

Published Sep 24, 2023 · Updated Mar 6, 2025

Improper input validation in D-Link DAR-7000 20151231 allows remote authenticated users to escalate privileges via a crafted table_name. The /log/webmailattach.php handler processes the table_name parameter without adequate validation, but the exact unsafe operation is undisclosed. Low-privileged access to the network interface is required; public records do not establish whether escalation reaches code execution or full administration.
