CVE-2023-48859Network attack vector

Authenticated code execution via incorrect authorization

Published Dec 6, 2023 · Updated Aug 2, 2024

Remote code execution in TOTOLINK A3002RU firmware 2.0.0-B20190902.1958 allows remote authenticated users to execute arbitrary code. The public record identifies incorrect authorization that bypasses front-end restrictions, but the affected endpoint and failed server-side check remain undisclosed. A valid authenticated session is required, and successful exploitation grants code execution affecting device confidentiality, integrity, and availability.
