CVE-2023-48860Network attack vector

Authenticated code execution via front-end access-control bypass

Published Dec 7, 2023 · Updated Aug 2, 2024

Remote code execution in TOTOLINK N300RT 3.2.4-B20180730.0906 allows remote authenticated users to execute arbitrary code. The management front end applies incorrect access control, permitting authenticated requests to bypass its security restrictions before code execution. A valid administrative session and network reachability to the management interface are required; successful exploitation grants control of the router.
