CVE-2023-38946Public exploitNetwork attack vector

Unauthenticated management access via unvalidated admin cookie

Published Mar 6, 2024 · Updated Aug 26, 2024

Improper access control in Multilaser RE160 firmware 5.07.51_pt_MTL01 and 5.07.52_pt_MTL01 allows remote attackers to access router management. The web management interface treats a request carrying the bare admin: cookie as authorized without validating a credential or session token. Reachability requires local-network access or a victim-run application able to send HTTP requests to the router; successful requests can read password-bearing backups and alter DNS, remote-access, and routing settings.
