CVE-2024-48638

Authenticated command injection via SubnetMask parameter

Published Oct 17, 2024 · Updated Oct 17, 2024

OS command injection in D-Link DIR-882 1.30b06 and DIR-878 1.30b08 allows remote authenticated users to execute commands via POST requests. SetGuestZoneRouterSettings inserts the attacker-controlled SubnetMask value into an OS command without neutralizing command syntax. Access to the adjacent network and a low-privileged authenticated session are required; successful requests run arbitrary commands on the router.
