CVE-2023-34800Public exploitNetwork attack vector

Unauthenticated OS command execution via service parameter

Published Jun 15, 2023 · Updated Dec 16, 2024

Command injection in D-Link Go-RT-AC750 revA_v101b03 allows remote attackers to execute arbitrary OS commands via a UPnP request. The genacgi_main handler places the unvalidated service query parameter from a SUBSCRIBE request into a shell command context. Unauthenticated network access to TCP port 49152 is sufficient, and the published proof of concept starts a Telnet daemon on the router.
