CVE-2024-50995Public exploit

Service crash via oversized SMB share name

Published Nov 5, 2024 · Updated Nov 5, 2024

Stack overflow in usb_remote_smb_conf.cgi in NETGEAR R8500 Firmware 1.0.2.160 allows remote authenticated users to crash the router. The CGI handler copies a crafted share_name value into a fixed-size stack buffer without checking the input length. Exploitation requires authenticated access from an adjacent network, and the documented consequence is an availability-only router crash.
