CVE-2023-43202

Authenticated command execution via packet-capture filename injection

Published Sep 20, 2023 · Updated Sep 24, 2024

Command injection in D-Link DWL-6610AP firmware 4.3.0.8B003C allows remote authenticated users to execute arbitrary commands. The pcap_download_handler function incorporates the update.device.packet-capture.tftp-file-name value into a command without neutralizing shell syntax. Access to the packet-capture management function from an adjacent network is required, and injected commands can read, alter, or interrupt the appliance.
