CVE-2024-29640Public exploitNetwork attack vector

Authenticated command execution via unsanitized QR session ID

Published Mar 29, 2024 · Updated Jul 9, 2026

OS command injection in Messense aliyundrive-webdav 2.3.3 and earlier allows remote authenticated users to execute arbitrary commands. The OpenWrt LuCI action_query_qrcode handler appends the unvalidated sid form value to an aliyundrive-webdav qr query shell command executed by luci.sys.exec. Access requires a LuCI session authorized for the plugin; injected commands run with the web interface process's privileges and can read, alter, or interrupt the router.
