CVE-2025-32456Public exploitNetwork attack vector

Root command execution via unsanitized tftp arguments

Published Jun 8, 2025 · Updated Jun 10, 2025

Argument injection in onsemi Quantenna Wi-Fi chipsets using SDK 8.0.0.28 and earlier allows remote attackers to execute commands as root. The router_command.sh put_file_to_qtn branch expands its second, third, and fourth arguments directly into a tftp command without sanitizing injected delimiters. Remote unauthenticated exploitation requires an end product that leaves qcsapi RPC enabled; successful execution permits full chipset control.
