Summary

A vulnerability in OpenWrt luci-app-samba4 allows authenticated delegated users to execute the Samba daemon with caller-controlled command-line arguments. Attackers can pass arbitrary Samba global options such as message command to a root smbd process, triggering command execution when SMB protocol messages are processed.

Risk Assessment

The organization is at risk of remote code execution with root privileges by an authenticated attacker, potentially leading to full compromise of the OpenWrt device.

Recommendation

Immediately update the luci-app-samba4 package to the latest version available in the OpenWrt repository and restrict access permissions to the /usr/sbin/smbd file.
