Name of the Vulnerable Software and Affected Versions luci-app-samba4 (affected versions not specified)

Description An issue in the read Access Control List (ACL) grants file.exec permission on /usr/sbin/smbd. This allows authenticated delegated users to execute the Samba daemon with command-line arguments controlled by the caller. An attacker can provide arbitrary Samba global options, such as the message command, to a root smbd process, which leads to command execution during the processing of SMB protocol messages.
