How to fix?

Upgrade Echo:latest busybox to version 1:1.27.2-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.
