CVE-2021-21908

Specially-crafted command line arguments can lead to arbitrary file deletion.

MEDIUM 6.5EPSS 1.44%

Does this matter?

Lower severity and a low EPSS score (1.44%). Track it; it rarely justifies an emergency change on its own.

Description

Specially-crafted command line arguments can lead to arbitrary file deletion. The handle_delete function does not attempt to sanitize or otherwise validate the contents of the [file] parameter (passed to the function as argv[1]), allowing an authenticated attacker to supply directory traversal primitives and delete semi-arbitrary files.
