FKIE_CVE-2021-21908

Vulnerability from fkie_nvd - Published: 2021-12-22 19:15 - Updated: 2026-06-17 03:36
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H
Summary
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.
