CVE-2022-20850

Arbitrary file deletion via CLI path injection

Published Sep 30, 2022 · Updated Nov 1, 2024

Path traversal in Cisco SD-WAN allows local users with authenticated CLI access to delete arbitrary files via crafted file paths. The CLI accepts attacker-supplied path information without sufficient validation and applies it to file-deletion operations outside the intended path. Successful exploitation requires local, low-privileged CLI access and permits deletion from the affected device file system, with no reported read or execution capability.
