CVE-2021-37443Public exploitNetwork attack vector

Authenticated arbitrary file deletion via path traversal

Published Jul 25, 2021 · Updated Aug 4, 2024

Path traversal in NCH IVM Attendant v5.12 and earlier allows remote authenticated users to delete arbitrary files via the logdeleteselected check0 parameter. The deletion handler accepts attacker-controlled path traversal input instead of restricting paths to the intended log directory. An authenticated account with sufficient application permission is required, and the consequence is arbitrary file deletion with potential service or data loss.
