CVE-2021-21909Network attack vector

Authenticated arbitrary file deletion via path traversal

Published Dec 22, 2021 · Updated Aug 3, 2024

Path traversal in Garrett Metal Detectors iC Module CMA Version 5.0 allows remote authenticated users to delete arbitrary files via crafted CLI arguments. The authenticated TCP CLI concatenates attacker-controlled .log or .cnt names onto storage directories without sanitization, and truncation permits traversal to files outside those directories. Access requires successful CLI authentication; exploitation can remove system or application files and disrupt device operation, but no code execution is documented.
