CVE-2021-41149Network attack vector

Arbitrary file overwrite via traversing target names

Published Oct 19, 2021 · Updated Aug 4, 2024

Path traversal in Amazon Web Services tough before 0.12.0 allows remote authenticated users to overwrite files via crafted target names. The cache_target path joins its output directory with a target-derived filename without first rejecting traversal constructs. An attacker must control target metadata in a repository consumed by the application; writes use the application's filesystem permissions and can corrupt or replace accessible files.
