Vulnerability Data
The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This…
more
flaw breaks backups and migrations, causing files moved by a privileged user (e.g., root) to become root-owned unexpectedly, which can lead to information disclosure or restricted access for the intended owners.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires preservation of security attributes (owner UID/GID) on objects during operations such as cross-filesystem moves.
Mandates timely remediation of flaws in system utilities that fail to preserve file ownership metadata.
Limits the ability of privileged accounts to perform moves that would incorrectly reassign ownership to the caller's UID/GID.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege permission policies and reviews directly prevents incorrect permission propagation on copy/restore/share operations.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Access-control policy defines how permissions must be preserved when objects are copied or shared.
Access-rights provisioning and review processes directly address the risk of overly permissive copied objects.
Privileged-access management includes rules for maintaining correct permissions on copied or restored data.
Information-access-restriction controls enforce least-privilege permissions that must be preserved during copy/restore operations.
Change-management procedures can require verification that permissions remain intact after modifications or restores.
Configuration baselines can embed permission settings, indirectly reducing the chance of incorrect preservation.
