Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Pre- and post-publication reviews prevent insertion of sensitive information into externally-accessible public locations.
Monitors for sensitive information placed in externally accessible files or directories.
The map shows if data actions result in sensitive information being placed in externally accessible locations.
Isolation and eradication reduce the ability to exploit sensitive information inserted into externally-accessible files or directories.
Approved categorization forces identification of externally accessible files that contain sensitive content so they receive proper protection.
The pre-implementation review identifies externally accessible files or directories containing PII and drives access restrictions or removal.
Tainting makes it possible to determine when sensitive data has been removed from externally accessible files or directories.
OPSEC practices stop placement of supply-chain information into locations accessible to external parties.
Mitigating Controls (NIST CSF 2.0) AI
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.
Least-privilege file and directory permissions directly prevent unauthorized actors from reading sensitive data placed in accessible locations.
Protecting data-at-rest encompasses file-level access controls and encryption that stop exposure of sensitive information in externally reachable paths.
Hardened configuration baselines and ongoing config management reduce the chance that sensitive data is written to world-readable files or directories.
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.
By ensuring that only the minimum necessary data is present in files or directories that may be reachable by external parties, the control lowers the impact of any subsequent exposure.
Requiring visible or metadata labels on classified information helps ensure that files placed in externally accessible locations still carry an explicit sensitivity marker, lowering the likelihood of unnoticed exposure.
The control’s requirement to remove or securely destroy information stored in externally accessible locations reduces the risk of sensitive data being left in files or directories that external parties can reach.
Logging disposals, selecting vetted external disposal services, and protecting media according to classification reduce the likelihood that sensitive information ends up in externally accessible files or directories.
Verifying and sanitizing equipment prior to disposal or resale prevents sensitive files or directories from remaining accessible to external parties who later obtain the hardware.
