CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:NSummary
CVE-2025-52642 is a low-severity Insertion of Sensitive Information into Externally-Accessible File or Directory (CWE-538) vulnerability in Hcltech Aion. Its CVSS base score is 3.3 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-16 (Security and Privacy Attributes) — see the control section below for these in your framework.

Vulnerability Data
HCL AION is affected by a vulnerability where internal filesystem paths may be exposed through application responses or system behaviour. Exposure of internal paths may reveal environment structure details which could potentially aid in further targeted attacks or information disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Enforces per-object authorizations so that even if a file or directory is reachable, the sensitive contents remain inaccessible to unauthorized actors.
Associates sensitivity labels with data objects so that subsequent storage or flow decisions can enforce that only appropriately protected files or directories receive the data.
Controls information flows between objects, directly stopping sensitive data from being written into locations whose ACLs or visibility would expose it.
Requires confidentiality protection of information at rest, which can be implemented by restricting storage locations or encrypting contents that would otherwise be placed in externally visible files.
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.
