Summary

CVE-2024-30406 is a medium-severity Cleartext Storage in a File or on Disk (CWE-313) vulnerability in Juniper Junos Os Evolved. Its CVSS base score is 6.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 3th 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 SC-28 (Protection of Information at Rest) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SC-28 Protection of Information at Rest good match

SC-28 requires cryptographic or equivalent protection of sensitive information at rest, directly eliminating cleartext file/disk storage.

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.

PR.DS-01 full match
prevents

Encryption of data-at-rest directly prevents cleartext storage while the control also addresses integrity and availability.

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.

A.8.24 Use of cryptography full match
prevents

Cryptography control directly mandates encryption of sensitive data at rest.

A.5.12 Classification of information partial match
prevents

Classification identifies sensitive data that must not be stored in cleartext.

A.5.14 Information transfer partial match
degrades

Transfer policies can require encryption, indirectly reducing cleartext storage risk.

A.8.10 Information deletion partial match
degrades

Deletion policies help remove sensitive cleartext files when no longer needed.

A.8.11 Data masking partial match
mitigates

Masking reduces exposure of sensitive values that might otherwise be stored in cleartext.

A.8.12 Data leakage prevention partial match
finds

DLP can detect and block attempts to write sensitive data in cleartext.
