Summary

CVE-2023-52433 is a high-severity Improper Check for Dropped Privileges (CWE-273) vulnerability in Netapp Ontap Tools. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 15th 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-6 (Least Privilege) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege partial match

Employing least privilege requires that privilege-dropping operations succeed and are verified before continuing.

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.AA-05 partial match
blocks

Least-privilege policy and enforcement directly motivate privilege-dropping code, yet the control does not address implementation-level verification of the drop.

PR.PS-06 partial match
blocks

Secure SDLC activities (code review, static analysis, testing) catch missing or incorrect privilege-drop checks, but eliminating only this one flaw covers only a fraction of the control's broader intent.

A.5.15 Access control partial match
removes

A.5.15 only requires defining policies, determining requirements, and referencing other controls for implementing access rules; it never mandates or performs the specific check for successful privilege drop that would remove CWE-273 from first-party code.

A.5.18 Access rights partial match
removes

A.5.18 governs the provisioning, review, and revocation of access rights granted to identities; it does not remove or mandate the removal of a first-party code defect in which a privilege drop is attempted but never verified.

A.8.18 Use of privileged utility programs partial match
degrades

Control of privileged utility programs includes ensuring privilege-dropping operations are verified before use.

A.8.19 Installation of software on operational systems partial match
removes
A.8.2 Privileged access rights partial match
removes

A.8.2 controls the allocation, review, expiry and use of privileged rights via authorization and policy; it does not remove the code-level defect in which a drop-privileges call is performed without checking its success

A.8.26 Application security requirements partial match
removes
