Summary
CVE-2024-27275 is a high-severity Incorrect Privilege Assignment (CWE-266) vulnerability in Ibm I. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique External Remote Services (T1133); ranked at the 5th 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) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Vulnerability Data
IBM i 7.2, 7.3, 7.4, and 7.5 contains a local privilege escalation vulnerability caused by an insufficient authority requirement. A local user without administrator privilege can configure a physical file trigger to execute with the privileges of a user socially…

engineered to access the target file. The correction is to require administrator privilege to configure trigger support.

Mitigating Controls (NIST 800-53 r5) AI
Mandates unique identification and authentication of organizational users before access, directly stopping improper authentication.
Requires unique identification and authentication of devices before establishing connections, preventing unauthenticated device claims.
Mandates unique identification and authentication of non-organizational users, directly addressing the weakness for external actors.
Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.
Manages authenticators with verification and secure distribution, reducing opportunities for improper authentication.
Account management defines and authorizes the exact privileges granted to each account or role.
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.
Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.
PR.AA-03 directly enforces authentication mechanisms that eliminate most improper-authentication defects, yet CWE-287 spans additional vectors (missing checks, flawed protocols, session handling) that one control does not fully close.
PR.AA-04 directly enables verification of identity assertions (mostly preventing CWE-287 in that scope) yet leaves many other authentication failure modes unaddressed (only partial prevention overall).
PR.AA-01 supplies and governs credentials/tokens that authentication relies on, removing some weak-credential cases, yet leaves verification logic, missing checks, and protocol flaws untouched.
PR.AA-02 ensures valid enrollment and unique credential binding, which reduces some improper-auth risks at issuance time but leaves runtime claim verification untouched, so each direction only partially addresses the other.
PR.PS-01 can enforce auth-related settings via hardened baselines and default reviews, blocking some config-based instances of CWE-287, yet leaves code-level auth flaws untouched so neither direction reaches mostly.
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.
Requiring authentication methods whose strength matches the sensitivity of the data and mandating multi-factor authentication directly blocks attempts to access resources without proving identity.
Verifying user identity before issuing replacement credentials and forcing changes after compromise reduces the likelihood that authentication bypass can be achieved through stolen or weak credentials.
The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.
Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.
Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.
Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.
