Summary

CVE-2025-47761 is a high-severity Exposed IOCTL with Insufficient Access Control (CWE-782) vulnerability in Fortinet Forticlient. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); 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-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires enforcement of access authorizations on system resources, which structurally stops an IOCTL from being exposed without proper controls.

AC-6 Least Privilege good match

AC-6 requires least-privilege assignments that limit which users or processes can reach privileged IOCTL functionality.

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 full match
prevents

Directly enforces least-privilege access permissions on interfaces such as IOCTLs.

PR.IR-01 mostly match
prevents

Protects environments from unauthorized logical access, which includes improperly exposed IOCTL entry points.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing IOCTL authorization during development.

A.8.2 Privileged access rights partial match
prevents

Privileged access rights directly restrict who may invoke sensitive IOCTLs.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes design-time access-control requirements for device interfaces.

A.8.26 Application security requirements partial match
prevents

Application security requirements capture the need for proper IOCTL authorization.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles mandate least-privilege access to kernel interfaces.

A.8.28 Secure coding partial match
prevents

Secure coding practices prevent omission of access-control checks on IOCTL handlers.
