Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces access restrictions on the iDRAC remote interface so that even high-privileged accounts cannot retrieve sensitive BIOS/firmware data beyond their authorized scope.

AC-17 Remote Access good match
prevent

Requires explicit authorization, encryption, and usage restrictions for all remote management connections to iDRAC, blocking the attack vector described in the CVE.

AC-6 Least Privilege partial match
prevent

Limits the set of privileges granted to remote administrators, reducing the amount of sensitive information that can be disclosed if the vulnerability is triggered.

ID.RA-09 partial match
prevents

Pre-acquisition hardware integrity assessment can identify devices with uncleared debug exposure before purchase.

PR.PS-03 partial match
prevents

Hardware replacement policy can retire devices whose debug interfaces fail to clear sensitive state.

A.8.29 Security testing in development and acceptance mostly match
detects

Security testing in development can detect uncleared debug information before release.

A.8.24 Use of cryptography partial match
degrades

Cryptographic key management and secure handling requirements reduce exposure of sensitive values during debug entry.

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

Secure system architecture and engineering principles directly address clearing of sensitive data on debug transitions.

A.8.28 Secure coding partial match
degrades

Secure coding practices can mandate explicit clearing of debug registers and memory.

A.8.33 Test information partial match
degrades

Test information protection includes ensuring debug artifacts do not leak sensitive data.
