Summary

CVE-2024-29038 is a medium-severity Mutable Attestation or Measurement Reporting Data (CWE-1283) vulnerability in Tpm2-Tools Project Tpm2-Tools. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 30th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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

IA-12 Identity Proofing good match

Requires identity proofing at appropriate assurance levels before granting accounts, directly addressing insufficient proof of identity.

IA-2 Identification and Authentication (Organizational Users) good match

Requires unique identification and authentication of users, directly stopping weak mechanisms from being used.

IA-3 Device Identification and Authentication good match

Requires device identification and authentication before establishing connections.

IA-8 Identification and Authentication (Non-organizational Users) good match

Extends strong identification and authentication requirements to non-organizational users.

AC-3 Access Enforcement good match

Access enforcement directly stops unauthorized writes to attestation registers by applying authorization checks before any modification.

AC-6 Least Privilege good match

Least privilege restricts which subjects or processes may alter measurement registers, reducing the attack surface for mutable attestation data.

PR.AA-03 full match
prevents

Explicitly requires authentication of users/services/hardware with MFA and password-strength controls.

ID.RA-09 mostly match
prevents

Directly requires assessing hardware/software integrity before use, which mitigates mutable attestation data.

PR.AA-02 mostly match
prevents

Identity proofing and binding is a core prerequisite for non-weak authentication.

PR.DS-01 mostly match
degrades

Protects integrity of data-at-rest, covering attestation registers and measurement values.

PR.AA-01 partial match
prevents

Credential management directly supports stronger authentication but does not guarantee proof of identity.

PR.PS-01 partial match
prevents

Enforces hardened configuration baselines that can include secure boot and attestation protections.

A.8.5 Secure authentication full match
prevents

Mandating multi-factor and non-password authentication techniques counters the use of inherently weak single-factor or password-only authentication mechanisms.

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

Security testing can detect weaknesses that permit mutable attestation data.

A.5.17 Authentication information partial match
prevents

Strong-password and non-reuse requirements raise the bar against weak single-factor authentication that can be exploited via guessing or credential stuffing.

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

Secure architecture principles require hardware-protected, immutable attestation registers.

A.8.9 Configuration management partial match
degrades

Configuration management enforces integrity of boot-time registers and measurement data.

A.8.24 Use of cryptography none match
none

Cryptographic integrity mechanisms can protect attestation data from unauthorized modification.
