Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should immediately upgrade all instances of tpm2-tools to version 5.7 or later, where the vulnerability has been patched. Since exploitation requires local access, organizations should also enforce strict access controls and monitoring on systems with TPM-enabled attestation, limiting user privileges and employing robust endpoint detection and response (EDR) solutions to detect suspicious local activities. Regularly auditing TPM quote verification processes and logs can help identify anomalies indicative of tampering attempts. For environments relying on remote attestation, implementing additional layers of verification beyond TPM quotes, such as behavioral analytics or hardware-based attestation extensions, can reduce reliance on a single point of failure. Security teams should also ensure that firmware and TPM microcode are up to date, as vulnerabilities in TPM hardware or firmware could compound risks. Finally, integrating vulnerability management processes to track and promptly apply updates to security-critical tools like tpm2-tools is essential to maintain platform trustworthiness.

Description

tpm2-tools is the source repository for the Trusted Platform Module (TPM2.0) tools. A malicious attacker can generate arbitrary quote data which is not detected by `tpm2 checkquote`. This issue was patched in version 5.7.

Impact

For European organizations, the impact of CVE-2024-29038 lies primarily in the potential undermining of TPM-based attestation processes. Many enterprises, government agencies, and critical infrastructure operators in Europe rely on TPM 2.0 for secure boot, measured boot, and remote attestation to ensure platform integrity and compliance with security policies. If an attacker can generate arbitrary quote data undetected, it could allow bypassing security controls that depend on TPM attestation, potentially enabling stealthy persistence or unauthorized changes to critical systems. Although exploitation requires local access, insider threats or attackers who have already gained limited footholds could leverage this vulnerability to evade detection. This risk is particularly relevant for sectors with stringent security requirements such as finance, healthcare, energy, and government. However, since the vulnerability does not allow privilege escalation or direct system compromise, the overall risk is moderate. The absence of known exploits reduces immediate threat levels but does not eliminate the need for remediation.

CWE-1283Mutable Attestation or Measurement Reporting Data (opens in a new tab)
Base weakness
The register contents used for attestation or measurement reporting data to verify boot flow are modifiable by an adversary.
Architecture and Design
Measurement data should be stored in registers that are read-only or otherwise have access controls that prevent modification by an untrusted agent.
