Subsequent system confidentiality: None
Subsequent system integrity: None

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

Attack Vector: Local: The vulnerable system 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 through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Detectable: no evidence on record.

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 2026-10-25.

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.

What to do

AI-suggested

1. Apply firmware updates from Intel as soon as they become available to address the improper initialization flaw in CSME. 2. Restrict and monitor privileged local access to systems, ensuring that only trusted administrators have elevated rights. 3. Employ endpoint detection and response (EDR) solutions to detect suspicious local activities that might indicate exploitation attempts. 4. Implement strict access controls and auditing on systems with Intel CSME to quickly identify unauthorized privilege escalations. 5. Use hardware-based security features and platform integrity checks to reduce the risk of firmware tampering. 6. Maintain a robust patch management process to ensure timely deployment of security updates. 7. Educate system administrators about the risks of local privilege misuse and encourage the use of least privilege principles. 8. For highly sensitive environments, consider additional isolation or segmentation of systems with vulnerable firmware until patches are applied.

Description

Improper initialization in firmware for some Intel(R) CSME may allow a privileged user to potentially enable information disclosure via local access.

Impact

For European organizations, the primary impact of CVE-2023-48361 is the potential unauthorized disclosure of sensitive information from systems running vulnerable Intel CSME firmware. This could include cryptographic keys, platform configuration data, or other security-sensitive information managed by CSME. While exploitation requires local privileged access, the vulnerability could be leveraged in scenarios where attackers have already compromised user or administrator accounts, thereby escalating their capabilities. This poses a risk particularly to sectors with high security requirements such as government, finance, critical infrastructure, and telecommunications. The confidentiality breach could facilitate further lateral movement or privilege escalation within networks. However, since the vulnerability does not affect system integrity or availability, the immediate operational disruption risk is low. The medium severity rating suggests that while the threat is not critical, it should not be ignored, especially in environments where Intel hardware is prevalent and sensitive data is processed.
