CVE-2025-21100: Information Disclosure in Intel(R) Server D50DNP and M50FCP boards
Improper initialization in the UEFI firmware for the Intel(R) Server D50DNP and M50FCP boards may allow a privileged user to potentially enable information disclosure via local access.
AI Analysis
Technical Summary
CVE-2025-21100 is a medium-severity vulnerability affecting the UEFI firmware of Intel Server D50DNP and M50FCP boards. The root cause is improper initialization within the UEFI firmware, which may allow a privileged local user to enable information disclosure. Specifically, the flaw exists in the firmware layer responsible for initializing hardware and system components before the operating system boots. Because the vulnerability requires privileged local access, an attacker must already have high-level permissions on the affected system. The vulnerability does not require user interaction and does not affect confidentiality, integrity, or availability beyond the potential for information disclosure. The CVSS 4.0 vector (AV:L/AC:H/AT:P/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) indicates that the attack vector is local, the attack complexity is high, privileges required are high, and no user interaction is needed. The vulnerability impacts the confidentiality of information at a high scope, meaning sensitive data accessible via the firmware could be exposed. There are no known exploits in the wild at this time, and no patches or vendor advisories are currently linked. The affected products are specific Intel server boards, which are typically deployed in enterprise and data center environments. The vulnerability could be exploited by an insider threat or an attacker who has already gained privileged access, potentially to gather sensitive firmware or system information that could aid in further attacks or reconnaissance.
Potential Impact
For European organizations, especially those operating data centers or critical infrastructure with Intel Server D50DNP and M50FCP boards, this vulnerability poses a risk of sensitive information leakage at the firmware level. Although exploitation requires privileged local access, the potential exposure of firmware-level information could facilitate lateral movement, privilege escalation, or targeted attacks against the organization's infrastructure. This is particularly concerning for sectors with strict data protection requirements such as finance, healthcare, and government agencies. The impact is limited to confidentiality and does not directly affect system availability or integrity, but the indirect consequences of leaked information could be significant. Organizations relying on these Intel server boards for critical workloads may face increased risk of insider threats or advanced persistent threats leveraging this vulnerability to deepen their foothold.
Mitigation Recommendations
Organizations should prioritize the following mitigations: 1) Restrict and monitor privileged local access to systems using Intel Server D50DNP and M50FCP boards to minimize the risk of exploitation by insiders or compromised accounts. 2) Implement strict access controls and use hardware-based security features such as Intel Trusted Execution Technology (TXT) or Platform Trust Technology (PTT) to protect firmware integrity. 3) Regularly audit and monitor firmware configurations and logs for suspicious activity indicative of attempts to exploit firmware vulnerabilities. 4) Engage with Intel or authorized vendors to obtain firmware updates or patches as they become available, and apply them promptly. 5) Employ network segmentation to isolate critical servers and limit the ability of attackers to move laterally to systems with these vulnerable boards. 6) Conduct security awareness training focused on insider threat detection and privileged access management. These steps go beyond generic advice by focusing on controlling privileged access and monitoring firmware-level security, which are critical given the local and privileged nature of this vulnerability.
