CVE-2025-20009

Root

Cause CVE-2025-20009 stems from improper input validation within the GenerationSetup module of the UEFI firmware used on Intel Server D50DNP and M50FCP boards. This flaw resides in the firmware's handling of user-supplied input, which fails to adequately sanitize or validate data before processing, leading to a potential information disclosure vulnerability [1].

Exploitation

An attacker must have local access to the affected server and possess privileged user credentials (e.g., administrator or equivalent). The vulnerability is triggered through the GenerationSetup interface, which is typically accessible only to users with elevated privileges. No network-based attack vector exists; exploitation requires direct physical or remote console access with sufficient permissions [1].

Impact

Successful exploitation could allow a privileged attacker to read sensitive information from the firmware's memory or configuration storage. This may include credentials, cryptographic keys, or other confidential data that could be used to further compromise the system or adjacent infrastructure. The CVSS v3 base score of 4.1 reflects the limited attack complexity and required privileges [1].

Mitigation

Intel has released firmware updates to address this vulnerability. Affected users should consult the Intel Security Advisory INTEL-SA-01269 for specific firmware versions and update instructions. No workarounds are documented; applying the latest firmware is the recommended remediation [1].
