CVE-2025-22453

CVE-2025-22453 is a vulnerability in Intel's Server Firmware Update Utility (SysFwUpdt) versions prior to 16.0.12. The root cause is improper input validation within Ring 3 (user applications), which can be exploited by a system software adversary with a privileged user account. This high-complexity attack requires specific conditions but no user interaction or special internal knowledge of the target [1].

Exploitation

Attackers must already have a privileged user context on the local system and meet additional attack requirements. The vulnerability is exploitable only via local access, meaning the adversary must be able to execute code on the vulnerable machine. The attack complexity is rated high, suggesting that multiple conditions or specific timing may be necessary for successful exploitation [1].

Impact

Successful exploitation could allow an attacker to execute arbitrary code with elevated privileges, leading to complete compromise of the system's confidentiality, integrity, and availability. The CVSS v3.1 base score is 7.5 (High), with the vector indicating high impact to all three security properties of the vulnerable system [1].

Mitigation

Intel has addressed this vulnerability in version 16.0.12 of the Server Firmware Update Utility. Users and administrators should update to this version or later to remediate the issue. No workarounds are mentioned in the advisory, and there is no indication that the vulnerability is listed in CISA's Known Exploited Vulnerabilities (KEV) catalog [1].
