AI Analysis
Technical Summary
On ARM platforms, a design flaw in the HDD Password architecture within InsydeH2O firmware allows an attacker to retrieve HDD Password credentials from UEFI variables. This vulnerability is classified as CWE-522 (Insufficiently Protected Credentials) and affects Insyde Software's InsydeH2O and InsydeH2O ARM products. The CVSS 3.1 base score is 6.9, reflecting a medium severity with high impact on confidentiality, integrity, and availability, but requiring physical access or local privileges with user interaction and high attack complexity.
Potential Impact
An attacker with local low privileges and user interaction on an ARM platform running vulnerable InsydeH2O firmware could retrieve HDD Password credentials stored insecurely in UEFI variables. This compromises confidentiality and potentially integrity and availability of the system's HDD password protection mechanism. No known exploits are reported, so active exploitation is not confirmed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit local access to trusted users and monitor for suspicious activity. No official fix or workaround has been provided in the available data.
