CVE-2023-31271

Vulnerability

An improper access control vulnerability exists in Intel(R) VROC (Virtual RAID on CPU) software prior to version 8.0.8.1001. The flaw resides in the software's access control mechanisms, allowing an authenticated user with local access to bypass intended restrictions. This affects all versions before the fixed release [1].

Exploitation

An attacker must have valid authentication credentials and local access to the system running the vulnerable Intel VROC software. No additional user interaction or special privileges are required beyond standard authenticated access. The attacker can then exploit the improper access control to gain elevated privileges [1].

Impact

Successful exploitation enables an authenticated user to escalate their privileges on the local system. This could lead to unauthorized access to sensitive data, modification of system configurations, or full compromise of the affected host. The impact is limited to local privilege escalation [1].

Mitigation

Intel has released version 8.0.8.1001 of the VROC software to address this vulnerability. Users should update to this version or later. No workarounds have been provided. The vulnerability is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog as of the publication date [1].
