vulnerability analysis and mitigation

An elevation of privilege vulnerability exists in the way the Provisioning Runtime validates certain file operations, known as 'Provisioning Runtime Elevation of Privilege Vulnerability'. This vulnerability was assigned CVE-2020-0808 and was disclosed in March 2020. The vulnerability affects various versions of Microsoft Windows operating systems (NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) with the following vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This indicates that the vulnerability requires local access, low attack complexity, low privileges, and no user interaction to exploit. The vulnerability is related to improper input validation (CWE-20) in the Provisioning Runtime component (NVD).

If successfully exploited, this vulnerability could allow an attacker to gain elevated privileges on the affected system. The attacker could potentially gain the same user rights as the local user, with those having administrative rights being more severely impacted than users with fewer privileges (NVD).

Microsoft has released security updates to address this vulnerability. Users should apply the appropriate patches through Windows Update to protect their systems (MSRC).
