CVE-2020-1401: 
vulnerability analysis and mitigation

A remote code execution vulnerability (CVE-2020-1401) was identified in the Windows Jet Database Engine, discovered in 2019 and publicly disclosed in July 2020. The vulnerability occurs when the Windows Jet Database Engine improperly handles objects in memory. This vulnerability is distinct from related issues CVE-2020-1400 and CVE-2020-1407, affecting various versions of Microsoft Windows operating systems (NVD, CVE).

The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (High), with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. Under CVSS v2.0, it received a base score of 9.3 (High) with the vector (AV:N/AC:M/Au:N/C:C/I:C/A:C). The scoring indicates that while local access is required, no privileges are needed, though user interaction is necessary for exploitation (NVD).

If successfully exploited, this vulnerability could allow an attacker to execute remote code on the affected system, potentially gaining the same user rights as the current user. The high CVSS scores indicate severe potential impacts on the confidentiality, integrity, and availability of the affected systems (NVD).

The vulnerability requires user interaction for successful exploitation, as indicated by the CVSS vector string. The local access requirement suggests that an attacker would need to convince a user to open a specially crafted file or interact with malicious content to trigger the vulnerability (NVD).

Microsoft has released security updates to address this vulnerability. Users are advised to apply the appropriate patches through Windows Update or Microsoft's security guidance (Microsoft Advisory).
