CVE-2020-1081: 
vulnerability analysis and mitigation

CVE-2020-1081 is an elevation of privilege vulnerability that exists when the Windows Printer Service improperly validates file paths while loading printer drivers. The vulnerability was disclosed on May 21, 2020, affecting multiple versions of Microsoft Windows operating systems including Windows 10, Windows 8.1, and Windows 7 SP1 (NVD).

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: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 Windows Printer Service component (NVD).

If successfully exploited, this vulnerability could allow an attacker to gain elevated privileges on the affected system. The high CVSS scores for confidentiality, integrity, and availability (C:H/I:H/A:H) indicate that successful exploitation could result in complete compromise of the system's security (NVD).

The vulnerability requires local access and low privileges to exploit, suggesting that an attacker would need prior access to the target system. The attack complexity is rated as low, indicating that the vulnerability is relatively straightforward to exploit once the necessary access is obtained (NVD).

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