CVE-2020-1534: 
vulnerability analysis and mitigation

An elevation of privilege vulnerability (CVE-2020-1534) was identified in the Windows Backup Service due to improper handling of file operations. The vulnerability was disclosed and patched by Microsoft in August 2020. This vulnerability affects various versions of Microsoft Windows operating systems (NVD).

The vulnerability received 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. Microsoft's assessment also rated it as High severity with a slightly different vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating local access is required for exploitation (NVD).

If successfully exploited, this vulnerability could allow an attacker to elevate their privileges on the affected system, potentially gaining higher levels of access to system resources and sensitive data. The vulnerability affects the confidentiality, integrity, and availability of the system with high severity ratings across all three aspects (NVD).

To exploit this vulnerability, an attacker would first need to gain execution access on the target system. Once achieved, they could run a specially crafted application to elevate their privileges (CVE).

Microsoft addressed this vulnerability by releasing a security update that corrects how the Windows Backup Service handles file operations. Users are advised to apply the security update to mitigate this vulnerability (NVD).
