CVE-2020-1545: 
vulnerability analysis and mitigation

CVE-2020-1545 is an elevation of privilege vulnerability in the Windows Backup Engine that was discovered in 2019 and publicly disclosed in 2020. The vulnerability exists due to improper memory handling in the Windows Backup Engine component. This vulnerability affects multiple versions of Microsoft Windows operating systems (NVD).

The vulnerability stems from improper memory handling in the Windows Backup Engine. It 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, indicating local access required with low attack complexity (NVD).

If successfully exploited, this vulnerability allows an attacker to elevate their privileges on the affected system. The attacker could then run specially crafted applications with elevated privileges, potentially gaining greater access to system resources and sensitive data (CVE).

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

Microsoft has addressed this vulnerability by releasing a security update that corrects how the Windows Backup Engine handles memory. The fix is available through Microsoft's standard update channels (CVE).
