CVE-2020-1546: 
vulnerability analysis and mitigation

CVE-2020-1546 is an elevation of privilege vulnerability that exists when the Windows Backup Engine improperly handles memory. The vulnerability was discovered and disclosed to Microsoft, who assigned it a unique identifier among several related Windows Backup Engine vulnerabilities (MITRE).

The vulnerability stems from improper memory handling in the Windows Backup Engine component. This security issue is part of a group of similar vulnerabilities (CVE-2020-1535, CVE-2020-1536, CVE-2020-1539, CVE-2020-1540, CVE-2020-1542, CVE-2020-1543, CVE-2020-1544, CVE-2020-1545, CVE-2020-1547, CVE-2020-1551) that affect the same component (MITRE).

If successfully exploited, this vulnerability allows an attacker to elevate their privileges on the affected system. However, the attacker must first gain execution capabilities on the target system before they can exploit this vulnerability (MITRE).

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

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 (MITRE).
