CVE-2020-1559: 
vulnerability analysis and mitigation

An elevation of privilege vulnerability exists in Windows Storage Services when it improperly handles file operations (CVE-2020-1559). The vulnerability was discovered and assigned in November 2019, affecting multiple versions of Microsoft Windows operating systems. This security issue has been assigned a CVSS v3.1 base score of 7.8 (HIGH) (NVD).

The vulnerability stems from improper file operation handling in Windows Storage Services. The CVSS v3.1 vector string is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local access requirements with low attack complexity. The vulnerability has been classified under CWE-269, suggesting it relates to improper privilege management (NVD).

Successful exploitation of this vulnerability could allow an attacker to gain elevated privileges on the affected system. The high severity rating indicates potential significant impact on system confidentiality, integrity, and availability (NVD).

To exploit this vulnerability, an attacker would first need to achieve code execution on a target system. Once this prerequisite is met, the attacker could run a specially crafted application to elevate their privileges (MITRE CVE).

Microsoft has released a security update that addresses this vulnerability by ensuring Windows Storage Services properly handles file operations. Users should apply the appropriate security patches to affected systems (MSRC).
