CVE-2020-1052: 
vulnerability analysis and mitigation

CVE-2020-1052 is an elevation of privilege vulnerability that exists in the way that the ssdpsrv.dll handles objects in memory. The vulnerability was discovered and reported to Microsoft in 2019, with the CVE being assigned on November 4, 2019. This vulnerability affects multiple versions of Microsoft Windows operating systems, including Windows 10, Windows 7 SP1, Windows 8.1, Windows Server 2008, 2012, 2016, and 2019 (NVD).

The vulnerability exists due to improper handling of objects in memory by the ssdpsrv.dll component. 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 requirements with low attack complexity and privilege requirements (NVD).

When successfully exploited, this vulnerability allows an attacker to execute code with elevated permissions, potentially gaining higher privileges on the affected system. The impact is significant as it could allow a locally authenticated attacker to escalate their privileges on the targeted system (CVE).

To exploit this vulnerability, a locally authenticated attacker would need to run a specially crafted application. The attack requires local access to the target system, making it less severe than remotely exploitable vulnerabilities (NVD).

Microsoft has addressed this vulnerability by releasing security updates that ensure ssdpsrv.dll properly handles objects in memory. The fix is available through various KB updates for affected Windows versions (Rapid7).
