CVE-2022-22047 is a Windows Client Server Run-time Subsystem (CSRSS) Elevation of Privilege Vulnerability that was discovered and disclosed in July 2022. This zero-day vulnerability affects multiple versions of Microsoft Windows operating systems and was actively exploited in the wild before being patched (Hacker News).

The vulnerability 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. It is classified under CWE-426 (Untrusted Search Path) and allows an attacker to gain SYSTEM permissions through the Windows Client Server Runtime Subsystem (NVD).

When successfully exploited, this vulnerability enables attackers to gain SYSTEM-level permissions, allowing them to disable local services such as Endpoint Detection and Security tools. With elevated access, attackers can deploy tools like Mimikatz to recover additional admin and domain level accounts, potentially leading to rapid threat propagation across the network (Hacker News).

Microsoft addressed this vulnerability in their July 2022 Patch Tuesday security updates. Organizations are strongly advised to apply the security updates provided by Microsoft to affected systems (Krebs on Security).
