CVE-2023-37243

CWE-379Published: October 31, 2023· Updated: Jun 17, 2026

7.8

CVSS v3.1

Official Description

The C:\Windows\Temp\Agent.Package.Availability\Agent.Package.Availability.exe file is automatically launched as SYSTEM when the system reboots. Since the C:\Windows\Temp\Agent.Package.Availability folder inherits permissions from C:\Windows\Temp and Agent.Package.Availability.exe is susceptible to DLL hijacking, standard users can write a malicious DLL to it and elevate their privileges.

Technical Analysis

CVE-2023-37243 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
