Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
