CVE-2022-48222 : Vulnerability Insights and Analysis

A security vulnerability has been identified in Acuant AcuFill SDK that can allow a standard user to execute arbitrary SYSTEM code, resulting in elevation of privileges.

Understanding CVE-2022-48222

This section will cover what CVE-2022-48222 is, its impact, technical details, and mitigation strategies.

What is CVE-2022-48222?

CVE-2022-48222 is a security issue found in Acuant AcuFill SDK before version 10.22.02.03. During installation, certutil.exe is called by the Acuant installer to install certificates. However, this process is not hidden and runs with elevated privileges, allowing a standard user to escape the window and gain a full SYSTEM command prompt window.

The Impact of CVE-2022-48222

The vulnerability allows an attacker to execute arbitrary SYSTEM code, leading to complete compromise and elevation of privileges on the affected system.

Technical Details of CVE-2022-48222
