Description

Improper Link Resolution Before File Access in the AWS VPN Client for macOS versions 1.3.2- 5.2.0 allows a local user to execute code with elevated privileges. Insufficient validation checks on the log destination directory during log rotation could allow a non-administrator user to create a symlink from a client log file to a privileged location. On log rotation, this could lead to code execution with root privileges if the user made crafted API calls which injected arbitrary code into the log file. We recommend users upgrade to AWS VPN Client for macOS 5.2.1 or the latest version.

Attack-Flow Graph

Mitigation Strategies

Upgrade the AWS VPN Client for macOS to version 5.2.1 or the latest available version to address the improper link resolution vulnerability and prevent potential code execution with elevated privileges.

Executive Summary

This vulnerability is an improper link resolution issue in the AWS VPN Client for macOS versions 1.3.2 to 5.2.0. It allows a local user to execute code with elevated privileges by exploiting insufficient validation during log rotation. A non-administrator user can create a symbolic link from a client log file to a privileged location. When the log rotates, crafted API calls can inject arbitrary code into the log file, which then executes with root privileges.

Impact Analysis

This vulnerability can allow a local non-administrator user to execute arbitrary code with root privileges on a macOS system running the affected AWS VPN Client versions. This can lead to full system compromise, unauthorized access, and control over the affected machine.
