Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

dbcve analysis · high confidence

The AWS VPN Client for macOS versions 1.3.2-5.2.0 has a symlink vulnerability in its log rotation mechanism. The client insufficiently validates the log destination directory, allowing a non-administrator user to create a symlink from a client log file to a privileged location. By injecting arbitrary code through crafted API calls into the log file, the user can achieve code execution with root privileges when log rotation occurs.

MitigationUpgrade AWS VPN Client for macOS to version 5.2.1 or later to obtain the patch for this vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed AWS VPN Client version
    Run: ls /Applications/ | grep -i 'AWS VPN' to locate the app, then use: mdls -name kCFBundleShortVersionString '/Applications/AWS VPN Client.app' to retrieve the version number
    Affected if The version falls within 1.3.2 through 5.2.0 (inclusive)
  2. Confirm the application is actively used or installed
    Verify the app bundle exists at /Applications/AWS VPN Client.app and check its last modified date or recent usage
    Affected if The vulnerable application version is installed and present on the system
  3. Locate AWS VPN Client log directories
    Check common log locations: ls -la ~/Library/Logs/ | grep -i aws, and ls -la /var/log/ 2>/dev/null | grep -i aws for system-wide logs
    Affected if Log directories exist and are writable by non-administrator users
  4. Detect suspicious symlinks in log paths
    Use: find ~/Library/Logs -type l -ls 2>/dev/null to list all symlinks under user log directories, then examine their targets using: readlink on each symlink found
    Affected if Any symlink points to privileged locations outside the expected log directory (e.g., /Library/LaunchDaemons, /usr/local/bin, or other system directories)
  5. Inspect log rotation configuration
    Check for log rotation scripts or configuration files: ls -la /Library/Application\ Support/AWSVPNClient/ 2>/dev/null and examine any cron jobs or launch agents related to the VPN client
    Affected if Log rotation is automated via cron, launchd, or built-in mechanism that runs with elevated privileges

A system is affected if AWS VPN Client for macOS version 1.3.2 through 5.2.0 is installed and log directories or rotation mechanisms are accessible to non-administrator users who could create malicious symlinks.
