The vulnerability is an improper validation of integrity check value in Zscaler Client Connector for MacOS. This allows an attacker to cause a denial of service of the Client Connector binary, effectively removing the client's security functionality. The issue stems from insufficient validation of integrity checks, likely allowing tampered binaries or invalid checksums to cause the software to fail or be disabled.

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. Confirm Zscaler Client Connector is installed
    Run: ls /Applications/ | grep -i zscaler. Also check ~/Library/Application Support/ for any Zscaler components.
    Affected if No Zscaler Client Connector application is found in the system.
  2. Locate the application bundle
    If found, identify the full path to the .app bundle, typically /Applications/Zscaler Client Connector.app or similar naming variant.
    Affected if The application bundle path cannot be determined.
  3. Extract the installed version number
    Run: mdls -name kCFBundleShortVersionString /Applications/Zscaler\ Client\ Connector.app (adjust path if different). Alternatively, inspect the Info.plist within the app bundle for CFBundleShortVersionString.
    Affected if The version number cannot be retrieved from the application bundle.
  4. Compare against vulnerable version range
    Compare the extracted version string to the affected range: versions prior to 3.4 are vulnerable (e.g., 3.3.x, 3.2.x, earlier). Version 3.4 and later are not affected.
    Affected if The installed version is less than 3.4 (e.g., 3.3.0, 3.2.5, etc.).

A user is affected if Zscaler Client Connector is installed on MacOS and the retrieved version number is lower than 3.4.
