What to do now

  1. Check whether you run VMware Workspace ONE Access (including its related identity/connector components) and whether the OAuth2 ACS/authentication endpoints are reachable from the network.
  2. Compare your installed version to the vendor’s fixed release guidance; at minimum, ensure the impacted vrealize automation component is updated to a fixed level.
  3. Upgrade to the fixed version(s) listed by VMware; for vrealize automation, apply the fix so it is “fixed in 9.0”.
  4. If you cannot patch immediately, restrict network access so only trusted internal systems can reach the Workspace ONE Access OAuth2 authentication endpoints (block public reachability and limit inbound to required sources).
