  • Monitor for POST requests to /SAAS/auth/login/embeddedauthbroker/callback with body parameters: protected_state, userstore, username, password, userstoreDisplay, horizonRelayState, stickyConnectorId, and action — this is the exploit callback endpoint.
  • Detect successful exploitation by watching for an HZN= cookie being set in HTTP 302 responses from the /SAAS/auth/login/embeddedauthbroker/callback endpoint.
  • The exploit flow begins with a GET to /vcac/ followed by a redirect GET to /vcac/?original_uri=<RootURL>%2Fvcac to extract the protected_state value from the response body before posting to the auth callback.
  • The exploit uses a fixed password value of 'horizon' in the POST body — this static credential string can be used as an additional detection signal in the request body.
  • Use the Shodan favicon hash -1250474341 or FOFA queries for app="vmware-Workspace-ONE-Access" to identify exposed instances for proactive asset discovery and monitoring.
  • ·vSphere and the connectors for Workspace ONE Access and VMware Identity Manager are NOT affected by this vulnerability.
  • ·Because VMware updates are cumulative, applying the VMSA-2022-0014 patches also remediates the earlier VMSA-2022-0011 flaws (CVE-2022-22954, CVE-2022-22960).
