CVE-2024-22245Public exploitNetwork attack vector

Authentication relay via arbitrary WebSocket ticket requests

Published Feb 20, 2024 · Updated Aug 27, 2024

Authentication relay in VMware Enhanced Authentication Plug-in all versions allows remote attackers to obtain arbitrary Kerberos service tickets. A malicious website connects to EAP's local WebSocket API and directs its helper process to request a ticket for any attacker-chosen SPN. A domain user must visit the site and accept EAP's communication prompt; the returned AP-REQ authenticates as that user to Kerberos-enabled services.
