Account impersonation via stolen SAML responses
Published Oct 31, 2023 · Updated Sep 12, 2024
Open redirect in the VMware Workspace ONE UEM console allows remote attackers to steal a victim's SAML response and impersonate that user. The vendor has not disclosed which console endpoint accepts an untrusted destination or how its redirect validation fails. Exploitation requires a victim to follow the crafted redirect during a SAML login flow; the captured response enables login as that victim.
