CVE-2021-39270Network attack vector

Unauthenticated user impersonation

Published Aug 18, 2021 · Updated Aug 4, 2024

Origin validation error in Ping Identity RSA SecurID Integration Kit before 3.2 allows remote attackers to impersonate users. Ping Identity has not published the affected request, field, or validation operation that accepts an untrusted origin. The network path requires no prior privileges or user interaction, and successful exploitation compromises authentication integrity by causing PingFederate to issue a SAML assertion for the impersonated username.
