CVE-2022-23723Network attack vector

MFA bypass via adapter HTML template flow

Published May 2, 2022 · Updated Aug 3, 2024

Authentication bypass in Ping Identity PingOne MFA Integration Kit 1.4 through 1.5.2 allows remote authenticated users to bypass MFA. The flaw is reached when adapter HTML templates participate in an authentication flow, but Ping Identity has not published the erroneous template operation or request handling. A valid first-factor session and a template-based adapter flow are required; the reported consequence is MFA evasion, not code execution or service interruption.
