CVE-2021-42001Network attack vector

MFA bypass via encryption library misconfiguration

Published Apr 30, 2022 · Updated Aug 4, 2024

Cryptographic misconfiguration in PingID Desktop before 1.7.3 allows attackers to expose sensitive data and complete an MFA challenge via OTP. Ping Identity identifies misconfigured encryption libraries but has not disclosed the affected library, key-handling error, or exposure path. Exploitation requires network access and high privileges, and successful abuse permits OTP-based MFA completion; no broader consequence is publicly detailed.
