CVE-2021-39270
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Ping Identity RSA SecurID Integration Kit before 3.2, user impersonation can occur.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Ping Identity RSA SecurID Integration Kit before version 3.2 contains a user impersonation vulnerability allowing an attacker to impersonate valid users, likely through improper session handling or authentication bypass in the integration layer between Ping Identity and RSA SecurID.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed RSA SecurID Integration Kit versionLocate the Integration Kit installation directory and check the version file, manifest, or product metadata. Common locations include the Ping Identity deployment directory or the kit's own lib folder. Look for version.info, manifest.mf, or similar version-tracking files.Affected if The installed version is lower than 3.2 (for example, 3.0, 3.1, or any version number below 3.2).
-
Confirm RSA SecurID integration is activeCheck the Ping Identity configuration for enabled RSA SecurID authentication mechanisms. Review the PingFederate or PingAccess runtime configuration files for RSA SecurID adapter or token provider references.Affected if The RSA SecurID integration kit is deployed and actively handling authentication flows for any application or service.
-
Review authentication session handlingExamine logs for session-related events from the integration kit. Look for patterns where session tokens may be improperly validated or where user context switches occur without proper re-authentication.Affected if Session handling logs show unexpected user identity changes, duplicate session tokens, or authentication events lacking complete validation traces.
You are affected if the RSA SecurID Integration Kit version is below 3.2 AND the integration is actively deployed in your authentication pipeline.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.2
Upgrade the RSA SecurID Integration Kit to version 3.2 or later to obtain the patch for user impersonation; verify the upgrade in a non-production environment before deployment.
3.2
- Download RSA SecurID Integration Kit version 3.2 or later from the official Ping Identity download portal
- Back up the current RSA SecurID Integration Kit configuration and any custom files
- Install version 3.2 by following the standard Ping Identity kit installation documentation
- Restore the backed-up configuration to the new installation
- Verify the installation was successful and the kit is functioning correctly
- Test user authentication flows to confirm the user impersonation vulnerability is resolved
