CVE-2021-41992
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 · uneditedA misconfiguration of RSA in PingID Windows Login prior to 2.7 is vulnerable to pre-computed dictionary attacks, leading to an offline MFA bypass.
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 confidencePingID Windows Login prior to version 2.7 contains a misconfigured RSA implementation that is vulnerable to pre-computed dictionary attacks, allowing attackers to bypass MFA authentication offline.

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.
-
Verify PingID Windows Login is installedCheck for PingID Windows Login installation via Windows Programs and Features, or look for PingID-related services/processes running on the systemAffected if PingID Windows Login is present on the system
-
Determine installed PingID versionOpen Windows Programs and Features, locate PingID Integration for Windows Login, and note the version column; or right-click the PingID application executable and view Properties > Details for version informationAffected if Version is displayed as lower than 2.7
-
Compare version to affected rangeIf version is visible in Programs and Features or file properties, compare it against the affected range: any version less than 2.7 is vulnerableAffected if Installed version is < 2.7 (for example, 2.6, 2.5, 2.4, etc.)
-
Locate PingID configuration filesSearch the system for PingID configuration directories (commonly in Program Files or ProgramData folders) and locate RSA or cryptographic configuration files associated with the PingID Windows Login componentAffected if Vulnerable RSA configuration is present and the version is below 2.7
If PingID Windows Login is installed and its version is lower than 2.7, the environment is affected by this vulnerability.
