CVE-2023-49944
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 · uneditedThe Challenge Response feature of BeyondTrust Privilege Management for Windows (PMfW) before 2023-07-14 allows local administrators to bypass this feature by decrypting the shared key, or by locating the decrypted shared key in process memory. The threat is mitigated by the Agent Protection feature.

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 the installed BeyondTrust PMfW versionLocate the installed BeyondTrust Privilege Management for Windows version on the system. This is typically visible in Add/Remove Programs, the BeyondTrust dashboard, or the application itself.Affected if The installed version date is before July 14, 2023 (builds dated < 2023-07-14)
-
Confirm the Challenge Response feature is configuredCheck whether the Challenge Response authentication feature is enabled in the BeyondTrust PMfW policy configuration. This is typically found in the PMfW management console or policy settings.Affected if The Challenge Response feature is actively enabled or configured in the environment
-
Verify local administrator access existsDetermine if the user context being assessed has local administrator privileges on the Windows system where PMfW is installed.Affected if The user has local administrator rights on the endpoint, enabling potential exploitation of the authentication bypass
An environment is affected if it runs BeyondTrust Privilege Management for Windows versions dated before July 14, 2023 AND has the Challenge Response feature enabled, with a local administrator able to attempt the key decryption or memory search.
