CVE-2023-23632
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 · uneditedBeyondTrust Privileged Remote Access (PRA) versions 22.2.x to 22.4.x are vulnerable to a local authentication bypass. Attackers can exploit a flawed secret verification process in the BYOT shell jump sessions, allowing unauthorized access to jump items by guessing only the first character of the secret.
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 · high confidenceBeyondTrust PRA versions 22.2.x to 22.4.x contain a local authentication bypass in BYOT shell jump sessions. The secret verification process has a critical flaw allowing unauthorized access by guessing only the first character of the secret, enabling attackers to gain unauthorized access to jump items.

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 BeyondTrust PRA installed versionCheck the installed version of BeyondTrust Privileged Remote Access via the web interface (typically found in Help > About or System > Diagnostics) or by querying the installed software on the serverAffected if The installed version is 22.2.1 through 22.3.2 (inclusive)
-
Confirm BYOT jump sessions are configuredNavigate to the PRA administrative interface and examine the Jump Items or BYOT configuration section to determine if any BYOT (Bring Your Own Terminal) jump sessions are definedAffected if Any BYOT jump items exist in the configuration
-
Review jump session access logsExamine the BeyondTrust PRA access and session logs for any jump item access attempts, particularly those with incomplete or single-character secret submissionsAffected if Logs show successful authentication with only partial secret input or multiple failed attempts followed by successful single-character submissions
-
Verify secret verification mechanismCheck the configuration settings for jump item secrets in the PRA admin panel - specifically examine how the secret validation is implemented for BYOT shell jump sessionsAffected if The system accepts authentication with only the first character of the secret
A user is affected if their BeyondTrust PRA version falls within 22.2.1 to 22.3.2 and they have any BYOT jump sessions enabled, as the flawed secret verification allows unauthorized access with only the first character of the secret.

dbcve · scoped22.3.3
Update BeyondTrust PRA to a version beyond 22.4.x or apply the vendor-provided patch. Review access logs for unauthorized jump item access and consider disabling BYOT jump sessions until patched.
BeyondTrust Privileged Remote Access 22.3.3 or later
- Verify current BeyondTrust Privileged Remote Access version in the admin console or via system information
- Schedule a maintenance window for the upgrade procedure
- Download BeyondTrust Privileged Remote Access version 22.3.3 or later from the official BeyondTrust support portal
- Backup the current configuration following BeyondTrust backup procedures
- Apply the upgrade following the official upgrade documentation
- Verify the upgrade was successful by checking the version number
- Test that BYOT shell jump sessions now require the full secret for authentication
