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 · unedited
A Remote Disclosure of Information vulnerability in HPE NonStop Servers using SSH Service version L series: T0801L02 through T0801L02^ABX; J and H series: T0801H01 through T0801H01^ACA was found.

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 confidence

A Remote Disclosure of Information vulnerability exists in HPE NonStop Servers running SSH Service. The vulnerability affects specific version ranges of the SSH service on L series (T0801L02 through T0801L02^ABX) and J/H series (T0801H01 through T0801H01^ACA) NonStop systems, potentially allowing unauthorized disclosure of sensitive system information via the SSH protocol.

MitigationApply the appropriate HPE patch to update the SSH Service to a fixed version beyond the affected ranges. If patches are unavailable, restrict SSH access via network controls and monitor for unauthorized information disclosure attempts.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm HPE NonStop system
    Run 'uname -a' or 'nodeinfo' command in the OSS shell to verify the operating system is HPE NonStop
    Affected if System is not HPE NonStop - not applicable
  2. Check NonStop OSS version
    Run the 'version' command or inspect /etc/hpws_version to obtain the OSS version number
    Affected if Version is within t0801h01 through t0801h01^aca (H/J series) OR t0801l02 through t0801l02^abx (L series)
  3. Verify SSH service is enabled
    Run 'ps -ef | grep ssh' or check Pathway process list to confirm the SSH daemon (sshd) is running
    Affected if SSH service is not present or not running - vulnerability cannot be triggered
  4. Confirm SSH service version
    Run 'ssh -V' or check the SSH daemon binary version to identify the SSH implementation version
    Affected if SSH version corresponds to the affected NonStop OSS version ranges listed above

A system is affected if it is an HPE NonStop server with OSS version in the ranges t0801h01 to t0801h01^aca or t0801l02 to t0801l02^abx, and the SSH service is enabled and running.

Mitigation

Apply the appropriate HPE patch to update the SSH Service to a fixed version beyond the affected ranges. If patches are unavailable, restrict SSH access via network controls and monitor for unauthorized information disclosure attempts.
