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
CSPOC in IBM PowerHA SystemMirror on AIX 6.1 and 7.1 allows remote authenticated users to perform an "su root" action by leveraging presence on the cluster-wide password-change list.

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 confidence

CSPOC (Cluster Services Point of Control) in IBM PowerHA SystemMirror on AIX 6.1 and 7.1 contains a privilege escalation vulnerability where remote authenticated users can execute 'su root' by exploiting their presence on the cluster-wide password-change list, effectively bypassing normal authorization controls to gain root access.

MitigationApply IBM APARs/patches for PowerHA SystemMirror to address this privilege escalation, and review/clean the cluster-wide password-change list to remove unauthorized entries.

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 PowerHA SystemMirror is installed
    Run 'lslpp -l | grep -i powerha' or 'lscluster -ver' on the AIX system to list installed PowerHA packages and version
    Affected if PowerHA SystemMirror packages are found on AIX 6.1 or 7.1 systems
  2. Verify CSPOC component is configured
    Check if CSPOC is enabled in the cluster configuration using 'lscluster -c' or review clusternode settings via 'lscluster -ni'
    Affected if CSPOC/Cluster Services Point of Control is active or configured in the PowerHA cluster
  3. Inspect the cluster-wide password-change list
    Locate and review the cluster-wide password-change list file (typically in /var/ha/cluster or configuration directory) for unauthorized or unexpected user entries
    Affected if Unauthorized or unexpected user accounts are present in the cluster password-change list
  4. Check user cluster permissions
    Review which authenticated users have cluster access permissions via 'lsuser -a' or cluster management tools, focusing on users with elevated privileges
    Affected if Remote authenticated users exist who have been added to the cluster-wide password-change mechanism allowing 'su root' access

A system is affected if it runs PowerHA SystemMirror on AIX 6.1 or 7.1 with CSPOC configured and contains unauthorized entries in the cluster-wide password-change list that allow privilege escalation to root.
