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
AIX routed allows remote users to modify sensitive files.

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 · low confidence

The AIX routed daemon contains a vulnerability that allows remote users to modify sensitive files on the system. This appears to be a file permission or path traversal issue in the routing daemon that could enable unauthorized file system access.

MitigationDisable the routed daemon if not required, apply relevant AIX patches from IBM for this vulnerability, and implement network access controls to limit exposure to untrusted networks.

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. Check AIX version
    Run 'oslevel -r' or 'lsmid -c oslevel' to determine the installed AIX version
    Affected if AIX version is 3.2, 4.1, 4.2, or 4.3 (specifically any version in the 320, 410, 420, or 430 release family)
  2. Verify routed daemon is running
    Run 'ps -ef | grep routed' to check if the routed process is active on the system
    Affected if The routed daemon process is running (routed or gated process is visible)
  3. Check routed daemon start-up configuration
    Examine /etc/rc.net or run 'lssrc -s routed' to see if routed is configured to start at boot or is currently active
    Affected if The routed service is enabled in the system startup configuration or currently active as a subsystem

The system is affected if it runs AIX version 3.2, 4.1, 4.2, or 4.3 AND has the routed daemon enabled and running, as the file permission or path traversal flaw in the routing daemon would then be exploitable.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Disable the routed daemon if not required, apply relevant AIX patches from IBM for this vulnerability, and implement network access controls to limit exposure to untrusted networks.
