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
Buffer overflow in ldcconn in Hewlett-Packard (HP) Controller for Cisco Local Director on HP-UX 11.11i allows remote attackers to execute arbitrary code via a long string to TCP port 17781.

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

Buffer overflow vulnerability in ldcconn component of HP Controller for Cisco Local Director running on HP-UX 11.11i allows remote attackers to execute arbitrary code by sending a specially crafted long string to TCP port 17781.

MitigationGiven HP-UX 11.11i is likely end-of-life, primary mitigation should involve network isolation via firewall/ACLs blocking external access to port 17781, or decommissioning the legacy system if replacement is feasible.

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. Identify the HP-UX version
    Run 'uname -a' or 'swlist -l bundle' to confirm the operating system version is HP-UX 11.11i
    Affected if The system is running HP-UX 11.11i specifically
  2. Check if HP Controller for Cisco Local Director is installed
    Run 'swlist' or 'swlist -l product' to list installed HP products and look for 'HP Controller for Cisco Local Director' or similar
    Affected if This product is installed on the system
  3. Verify the ldcconn component is present
    Check for the ldcconn executable or service process using 'ps -ef | grep ldcconn' or searching in typical HP product directories
    Affected if The ldcconn component is found running or installed
  4. Confirm TCP port 17781 is listening
    Run 'netstat -an | grep 17781' or 'nmap -p 17781 localhost' to check if port 17781 is open and accepting connections
    Affected if Port 17781 is open and listening on any interface

A system is affected if it runs HP-UX 11.11i with HP Controller for Cisco Local Director installed, has the ldcconn component active, and has port 17781 exposed.
