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 nnmRptConfig.exe in HP OpenView Network Node Manager (OV NNM) 7.51 and 7.53 allows remote attackers to execute arbitrary code via a long data_select1 parameter.

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 in nnmRptConfig.exe in HP OpenView Network Node Manager allows remote attackers to execute arbitrary code via a long data_select1 parameter. This is a critical (CVSS 10) remote code execution vulnerability affecting versions 7.51 and 7.53.

MitigationApply vendor patches if available; otherwise, restrict network access to the affected service and consider disabling nnmRptConfig.exe until patching is possible.

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. Locate the nnmRptConfig.exe binary
    Search for nnmRptConfig.exe in the HP OpenView Network Node Manager installation directory, typically under OV/bin or OV/www/cgi-bin
    Affected if The executable exists and the product version is 7.51 or 7.53
  2. Confirm the installed NNM version
    Check the product version through the Windows Add/Remove Programs panel, the application's About dialog, or the version information of the nnmRptConfig.exe file itself
    Affected if Version is listed as 7.51 or 7.53 specifically
  3. Determine if the CGI interface is network-accessible
    Review the web server configuration (Apache or IIS) to see if the nnmRptConfig.exe CGI script is exposed and reachable over HTTP/HTTPS from network sources
    Affected if The nnmRptConfig CGI endpoint is listening on a reachable network interface and the data_select1 parameter can be submitted remotely

You are affected if HP OpenView Network Node Manager version 7.51 or 7.53 is installed and the nnmRptConfig.exe CGI interface is accessible over the network.
