CVE-2010-1551
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 · uneditedStack-based buffer overflow in the _OVParseLLA function in ov.dll in netmon.exe in Network Monitor in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to execute arbitrary code via the sel 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 confidenceStack-based buffer overflow in the _OVParseLLA function in ov.dll within netmon.exe in HP OpenView Network Node Manager versions 7.01, 7.51, and 7.53 allows remote attackers to execute arbitrary code via a crafted 'sel' parameter.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if HP OpenView Network Node Manager is installedCheck for the presence of the OpenView Network Node Manager installation directory, typically found under C:\Program Files\HP\OpenView or similar locations. Use system inventory or installed software listings to confirm the product is present.Affected if HP OpenView Network Node Manager is installed on the system.
-
Determine the installed versionLocate the version information for the installed HP OpenView Network Node Manager. This is typically available in the product's about dialog, registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\HP\OpenView, or version information on the netmon.exe binary itself.Affected if The installed version is 7.01, 7.51, or 7.53.
-
Verify netmon.exe is presentLocate the netmon.exe executable in the OpenView installation directory, typically in the bin or similar subfolder. Use file system search or inspect the installation folder directly.Affected if The netmon.exe file exists in the OpenView installation directory.
-
Check if netmon.exe service is runningOpen Windows Services console (services.msc) or run 'sc query' command to check the status of the Network Node Manager service. Also verify if port 2711 (default netmon port) is listening using netstat or similar tool.Affected if The netmon.exe process or Network Node Manager service is currently running and listening on a network port.
-
Confirm ov.dll library versionLocate ov.dll in the OpenView installation directory, right-click the file, select Properties, and examine the Version tab to identify the file version.Affected if The ov.dll file version corresponds to the vulnerable versions (7.01, 7.51, or 7.53) of the product.
The system is affected if HP OpenView Network Node Manager versions 7.01, 7.51, or 7.53 are installed AND the netmon.exe service is running.

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.
From vendor dataApply HP vendor patches for this vulnerability or upgrade to a patched version of OpenView Network Node Manager; until patched, restrict network access to the netmon.exe service and implement network segmentation to reduce exposure.
