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 the stringToSeconds function in ovutil.dll in ovwebsnmpsrv.exe in HP OpenView Network Node Manager (OV NNM) 7.51 and 7.53 allows remote attackers to execute arbitrary code via large values of variables to jovgraph.exe.

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 the stringToSeconds function in ovutil.dll within ovwebsnmpsrv.exe in HP OpenView Network Node Manager versions 7.51 and 7.53 allows remote attackers to execute arbitrary code via crafted large values passed to jovgraph.exe.

MitigationApply HP vendor patches for OpenView NNM 7.51/7.53 or upgrade to a patched version to remediate this critical buffer overflow vulnerability.

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 HP OpenView Network Node Manager installation
    Search for the OpenView NNM installation directory, typically found in C:\hp\OpenView\Network Node Manager or C:\Program Files\HP\OpenView\Network Node Manager. Check for the presence of the 'ovwebsnmpsrv.exe' and 'jovgraph.exe' executables in the installation folder.
    Affected if The software is installed and the vulnerable executables (ovwebsnmpsrv.exe, jovgraph.exe) are present on the system.
  2. Determine the installed version of OpenView NNM
    Check the version of ovwebsnmpsrv.exe or the main NNM installation. Right-click on ovwebsnmpsrv.exe, select Properties, and view the Version tab. Alternatively, check the README or version.info file in the installation directory.
    Affected if The installed version is 7.51 or 7.53 specifically.
  3. Verify presence of vulnerable ovutil.dll
    Locate ovutil.dll in the installation directory, typically in the bin or system32 subfolder within the OpenView NNM directory. Check the file version by right-clicking the DLL and viewing Properties > Version.
    Affected if ovutil.dll exists in the NNM installation directory with a version corresponding to NNM 7.51 or 7.53.
  4. Check if ovwebsnmpsrv service is running
    Open Windows Services (services.msc) and look for 'HP OpenView Network Node Manager Web Server' or check if ovwebsnmpsrv.exe process is running via Task Manager.
    Affected if The ovwebsnmpsrv.exe service or process is active, enabling the attack vector through the web interface.
  5. Check if jovgraph.exe is accessible
    Verify jovgraph.exe exists in the cgi-bin or cgi directory under the OpenView NNM web root (typically in the 'web\/cgi' subdirectory of the installation). This executable handles the stringToSeconds function calls.
    Affected if jovgraph.exe is present in the cgi-bin directory, making the stringToSeconds buffer overflow exploitable via crafted requests.

A system is affected if HP OpenView Network Node Manager versions 7.51 or 7.53 are installed with the ovwebsnmpsrv web service running and jovgraph.exe accessible, as this configuration enables exploitation of the ovutil.dll buffer overflow.
