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.
-
Verify HP OpenView Network Node Manager is installedCheck for the presence of HP OpenView Network Node Manager in the system by looking for its installation directory, typically under C:\Program Files\HP\OpenView\ or C:\HP\OpenView\, or search for the nnmRptConfig.exe file on the system.Affected if The product is not installed or nnmRptConfig.exe is not found on the system.
-
Identify the installed versionLocate the version information for HP OpenView Network Node Manager. Check the installation directory for version files, or right-click on nnmRptConfig.exe and view Properties > Details for the File Version. Alternatively, check the Windows Registry under HKLM\SOFTWARE\HP\OpenView\NodeManager for the Version key.Affected if The version is 7.51 or 7.53, indicating the system is running an affected version.
-
Confirm nnmRptConfig.exe existsSearch for the file nnmRptConfig.exe in the HP OpenView installation directory, typically found in the \bin\ or \lbin\ subdirectory.Affected if The executable exists on the system, indicating the vulnerable component is present.
-
Check if the reporting service is exposedReview network exposure of the nnmRptConfig.exe component. Check if the HP OpenView web server or reporting interface is accessible from the network. Review firewall rules and access controls around ports used by HP OpenView (commonly port 80, 443, or 3443).Affected if The service is network-accessible, meaning the format string vulnerability can be exploited remotely.
A system is affected if HP OpenView Network Node Manager versions 7.51 or 7.53 are installed, the nnmRptConfig.exe component exists, and it is accessible for exploitation.
