CVE-2011-1728
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 OmniInet.exe in the Backup Client Service in HP OpenView Storage Data Protector 6.00, 6.10, and 6.11 allows remote attackers to execute arbitrary code via a malformed EXEC_BAR message.
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 confidenceA stack-based buffer overflow exists in OmniInet.exe, the Backup Client Service component of HP OpenView Storage Data Protector versions 6.00, 6.10, and 6.11. The vulnerability is triggered by sending a malformed EXEC_BAR message to the service, allowing remote attackers to overwrite stack memory and execute arbitrary code with the privileges of the affected service.

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 Data Protector installationCheck for the presence of the HP Data Protector installation directory, typically found under C:\Program Files\HP\Data Protector or similar paths depending on the operating system.Affected if HP Data Protector software is not installed on the system.
-
Identify the installed versionLocate the version information for HP Data Protector. Check installation logs, the product GUI, or registry entries under HKEY_LOCAL_MACHINE\SOFTWARE\HP\Data Protector for the version value.Affected if The installed version matches 6.00, 6.10, or 6.11 exactly.
-
Confirm OmniInet.exe is presentLocate the OmniInet.exe executable in the Data Protector installation directory, typically in the bin or etc subfolder.Affected if OmniInet.exe exists in the Data Protector installation path.
-
Check if Backup Client Service is runningVerify the OmniInet service status using the Windows Services console (services.msc) or the command 'sc query OmniInet' or look for the process listening on the Data Protector client port.Affected if The OmniInet service is running or the process is active on the system.
-
Assess network exposure of the serviceDetermine if the OmniInet service port (default TCP 5555 for Data Protector client) is listening on network interfaces and accessible from untrusted networks. Use 'netstat -an' or port scanning tools to identify exposed listening ports.Affected if The service port is bound to a network-facing interface and accessible from outside the local network.
A system is affected if HP Data Protector versions 6.00, 6.10, or 6.11 are installed with the OmniInet.exe (Backup Client Service) running and exposed to network access.

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 vendor-supplied patches for HP Data Protector or upgrade to an unaffected version. If patches are unavailable, restrict network access to the Backup Client Service port and consider disabling the service if not required.
