CVE-2011-1731
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_INTEGUTIL 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.

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.
-
Check if HP OpenView Storage Data Protector is installedLook for the Data Protector installation directory, typically under C:\Program Files\HP\Data Protector or C:\hp\Data Protector. On Unix/Linux systems, check /opt/hp/dataprotector or /usr/local/hp/dataprotector.Affected if The software is not found, meaning the product is not installed and the system is not affected.
-
Identify the installed Data Protector versionCheck the version of omniinet.exe or look for version information in the installation directory. The executable is typically located in the \bin\ folder of the Data Protector installation. Run 'omniinet.exe -version' or check file properties of the OmniInet.exe binary.Affected if The installed version is exactly 6.00, 6.10, or 6.11, matching the affected versions listed.
-
Verify the Backup Client Service (OmniInet.exe) is runningOn Windows, open Services console and look for 'HP OpenView Storage Data Protector' or 'OmniInet' service. On Unix/Linux, run 'ps -ef | grep omniinet' to check if the process is active.Affected if The OmniInet.exe service is running, making the vulnerable component active on the system.
-
Determine if the Backup Client Service is network accessibleCheck if the OmniInet service is listening on network ports (default ports are 5555 for OmniInet). Run 'netstat -an | grep 5555' or use a port scanner to test connectivity to the service from untrusted networks.Affected if The service is exposed to network access, particularly to untrusted networks, increasing the risk of remote exploitation.
A system is affected if HP OpenView Storage Data Protector versions 6.00, 6.10, or 6.11 are installed with the OmniInet.exe Backup Client Service running and network-accessible.

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 patches from HP for Data Protector or upgrade to a patched version. If patches are unavailable, consider network segmentation to limit exposure of the Backup Client Service to untrusted networks.
