CVE-2011-2399
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 · uneditedUnspecified vulnerability in the Media Management Daemon (mmd) in HP Data Protector 6.11 and earlier allows remote attackers to cause a denial of service via unknown vectors.
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 · moderate confidenceDenial of service vulnerability in HP Data Protector's Media Management Daemon (mmd) allows remote attackers to crash the service, causing availability disruption. The vulnerability affects versions 6.11 and earlier, with exploitation vectors remaining unspecified in available documentation.

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 HP Data Protector versionQuery the installed HP Data Protector version using the system's package manager, the HP Data Protector installation directory, or the 'omnisv' command if available. Common locations include /opt/HP-OM and program files on Windows.Affected if The installed version is 6.10 or 6.11, or any version <= 6.11 (the affected range).
-
Verify Media Management Daemon (mmd) presenceCheck if the Media Management Daemon process (mmd) is running. On Unix systems, use 'ps -ef | grep mmd' or check /opt/HP-OM/installation_dir/bin/mmd. On Windows, check the service list for 'HP Data Protector Media Management Daemon'.Affected if The mmd process is running and exposed to network access.
-
Check network exposure of mmd serviceIdentify the listening port for mmd (typically UDP port 6878 or 6879 for Media Management) using 'netstat -anp' or 'ss -tlnp'. Determine if the service is bound to a non-loopback interface or is accessible from network segments.Affected if The mmd service listens on a routable IP address rather than localhost only.
-
Review firewall rules for mmd portsInspect host-based firewall rules (iptables on Linux, Windows Firewall) and network perimeter filters to determine if inbound traffic to mmd ports is permitted from untrusted networks.Affected if Firewall rules allow inbound access to mmd ports from arbitrary network sources.
You are affected if HP Data Protector version 6.10 or 6.11 (or any version <= 6.11) is installed AND the Media Management Daemon (mmd) is running with network accessibility.

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 dataIsolate the Media Management Daemon behind a firewall or restrict network access; verify if vendor patches exist for HP Data Protector 6.11 and apply updates; consider upgrading to a supported version if available.
