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 if HPE iLO Amplifier Pack is deployedCheck for the HPE iLO Amplifier Pack service on your network or on the host system. This is typically a dedicated appliance or virtual machine used for firmware management of HPE servers.Affected if The system has HPE iLO Amplifier Pack installed and running.
-
Determine the installed versionAccess the HPE iLO Amplifier Pack web interface and navigate to the About or System Information section to view the firmware version. Alternatively, use the command line interface if available and check the installed package version.Affected if The displayed version number is lower than 1.90.
-
Verify remote management access is enabledCheck the iLO Amplifier Pack network settings to confirm whether remote management interfaces are accessible from network segments. Look for settings related to remote access, HTTPS management interface, or API access.Affected if Remote management access is enabled and the system is reachable over the network.
-
Check for exposed management portsScan the system or appliance hosting iLO Amplifier Pack for open management ports such as 443, 8443, or other HTTPS-based management ports that could indicate the web interface is exposed.Affected if Management ports are open and accessible from untrusted networks.
You are affected if HPE iLO Amplifier Pack is running with a version lower than 1.90 and its management interface is network-accessible.
