CVE-2024-8321
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 · uneditedMissing authentication in Network Isolation of Ivanti EPM before 2022 SU6, or the 2024 September update allows a remote unauthenticated attacker to isolate managed devices from the network.
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 confidenceIvanti Endpoint Manager (EPM) contains a missing authentication vulnerability in its Network Isolation feature. An unauthenticated remote attacker can exploit this flaw to isolate managed devices from the network, effectively disconnecting endpoints without requiring any credentials or legitimate administrative access.

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 Ivanti Endpoint Manager installationCheck for Ivanti EPM service or process on the server: Run 'Get-Service | Where-Object {$_.DisplayName -like "*Ivanti*"}' or check Program Files for 'Ivanti' folder. Also check Windows Services for 'Ivanti Endpoint Manager' service.Affected if Ivanti Endpoint Manager is installed on this system
-
Determine installed Ivanti EPM versionCheck the version via registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID} or examine the CoreServer.exe file properties in the EPM installation directory.Affected if The installed version is any release of 2022, 2024, or any version prior to 2022
-
Verify Network Isolation feature is enabledAccess Ivanti EPM console, navigate to Tools > Network Tools > Network Isolation, or check registry key HKLM\SOFTWARE\LANDesk\LDBSECURE\Settings\NetworkIsolation for enabled state.Affected if Network Isolation feature is configured and enabled in the EPM environment
-
Check network exposure of EPM management interfaceReview firewall rules and network accessibility of ports used by EPM (typically ports 80, 443, 3126, 3127). Identify if the EPM server is directly accessible from untrusted networks.Affected if The EPM server management interface or Network Isolation functionality is exposed to unauthenticated network access
Environment is affected if Ivanti EPM version is 2022, 2024, or older than 2022 AND the Network Isolation feature is enabled with the management interface accessible to unauthenticated network attackers.

dbcve · scoped2022
Apply the vendor-supplied patch: either update to Ivanti EPM 2022 SU6 or later, or deploy the 2024 September update. Network isolation functionality should be tested post-patch to confirm legitimate administrative controls remain intact.
2022 SU6 (Service Update 6) or later for 2022 branch; September 2024 update or later for 2024 branch
- Identify the current version of Ivanti Endpoint Manager (EPM) by checking the administration console or system information
- If running Ivanti EPM 2022.x (any version), upgrade to version 2022 SU6 (Service Update 6) or later
- If running Ivanti EPM 2024.x (any version), apply the September 2024 update or later
- After upgrading, verify the version change was successful in the EPM console
- Test the Network Isolation functionality to confirm it operates correctly post-upgrade
