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 · unedited
The LDAP service in Microsoft Active Directory, Active Directory Application Mode (ADAM), Active Directory Lightweight Directory Service (AD LDS), and Active Directory Services allows remote attackers to cause a denial of service (memory consumption and service outage) via a crafted query, aka "Memory Consumption Vulnerability."

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 confidence

A memory consumption vulnerability exists in the LDAP service of Microsoft Active Directory, Active Directory Application Mode (ADAM), Active Directory Lightweight Directory Service (AD LDS), and Active Directory Services. Remote attackers can send crafted LDAP queries that cause excessive memory consumption, leading to denial of service and service outage.

MitigationApply the Microsoft security update for this vulnerability. Additionally, consider network-level controls such as restricting LDAP access to trusted IPs and implementing query rate limiting to reduce attack surface.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Active Directory Domain Services role is installed
    Open Server Manager, go to Manage > Add Roles and Features, or run 'Get-WindowsFeature AD-Domain-Services' in PowerShell on the server
    Affected if The AD-Domain-Services role is installed and the server is functioning as a Domain Controller
  2. Check if AD LDS (Active Directory Lightweight Directory Service) is installed
    Run 'Get-WindowsFeature ADLDS' in PowerShell, or check for the 'ADAM' Windows service in Services.msc
    Affected if AD LDS instance(s) are installed on the system
  3. Verify if LDAP services are listening on the network
    Run 'netstat -an | findstr "389\|636"' or use PortQry.exe to query ports 389 (LDAP) and 636 (LDAPS)
    Affected if LDAP ports are open and listening, indicating the LDAP service is exposed
  4. Check for running LDAP service processes
    Open Task Manager or run 'Get-Process | Where-Object {$_.ProcessName -match "lsass|ntds"}' to verify Directory Services are active
    Affected if The lsass.exe or ntds.exe process is running, indicating Active Directory services are active
  5. Confirm LDAP query handling is enabled
    Check LDAP configuration in registry under HKLM\SYSTEM\CurrentControlSet\Services\NTDS\Parameters or via 'dsquery *' commands
    Affected if LDAP query handling is enabled and the directory service is operational

The system is affected if it runs any Active Directory service (AD DS, AD LDS, or ADAM) with LDAP listening on the network, as all versions contain the vulnerability.
