CVE-2013-1282
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 · uneditedThe 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 confidenceA 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.

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 Active Directory Domain Services role is installedOpen Server Manager, go to Manage > Add Roles and Features, or run 'Get-WindowsFeature AD-Domain-Services' in PowerShell on the serverAffected if The AD-Domain-Services role is installed and the server is functioning as a Domain Controller
-
Check if AD LDS (Active Directory Lightweight Directory Service) is installedRun 'Get-WindowsFeature ADLDS' in PowerShell, or check for the 'ADAM' Windows service in Services.mscAffected if AD LDS instance(s) are installed on the system
-
Verify if LDAP services are listening on the networkRun '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
-
Check for running LDAP service processesOpen Task Manager or run 'Get-Process | Where-Object {$_.ProcessName -match "lsass|ntds"}' to verify Directory Services are activeAffected if The lsass.exe or ntds.exe process is running, indicating Active Directory services are active
-
Confirm LDAP query handling is enabledCheck LDAP configuration in registry under HKLM\SYSTEM\CurrentControlSet\Services\NTDS\Parameters or via 'dsquery *' commandsAffected 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.

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 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.
