Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 83.59% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Microsoft Windows 10 Version 1507 and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

Windows Lightweight Directory Access Protocol (LDAP) Denial of Service Vulnerability

What

Windows Lightweight Directory Access Protocol (LDAP) Denial of Service Vulnerability

Why

The product reads data past the end, or before the beginning, of the intended buffer.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

What

Windows Lightweight Directory Access Protocol (LDAP) Denial of Service Vulnerability

Why

The product reads data past the end, or before the beginning, of the intended buffer.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.

Likely attack path
a network path → Out-of-bounds Read → disrupt the affected service
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction

Attack complexity
Low: no specialised conditions are recorded
Security boundary

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-125 ↗

CWE-125: Out-of-bounds Read. The product reads data past the end, or before the beginning, of the intended buffer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

NCSC-NL · Dutch · NCSC-2024-0470Kwetsbaarheden verholpen in Microsoft Windows

UPDATE: Onderzoekers hebben proof of concept (PoC) code gepubliceerd, waarmee de kwetsbaarheid met kenmerk CVE-2024-49113 kan worden aangetoond. Succesvol misbruik vereist dat de kwaadwillende toegang heeft tot zowel een DC met LDAP en een malafide server onder eigen controle. Hierdoor is misbruik niet eenvoudig te realiseren, maar neemt de kans erop wel toe. Succesvol misbruik resulteert in een Denial-of-Service van het kwetsbare systeem. Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade: - Denial-of-Service (DoS) - Uitvoer van willekeurige code (Gebruikersrechten) - Uitvoer van willekeurige code (Systeemrechten) - Verkrijgen van verhoogde rechten - Toegang tot gevoelige gegevens De ernstigste kwetsbaarheid heeft kenmerk CVE-2024-49112 toegewezen gekregen en bevindt zich in de LDAP-component van de Domain Controller. Een kwaadwillende kan de kwetsbaarheid misbruiken om zonder voorafgaande authenticatie uitvoer van willekeurige code mogelijk te maken middels een malafide LDAP-call. Succesvol misbruik vereist wel dat de kwaadwillende LAN-toegang tot de Domain Controller heeft. ``` Windows Kernel-Mode Drivers: |----------------|------|-------------------------------------| |
