Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.36% 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.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Veeam Backup & Replication 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: As exposure requiresRemediation target: Within 365 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.

01

What, why and how

A vulnerability exists where a low-privileged user can exploit insufficient permissions in credential handling to leak NTLM hashes of saved credentials. The exploitation involves using retrieved credentials to expose sensitive NTLM hashes, impacting systems beyond the initial target and potentially leading to broader security vulnerabilities.

What

A vulnerability exists where a low-privileged user can exploit insufficient permissions in credential handling to leak NTLM hashes of saved credentials. The exploitation involves using retrieved credentials to expose sensitive NTLM hashes, impacting systems beyond the initial target and potentially leading to broader security vulnerabilities.

Why

The application performs an authorisation check, but it does not correctly enforce the required permission boundary.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

CWE-863 ↗

CWE-863: Incorrect Authorization. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.

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

Official advisory ↗
NCSC-NL · Dutch · NCSC-2024-0463Kwetsbaarheden verholpen in Veeam Backup & Replication

De kwetsbaarheden in Veeam Backup & Replication stellen laaggeprivilegieerde gebruikers in staat om op afstand code uit te voeren, opgeslagen referenties in platte tekst te extraheren, een agent in servermodus te starten, configuraties binnen de virtuele infrastructuur te manipuleren, en kritieke configuratie-instellingen te exploiteren. Dit kan leiden tot ongeautoriseerde toegang tot gevoelige systemen en gegevens, privilege-escalatie, en zelfs gegevensverlies. De ernst van deze kwetsbaarheden vereist een zorgvuldige beoordeling van gebruikersrechten en configuratiebeheerpraktijken door organisaties die deze software gebruiken.

Fixed
Action
Apply the fixed release for the affected product branch as recorded by Veeam. Validate the exact product and build in the linked advisory before deployment.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.

    12.2 ≤ 12.2 · Fixed: No fixed version is explicitly recorded in the structured CVE data.
    After
    12.2 ≤ 12.2 · Fixed: The Veeam Backup & Replication vulnerabilities discussed in this section are related to the ability of an authenticated malicious user with a limited role (Viewer/Operator) to perform certain actions that are normally only possible with administrative privileges on the backup server. To mitigate these vulnerabilities until the backup server can be upgraded to version 12.3, simply remove untrusted and/or unnecessary users from the Users and Roles settings on the backup server for the time being.; The vulnerability disclosed in this section affects Veeam Agent for Microsoft Windows 6.2 and all earlier version 6 builds.; Veeam Backup & Replication 12.3 (build 12.3.0.310)
