Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 38.43% for the current model date.

Compensating controls

  • 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. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  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.

01

What, why and how

Veeam Backup Enterprise Manager allows unauthenticated users to log in as any user to enterprise manager web interface.

What

Veeam Backup Enterprise Manager allows unauthenticated users to log in as any user to enterprise manager web interface.

Why

The affected component does not establish the requesting party's identity reliably before granting access.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.
None recorded

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

Likely attack path
a network path → Improper Authentication → cause the confidentiality, integrity or availability impact described by the vendor

None: unauthenticated exploitation is possible

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-287 ↗

CWE-287: Improper Authentication. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Common Vulnerability Scoring System 3.0: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

Veeam Backup Enterprise Manager (VBEM)에서 발생하는 인증 우회 취약점(CVE-2024-29849) [1]

Official advisory ↗
NCSC-NL · Dutch · NCSC-2024-0232Kwetsbaarheden verholpen in Veeam Backup Enterprise Manager

Een kwaadwillende kan de kwetsbaarheden misbruiken om zonder voorafgaande authenticatie toegang te krijgen tot gebruikersaccounts die actief zijn binnen de Enterprise Manager en zo toegang te krijgen tot gevoelige gegevens binnen de context van het overgenomen account, en mogelijk willekeurige code uit te voeren met rechten van het overgenomen account. Ondersoekers hebben Proof-of-Concept-code (PoC) gepubliceerd waarmee de kwetsbaarheid kan worden aangetoond. De werking van de PoC vereist echter dat een kwaadwillende een eigen server in de infrastructuur inbrengt, welke valselijk de Single-Sign-on overneemt, waarmee de kwaadwillende administratorrechten kan krijgen op de web-interface van Backup Enterprise Manager.
