CVE-2024-42451 — A vulnerability in Veeam Backup & Replication allows low-privileged users to leak all saved credentials in plaintext

High CVSS 7.7

A vulnerability in Veeam Backup & Replication allows low-privileged users to leak all saved credentials in plaintext. This is achieved by calling a series of methods over an external protocol, ultimately retrieving the credentials using a malicious setup on the attacker's side. This exposes sensitive data, which could be used for further attacks, including unauthorized access to systems managed by the platform.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
