Medium CVSS 5.9

Due to a Missing Authorization Check in SAP Business Warehouse (Service API), an authenticated attacker could perform unauthorized actions via an affected RFC function module. Successful exploitation could enable unauthorized configuration and control changes, potentially disrupting request processing and causing denial of service. This results in low impact on integrity and high impact on availability, while confidentiality remains unaffected.

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.
