Official description

Due to a Missing Authorization Check vulnerability in SAP S/4 HANA Private Cloud (Financials General Ledger), an authenticated attacker with authorization limited to a single company code could read sensitive data and post or modify documents across all company codes. Successful exploitation could result in a high impact to confidentiality and a low impact to integrity, while availability remains unaffected.

The underlying weakness: Asymmetric Resource Consumption (Amplification)

The product does not properly control situations in which an adversary can cause the product to consume or produce excessive resources without requiring the adversary to invest equivalent work or otherwise prove authorization, i.e., the adversary's influence is asymmetric.

How developers prevent this class of flaw

  • An application must make resources available to a client commensurate with the client's access level.
  • An application must, at all times, keep track of allocated resources and meter their usage appropriately.
  • Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
