Official description

SAP NetWeaver remote service for Xcelsius allows an attacker with network access and high privileges to execute arbitrary code on the affected system due to insufficient input validation and improper handling of remote method calls. Exploitation does not require user interaction and could lead to service disruption or unauthorized system control. This has high impact on integrity and availability, with no impact on confidentiality.

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.
