description

SAP Gateway is affected when its default access control list assigns excessive privileges to external network clients. An unauthenticated attacker with network access may be treated as an internal application server and perform unauthorized actions. Exposure requires network reachability to the affected SAP Gateway.

mitigation

Replace or restrict the default access control list so external network clients cannot be classified as internal application servers. Limit network access to SAP Gateway to trusted systems until vendor remediation is applied.
