Official description
SAP NetWeaver Application Server ABAP and ABAP Platform does not perform necessary authorization checks for certain internal functionality. An attacker with low privileges could invoke affected functionality to execute arbitrary operating system commands on the underlying host. Successful exploitation could impact resources beyond the vulnerable component, resulting in a high impact on confidentiality, integrity and availability of the system.

The underlying weakness: Exposed Dangerous Method or Function
The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted.
How developers prevent this class of flaw
- If you must expose a method, make sure to perform input validation on all arguments, limit access to authorized parties, and protect against all possible vulnerabilities.
- Identify all exposed functionality. Explicitly list all functionality that must be exposed to some user or set of users. Identify which functionality may be: accessible to all users restricted to a small set of privileged users prevented from being directly accessible at all Ensure that the implemented code follows these expectations. This includes setting the appropriate access modifiers where applicable (public, private, protected, etc.) or not marking ActiveX controls safe-for-scripting.
