Denial of service (DOS) in SAP NetWeaver and ABAP platform
Impact on Business
A remote attacker can block all work processes of an SAP System running on SAP NetWeaver AS ABAP. This has a very high negative impact on the availability of the system and its business applications.
Vulnerability Details
A certain remote-enabled function module, from /SDF/EWA function group, allows non-administrative authenticated users to set a parameter with big values that will cause an infinite loop. A malicious user could call the function module multiple times from external in parallel to block several or all work processes and thus making the system unavailable. The vulnerable function module is shipped with the SAP_BASIS software component and is included in the SAP Solution Tools Plug-In (ST-PI) application component (SV-SMG-SDD).
Solution
SAP has released SAP Note 3453170 which provides patched versions of the affected components.
