The advisory for ABAP adresses a "[CVE-2020-6262] Code Injection vulnerability in Service Data Download". SAP Note 2835979 was released on 12.05.2020 and should be implemented during monthly patch process. The implementation demands a downtime. Component SV-SMG-SDD has a hot news risk of exploitation, according to the manufacturers security and response team.
Following the SAP Security Advisory team, a workaround does not exist.
The Service Data Download in an SAP Solution Manager Plugin allows an attacker to inject code that can be executed by the application. An attacker could thereby control the behavior of the application and the whole ABAP system leading to Code Injection.
The input is now properly sanitized to avoid code injection into RFC function modules. SecurityBridge customers will see the FM /SDF/GEN_FUNCS_FUNC_CALL added to the listener dealing with critical functions. Also without the patch being applied possible exploits will be identified.
