Highlights

On December Patch Day SAP presents 6 high-severity Notes with 4 of them rated as HotNews.

Today we start our monthly digest with 2974774 Security Note – Missing Authentication Check In SAP NetWeaver AS JAVA (P2P Cluster Communication) – with the highest CVSS Score of 10. An unauthenticated attacker could invoke access to system administration functions or shut down the system completely with no privileges required through insecure P2P Cluster Communication services. We suggest special attention to applying the presented solution.

BusinessObjects Business Intelligence Platform receives attention with 2989075 Security Note due to Missing XML Validation. An attacker with basic privileges can inject some arbitrary XML entities which result in a potential Server Side Request Forgery or denial-of-service. The CVSS Score of this Note is 9.6.

The next HotNews is Security Note 2983367Code Injection vulnerability in SAP Business Warehouse (Master Data Management) and SAP BW4HANA. Without requiring any user interaction, the potential attacker can submit a crafted request to generate and execute code allowed by Master Data Management. The CVSS Score is 9.1.

The last HotNews for today is Code Injection in SAP AS ABAP and S/4 HANA (DMIS) – Security Note 2973735 with a CVSS Score of 9.1. Due to a lack of input validation, the potential attacker can inject malicious ABAP code, which will be saved persistently in a report in the ABAP repository.
