On April Patch Day SAP presents 10 high-severity Notes with 5 of them rated as HotNews.
The patch for today is rich for all kinds of severity notes, however, we will highlight the most critical HotNews, starting with 2904480 – Missing XML Validation vulnerability in SAP Commerce – with a CVSS Score of 9.3. SAP Commerce does not process XML input securely in certain REST XML APIs. This affects the confidentiality and partial availability of SAP Commerce.
The next Note to describe will be 2863731 – Deserialization of Untrusted Data in SAP Business Objects Business Intelligence Platform (CR .Net SDK WebForm Viewer) – with a CVSS Score of 9.1. Crystal reports web form viewer allows an attacker with basic authorization to perform a deserialization attack in the application, which may lead to code execution upon it. To manage the vulnerability, we suggest applying the Solution steps presented for Business Objects platform security.
SAP NetWeaver also received the fix in Note 2896682 – Directory Traversal vulnerability in SAP NetWeaver (Knowledge Management) – with a CVSS Score of 9.1. An attacker was allowed to overwrite, delete, or corrupt arbitrary files on the remote server through the lack of path validation of the information provided by users.
Security Note 2808158 receives an ‘Update 2’ as the Note 2839864 – OS Command Injection vulnerability in SAP Diagnostics Agent – with a CVSS Score of 9.1. The original correction did not cover all scenarios, so the OSS note 2839864 corrects these additional ones to exclude the possibility of arbitrary code execution.
