Hot News Note 2622660 includes critical security updates for web browser controls delivered with SAP Business Client. The Client provides a unified environment for SAP applications including Fiori, SAP GUI, and Web Dynpro.  It supports browser controls from Internet Explorer (IE) and Chrome for displaying HTML content. Security corrections for the WebBrowser control of the .NET framework in IE are delivered directly by Microsoft. Unlike IE, the browser control for Chrome is embedded in SAP Business Client using the open source Chromium Embedded Framework (CEF). Security fixes are provided by the Chromium project and delivered by SAP through periodic Security Notes.  Note 2622660 was updated for multiple high-risk vulnerabilities addressed by Chromium release 70.0.3538.

Note 2681280 patches a critical remote code execution vulnerability in SAP HANA Streaming Analytics (HSA). The vulnerability impacts the open source Java-based Spring Framework library used by HSA. The note carries a CVSS score of 9.9/10.

Note 2701410 deals with a high-risk directory traversal vulnerability that could be exploited by attackers to access, modify or corrupt files on hosts supporting SAP Disclosure Management.

Note 2693083 removes transaction ZPTTNO_TIME from the standard role SAP_PS_RM_PRO_RECMANAGER. The transaction could be abused to escalate privileges in CRM Records and Case Management.

Hot News note 2654905 patches a high risk information disclosure vulnerability in the SAP BusinessObjects BI Suite. The execution of specific CMS queries on the Central Management Server could bypass authorization checks and lead to the leakage of sensitive data. The vulnerability scores 9.8/ 10 based on the Common Vulnerability Scoring System v3 (CVSS).  Patches for BI 4.1 SP 10-12 and 4.2 SP 4-6 referenced in the Note enable authorization checks for vulnerable CMS queries.

Note 2699726 provides corrections to remove a missing network isolation error in SAP’s Open Source project Gardener.  Gardener is an API server that provides Kubernetes clusters for several SAP products. SAP is responsible for security updates for Gardener instances and Gardener managed Kubernetes clusters at SAP. Note 2699726 applies only to Gardener stakeholders in the Open Source Community who operate their own Gardener installations. The Note recommends upgrading to Gardener release 0.12.4 or higher in order to prevent admins in shoot clusters from compromising seed clusters or other shoot clusters.

Note 2696962 provides instructions for dealing with a Denial of Service (DoS) vulnerability in the SQLite database engine of SAPFoundation. SQLite is embedded in the SAP Cloud Platform SDK for iOS 2.0 SP02 and 3.0.

Note 2674215 provides corrections for patching a stack overflow vulnerability that could be exploited by attackers to provoke a denial of service in SAP Plant Connectivity.

Note 2681207 patches a high-risk missing XML validation vulnerability in Extended Application Services (XS) in SAP HANA. The OData parser in HANA XS does not sufficiently validate XML input from users. This can lead to the processing of malicious code that could provoke a denial of service in the database server. The vulnerability can be exploited if applications using OData services are enabled on HANA XS. If authentication is not enforced for an enabled application using OData, an anonymous attacker can exploit the vulnerability. The attacker needs network access to the HTTP/HTTPs port of the SAP HANA database XS engine classic model. The vulnerability can be fixed by applying the software packages listed in note 2681207. Alternatively, you can limit network access to the XS classic server running in the tenant databases of a multitenant system. The default port range is 30040 – 30997. It is also recommended to enforce authentication for applications using OData services via HANA XS.

Note 2644279 deals with a similar high-risk missing XML validation vulnerability in a component of the BEx Web Java Runtime in Business Warehouse. The issue is specific to PDF ALV Export.

Note 2392860 removes transaction ZPTTNO_TIME from the standard roles SAP_PS_RM_PRO_ADMIN and SAP_PS_ RM_PRO_REVIEWER in SAP CRM Case Management. The transaction could be abused to escalate privileges.

Other high priority notes include note 2670284 which updates logging functions in Crystal Reports and Business One for HANA to prevent the disclosure of sensitive information, and note  2449974 which introduces authorization check V_VBKA_VKO for specific Sales Support APIs in ECC Sales and Distribution.

There were several high priority Security Notes released in August for vulnerabilities impacting multiple Business Intelligence applications. Note 2569748 patches an XML External Entity vulnerability in Crystal Reports for Enterprise. Note 2614229 deals with a memory corruption vulnerability in the BOBJ platform that can be triggered by a buffer overflow. Note 2644154 provides corrections for a SQL injection vulnerability in the BI Launchpad for Web Intelligence that could be exploited to read sensitive data.

A similar SQL injection vulnerability is addressed in the MaxDB database by note 2660005. The solution includes removing unnecessary privileges for DBM operators responsible for managing databases.

Notes 2655250 and 2155614 patch missing authorization checks in the MDM Catalog of Supplier Relationship Management (SRM) and components of ERP Sales and Distribution.  

Note 2201710 includes instructions for responding to Logjam and similar vulnerabilities in SAP products using OpenSSL. Logjam involves downgrading vulnerable TLS connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. Note 2201710 adds protection for TLS clients by rejecting handshakes with DH parameters shorter than 768 bits.
