SAP on Tuesday announced the release of eight new security notes as part of its June 2023 Security Patch Day, including two notes that address high-severity vulnerabilities. Five other notes were updated.
The most important of SAP’s new security notes resolves a stored cross-site scripting (XSS) bug in UI5 Variant Management.
Tracked as CVE-2023-33991 (CVSS score of 8.2), the issue can be exploited to gain user-level access to the UI5 Varian Management application and compromise confidentiality, integrity, and availability.
The second high-severity flaw is a missing authentication issue in Plant Connectivity and Production Connector for Digital Manufacturing, tracked as CVE-2023-2827 (CVSS score of 7.9). It can be exploited to connect to a vulnerable application without a valid JSON Web Token (JWT).
According to enterprise application security firm Onapsis, “in order to fully patch this vulnerability, both components must be patched and JWT signature validation must be configured from the Cloud Connector settings.”
This week, SAP also updated two notes dealing with high-severity bugs in Knowledge Warehouse (CVE-2021-42063) and SAPUI5 (CVE-2023-30743). The updates only contain “minor textual or structural” changes from the previous notes, Onapsis says.
Of the eight new and updated medium-severity security notes that SAP released this week, six deal with XSS flaws in NetWeaver, CRM ABAP (Grantor Management), CRM (WebClient UI), and BusinessObjects.
The other two notes resolve an information disclosure bug in S/4HANA and an SQL injection issue in Master Data Synchronization.
The last security note released on SAP’s June 2023 Security Patch Day resolves a low-severity denial-of-service (DoS) vulnerability in NetWeaver (Change and Transport System).
