Vulnerabilities: April 2022 Highlights

[CVE-2022-28772] Denial of service (DOS) in SAP Web Dispatcher and SAP Netweaver (Internet Communication Manager) (SAP Note 3111311)

By overlong input values, an attacker may force overwrite of the internal program stack in SAP Web Dispatcher or Internet Communication Manager, which makes these programs unavailable. Patching your Kernel to the latest available version is the recommended fix.

Security updates for the browser control Google Chromium delivered with SAP Business Client (SAP Note 2622660)

From SAP Business Client 6.5 PL5 and above you can use the browser control Chromium for displaying HTML content within SAP Business Client. As this full browser control is delivered and can be installed with SAP Business Client, security corrections for this browser control are shipped with SAP Business Client patches. If the SAP Business Client release is not updated to the latest patch level, displaying web pages in SAP Business Client via this open-source browser control might lead to different vulnerabilities like memory corruption, information disclosure etc.

[CVE-2022-26105] Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Enterprise Portal (SAP Note 3163583)

SAP NetWeaver Enterprise Portal is susceptible to script execution attacks by an unauthenticated attacker due to improper sanitization of the user inputs while interacting on the Network. On successful exploitation, an attacker can view or modify information causing a limited impact on the confidentiality and integrity of the application.
