SAP Security Patch Day – February 2022
It seems like a bizarre coincidence that today, February 8th, is not only the second SAP Security Patch Day of the year but it is also Safe Internet Day! SAP is contributing to this by reporting serious security problems in the SAP Web Dispatcher that allow an attacker to attach malicious requests.
SAP fixes a series of HotNews and High vulnerabilities
The vulnerability described in 3123396 (Request smuggling and request concatenation in SAP NetWeaver, SAP Content Server, and SAP Web Dispatcher) requires immediate attention! The flaw gives the attacker the opportunity to impersonate the victim. Since SAP Web Dispatcher and SAP Internet Communication Manager (ICM) in SAP NetWeaver Application Server use the same source code, we strongly recommend that you also patch your systems that have an active instance of SAP ICM.
SecurityBridge customers benefit through updated signatures and tools which allow a quick validation of the Kernel and Web Dispatcher versions across all SAP systems in the landscape.

A similar vulnerability that “only” received priority High was also patched in SAP NetWeaver Application Server Java published in note 3123427 (HTTP Request Smuggling in SAP NetWeaver Application Server Java).
All SecurityBridge customers have the possibility to continuously check their attack surface. Knowing your attack surface is a critical advantage in the fight against cyberattacks. In this blog post, we explain why: Understand And Reduce The Attack Surface
