Summary
Several SAP NetWeaver products, including the Application Server ABAP and Java, along with the ABAP Platform and SAP Web Dispatcher, are vulnerable to a request smuggling issue. An unauthenticated attacker can manipulate HTTP requests by prepending arbitrary data to a victim's request. This technique enables the attacker to execute functions on behalf of the victim or to poison web caches, compromising the overall security of the system. As a result, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of affected SAP systems.
