SAP NetWeaver Application Server ABAP, SAP NetWeaver Application Server Java, ABAP Platform, SAP Content Server 7.53 and SAP Web Dispatcher are vulnerable for request smuggling and request concatenation. An unauthenticated attacker can prepend a victim’s request with arbitrary data. This way, the attacker can execute functions impersonating the victim or poison intermediary Web caches. A successful attack could result in complete compromise of Confidentiality, Integrity and Availability of the system.

SAP ERP HCM Portugal – versions 600, 604, 608, does not perform necessary authorization checks for a report that reads the payroll data of employees in a certain area. Since the affected report only reads the payroll information, the attacker can neither modify any information nor cause availability impacts.

Due to insufficient encoding of user input, SAP NetWeaver allows an unauthenticated attacker to inject code that may expose sensitive data like user ID and password. These endpoints are normally exposed over the network and successful exploitation can partially impact confidentiality of the application.

Due to improper error handling in SAP NetWeaver Application Server Java – versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC, 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, an attacker could submit multiple HTTP server requests resulting in errors, such that it consumes the memory buffer. This could result in system shutdown rendering the system unavailable.
