SAP NetWeaver Application Server ABAP and ABAP Platform - version KRNL64NUC, 7.22, KRNL64NUC 7.22EXT, KRNL64UC 7.22, KRNL64UC 7.22EXT, KRNL64UC 7.53, KERNEL 7.22, KERNEL, 7.53, KERNEL 7.77, KERNEL 7.81, KERNEL 7.85, KERNEL 7.89, KERNEL 7.54, KERNEL 7.92, KERNEL 7.93, under some conditions, performs improper authentication checks for functionalities that require user identity. An attacker can perform malicious actions over the network, extending the scope of impact, causing a limited impact on confidentiality, integrity and availability.

SAP NetWeaver ABAP Server and ABAP Platform - versions SAP_BASIS 700, 701, 702, 710, 711, 730, 731, 740, 750, 751, 752, 753, 754, 755, 756, 757, KERNEL 7.22, 7.53, 7.77, 7.81, 7.85, 7.89, KRNL64UC 7.22, 7.22EXT, 7.53, KRNL64NUC 7.22, 7.22EXT, creates information about system identity in an ambiguous format. This could lead to capture-replay vulnerability and may be exploited by malicious users to obtain illegitimate access to the system.

An attacker with no prior authentication could craft and send malicious script to SAP GUI for HTML within Fiori Launchpad, resulting in reflected cross-site scripting attack. This could lead to stealing session information and impersonating the affected user.

An attacker with basic business user privileges could craft and upload a malicious file to SAP NetWeaver Application Server ABAP, which is then downloaded and viewed by other users resulting in a stored Cross-Site-Scripting attack. This could lead to information disclosure including stealing authentication information and impersonating the affected user.

SAP startservice - of SAP NetWeaver Application Server ABAP, Application Server Java, ABAP Platform and HANA Database - versions KERNEL 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, 7.88, KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC 7.22, 7.22EXT, 7.49, 7.53, SAPHOSTAGENT 7.22, - on Unix systems, s-bit helper program sapuxuserchk, can be abused physically resulting in a privilege escalation of an attacker leading to low impact on confidentiality and integrity, but a profound impact on availability.

SAP NetWeaver, ABAP Platform and SAP Host Agent - versions KERNEL 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, 7.88, 8.04, KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC 7.22, 7.22EXT, 7.49, 7.53, 8.04, SAPHOSTAGENT 7.22, allows an authenticated user to misuse a function of sapcontrol webfunctionality(startservice) in Kernel which enables malicious users to retrieve information. On successful exploitation, an attacker can obtain technical information like system number or physical address, which is otherwise restricted, causing a limited impact on the confidentiality of the application.

Depending on the configuration of the route permission table in file 'saprouttab', it is possible for an unauthenticated attacker to execute SAProuter administration commands in SAP NetWeaver and ABAP Platform - versions KERNEL 7.49, 7.77, 7.81, 7.85, 7.86, 7.87, 7.88, KRNL64NUC 7.49, KRNL64UC 7.49, SAP_ROUTER 7.53, 7.22, from a remote client, for example stopping the SAProuter, that could highly impact systems availability.

SAP Host Agent, SAP NetWeaver and ABAP Platform allow an attacker to leverage logical errors in memory management to cause a memory corruption.

The Web administration UI of SAP Web Dispatcher and the Internet Communication Manager (ICM) does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.

SAP NetWeaver AS ABAP and ABAP Platform, versions - KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, KRNL64UC 8.04, 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.53, KERNEL 8.04, 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.53, 7.77, 7.81, 7.84, allows an attacker to send overlong content in the RFC request type thereby crashing the corresponding work process because of memory corruption vulnerability. The work process will attempt to restart itself after the crash and hence the impact on the availability is low.
