SAP NetWeaver vulnerabilities

Version 7400.12.21.30308 of disp+work in SAP NetWeaver 7.40 allows remote attackers to cause a denial of service (resource consumption) via a crafted DIAG request.

SAP Netweaver 7.4 allows remote authenticated users to bypass an intended Unified Connectivity (UCON) access control list and execute arbitrary Remote Function Modules (RFM) by leveraging a connection created from earlier execution of an anonymous RFM included in a Communication Assembly.

The Cross-System Tools and Data Transfer Workbench in SAP NetWeaver have hardcoded credentials, allowing remote attackers to gain access via unspecified vectors.

The System Landscape Directory (SLD) in SAP NetWeaver allows remote attackers to modify information via vectors related to adding a system.

The XXE vulnerability in SAP Netweaver before version 7.01 allows an attacker to exploit external XML entities to gain access to system data.

A stack-based buffer overflow in SAP NetWeaver versions 7.0 through 7.5 allows remote attackers to cause a denial of service by sending a crafted packet to the SAPSTARTSRV port.

SAP NetWeaver and SAP Web Dispatcher do not properly validate certain fields in specially crafted requests handled by an internal protocol component. An unauthenticated attacker could send a malicious request that triggers a memory-handling error, causing the affected process to crash. Successful exploitation can therefore result in a high impact on the availability of the affected application. There is no impact on the confidentiality or integrity of the application.

Due to a missing authorization check in Application Server ABAP of SAP NetWeaver and ABAP Platform, an authenticated attacker could gain unauthorized access to sensitive system configuration information. This could expose security-relevant settings and internal system details, with low impact on confidentiality while integrity and availability remain unaffected.

SAP NetWeaver Application Server for ABAP and ABAP Platform writes sensitive session identifiers into a diagnostic trace when activated by a privileged user. An attacker with access to the trace can obtain identifiers allowing impersonation of legitimate users.
