Resource Exhaustion in SAP NetWeaver Application Server

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: SAP SE

Description
SAP NetWeaver Application Server ABAP, ABAP Platform, and SAP Web Dispatcher do not sufficiently handle resource consumption when processing certain requests. An unauthenticated attacker could send specially crafted requests to the affected component, causing excessive resource utilization and service disruption. This results in a high impact on availability. There is no impact on confidentiality and integrity.

Executive Summary

SAP NetWeaver Application Server ABAP, ABAP Platform, and SAP Web Dispatcher have a flaw where they do not properly manage resource consumption when handling certain requests. An attacker can exploit this by sending specially crafted requests, leading to excessive resource usage and service disruption. This primarily affects system availability without impacting data confidentiality or integrity.

Detection Guidance

Monitor network traffic for unusually high request volumes targeting SAP NetWeaver components. Check server resource usage (CPU, memory) for spikes during normal operations. Use SAP logs to identify excessive request patterns or errors in ABAP, ABAP Platform, or Web Dispatcher logs.

Impact Analysis

This vulnerability can cause service outages or degraded performance for systems running SAP NetWeaver, ABAP Platform, or SAP Web Dispatcher. It may lead to downtime, affecting business operations that rely on these systems. Since it requires no authentication, any external or internal user could potentially trigger the issue.

Compliance Impact

This vulnerability primarily impacts availability by causing excessive resource utilization and service disruption. It does not affect confidentiality or integrity, which are key concerns for GDPR and HIPAA compliance. However, prolonged service disruption could indirectly impact compliance by hindering access to personal or health data, potentially violating availability requirements in these regulations.

Mitigation Strategies

Apply SAP security notes or patches referenced in SAP Note 3805681. Configure rate limiting or request throttling on SAP NetWeaver components. Restrict access to SAP systems via firewalls or network segmentation to limit exposure.
