Memory Corruption in SAP NetWeaver Application Server ABAP

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: SAP SE

Description
Due to a Memory Corruption vulnerability in Application Server ABAP for SAP NetWeaver and ABAP Platform, an unauthenticated attacker could send specially crafted requests to the application. If processed by the application, these requests could trigger a memory corruption condition in the parsing routine, which could cause the affected processes to crash and restart. By repeatedly sending such requests, the attacker could cause a sustained denial of service, leading to a high impact on availability. Confidentiality and integrity remain unaffected.

Executive Summary

This is a Memory Corruption vulnerability in SAP NetWeaver and ABAP Platform's Application Server ABAP. An unauthenticated attacker can send specially crafted requests that trigger a memory corruption during parsing. This causes affected processes to crash and restart repeatedly, leading to a denial of service.

Detection Guidance

Monitor for repeated crashes or restarts of SAP NetWeaver or ABAP Platform processes. Check application logs for memory corruption errors or parsing routine failures. Use network traffic analysis tools to detect unusually high volumes of requests targeting the application server.

Impact Analysis

The vulnerability can cause sustained denial of service by crashing and restarting application processes repeatedly. This disrupts availability of the SAP system but does not affect confidentiality or integrity of data.

Compliance Impact

This vulnerability primarily impacts availability by causing denial of service through memory corruption in SAP NetWeaver and ABAP Platform. It does not affect confidentiality or integrity, which are key concerns for GDPR and HIPAA compliance. However, prolonged unavailability could disrupt access to personal or health data, potentially violating availability requirements in these regulations.

Mitigation Strategies

Apply the latest security patches from SAP as soon as they are available. Restrict network access to the application server ABAP using firewalls or network segmentation. Monitor and limit the rate of incoming requests to prevent denial of service conditions.
