Memory Corruption in SAP NetWeaver ABAP Platform

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: SAP SE

Description
Due to improper RFC protocol validation in the SAP Kernel used by the Application Server ABAP of SAP NetWeaver and ABAP Platform, an unauthenticated attacker can send a crafted RFC request that exploits logical errors in memory management, leading to memory corruption. This could lead to a high impact on confidentiality and integrity with low impact on availability of the application.

Executive Summary

This vulnerability is due to improper RFC protocol validation in the SAP Kernel used by SAP NetWeaver and ABAP Platform. An unauthenticated attacker can send a crafted RFC request that exploits memory management errors, leading to memory corruption. This may result in high impact on confidentiality and integrity with low impact on availability.

Detection Guidance

Detection requires monitoring for unusual memory corruption patterns or RFC request anomalies. Check SAP logs for failed RFC requests or memory errors. Use network traffic analysis tools like Wireshark to inspect RFC protocol compliance. SAP Kernel logs may show memory corruption events. No specific commands are provided in the context.

Impact Analysis

An attacker could exploit this to corrupt memory, potentially leading to unauthorized access, data breaches, or system manipulation. Confidentiality and integrity of data may be compromised, though availability impact is low.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR and HIPAA requirements for data confidentiality and integrity. Organizations may face compliance penalties and reputational damage if exploited.

Mitigation Strategies

Apply the latest SAP Kernel patches from SAP to address the improper RFC protocol validation and memory management issues. Monitor SAP NetWeaver and ABAP Platform systems for unusual memory corruption patterns or unauthorized RFC requests.
