Under Active Attack

Executive Summary

SAP released critical security updates in September 2026 addressing multiple vulnerabilities, including CVE-2026-44756, a maximum-severity CVSS 10.0 flaw in SAP Extended Passport Processing. Discovered by Onapsis and codenamed OVERPASS, this memory corruption vulnerability allows unauthenticated remote attackers to execute arbitrary operating system commands with SAP administrative privileges. The flaw affects SAP kernel code across multiple protocols including web, GUI, and RFC layers, making it reachable through internet-facing components without requiring credentials. Successful exploitation enables complete compromise of SAP business data, lateral movement to connected systems, and manipulation of critical application configurations.

This incident highlights the growing threat landscape targeting enterprise resource planning systems as organizations increasingly digitize their core business processes. With SAP systems managing critical financial and operational data for thousands of enterprises globally, kernel-level vulnerabilities represent existential risks that bypass traditional authentication controls and demand immediate remediation efforts.

Why This Matters Now

Enterprise ERP systems face unprecedented attack sophistication targeting kernel-level vulnerabilities that bypass authentication entirely, requiring organizations to prioritize critical patch management and implement defense-in-depth strategies for business-critical applications managing sensitive financial and operational data.

Frequently Asked Questions

This CVSS 10.0 vulnerability allows unauthenticated remote attackers to execute operating system commands with SAP administrative privileges, bypassing all authentication controls and enabling complete system compromise.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Based on the attack progression modeled above, these are the defensive controls that would constrain each stage.

Aviatrix Zero Trust CNSF would likely constrain this SAP attack by segmenting network access and reducing lateral movement capabilities across the SAP landscape. The blast radius of credential extraction and system compromise could be significantly limited through workload isolation and east-west traffic enforcement.

Initial Compromise

Control: Cloud Native Security Fabric (CNSF)

Mitigation: Network segmentation policies could limit which systems can reach vulnerable SAP servers, potentially reducing the attack surface exposed to external threats attempting to exploit the EPP vulnerability

Privilege Escalation

Control: Zero Trust Segmentation

Mitigation: Workload isolation policies would likely limit the scope of administrative access across SAP cluster nodes, constraining an attacker's ability to leverage elevated privileges across multiple connected systems simultaneously

Lateral Movement

Control: East-West Traffic Security

Mitigation: Traffic inspection and segmentation policies would likely constrain lateral movement between SAP systems, limiting an attacker's ability to traverse the entire SAP landscape using extracted credentials

Command & Control

Control: Multicloud Visibility & Control

Mitigation: Network visibility and traffic analysis capabilities would likely detect anomalous communication patterns across SAP protocol layers, potentially constraining persistent command channel establishment

Exfiltration

Control: Egress Security & Policy Enforcement

Mitigation: Controlled egress policies would likely limit large-scale data extraction by constraining outbound connectivity and monitoring unusual data transfer volumes from compromised SAP systems

Impact (Mitigations)

Residual impact would likely be contained to isolated SAP system segments rather than affecting the entire landscape, reducing business process disruption scope and limiting data integrity compromise exposure

Data Exposure

Potential exposure of SAP secure store contents including database credentials, password hashes, business data, live session data of logged-in users, and stored credentials for lateral movement across SAP systems. Complete compromise of underlying SAP business data and processes possible.

Recommended Actions

  • • Implement inline IPS with Suricata signatures to detect and block exploit attempts targeting CVE-2026-44756 and similar kernel vulnerabilities before they reach SAP systems
  • • Deploy Zero Trust segmentation with identity-based policies to contain lateral movement between SAP systems and prevent credential-based pivoting across the environment
  • • Enable multicloud visibility and control to monitor anomalous interactions and detect repeated malformed requests targeting SAP Extended Passport Processing endpoints
  • • Establish egress security and policy enforcement to prevent exfiltration of SAP business data and detect unauthorized outbound connections from compromised systems
  • • Implement east-west traffic security controls to monitor and restrict workload-to-workload communications between SAP application servers and connected systems
