CVE-2026-76963 in ABAP Platform
Summary
by MITRE • 09/08/2026
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. Successful exploitation could result in exposure of security relevant settings and internal system details, resulting in low impact on confidentiality while integrity and availability remain unaffected.

The vulnerability identified involves a critical missing authorization check within the Application Server ABAP component of SAP NetWeaver and the ABAP Platform. This architectural flaw allows an authenticated attacker to bypass intended security controls and access sensitive system configuration information that should be restricted to privileged administrators or specific authorized roles. The core technical issue lies in the failure of the application logic to verify user permissions before processing requests for internal system data, effectively creating a path for unauthorized information disclosure despite the presence of basic authentication mechanisms.
From an operational perspective, this flaw results in the exposure of security-relevant settings and detailed internal system architecture details. While the impact on confidentiality is classified as low because the exposed data typically consists of configuration parameters rather than direct credentials or customer personal data, it provides attackers with valuable intelligence for further reconnaissance. Knowledge of these internal configurations can facilitate more sophisticated attacks by revealing potential weak points in network segmentation, service endpoints, or integration interfaces that could be targeted in subsequent exploitation attempts.
The integrity and availability aspects of the system remain unaffected by this specific vulnerability, as the attacker cannot modify existing data nor disrupt services through this vector alone. However, the disclosure of internal details contributes to a broader risk profile by reducing the security posture's opacity, making it easier for adversaries to map out the environment and plan more targeted intrusion activities that could eventually impact integrity or availability if other vulnerabilities are present in conjunction with this information leak.
This vulnerability aligns with CWE-284, which describes Improper Access Control, specifically highlighting scenarios where access control decisions are not properly enforced before granting access to resources. In terms of the MITRE ATT&CK framework, this behavior corresponds to techniques under the Discovery tactic, particularly those related to System Information Discovery or Application Window Discovery, as attackers leverage exposed configuration data to understand the target environment's structure and capabilities for future exploitation phases.
Mitigation strategies should focus on implementing strict role-based access control checks at every entry point where sensitive system information is accessed. Developers must ensure that all API endpoints and internal services perform comprehensive authorization validation against user roles before returning any configuration details. Additionally, security teams should review existing ABAP codebases to identify similar patterns of missing authorization logic across other modules. Regular penetration testing focused on access control bypasses and continuous monitoring for unusual queries targeting system configuration tables can help detect attempts to exploit this flaw in real-time while patches are being applied or workarounds are implemented.
