SAP NetWeaver AS ABAP (Web Dynpro), versions - 731, 740, 750, 751, 752, 753, 754, 755, 782, allows an authenticated user to access Web Dynpro components, which reveals sensitive system information that would otherwise be restricted to highly privileged users because of missing authorization, resulting in Information Disclosure.

Security readout for executives and security teams

Plain-English summary

CVE-2020-26818 lets a logged-in SAP user view Web Dynpro components that should be limited to highly privileged users. The business risk is sensitive SAP system information disclosure, not system takeover. The issue matters most where broad user populations can authenticate to affected SAP NetWeaver AS ABAP systems.

Executive priority

Prioritize remediation in SAP environments with many users, internet-facing authentication, or sensitive system metadata. This is not a known actively exploited critical issue from the supplied evidence, but it affects confidentiality in business-critical SAP systems.

Technical view

SAP NetWeaver AS ABAP Web Dynpro versions 731, 740, 750, 751, 752, 753, 754, 755, and 782 have missing authorization checks. A low-privileged authenticated network user can access restricted Web Dynpro components and obtain sensitive system information. CVSS 3.0 is 6.5: network, low complexity, low privileges, no user interaction, high confidentiality impact.

Likely exposure

Exposure is likely in organizations running the affected SAP NetWeaver AS ABAP Web Dynpro versions, especially where many business users or partners can authenticate. The vulnerability requires valid credentials, so externally exposed portals are higher concern only when attackers can obtain or reuse accounts.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires authentication but is low complexity once access exists. Treat it as an information-disclosure weakness that could aid reconnaissance or privilege-targeting inside SAP environments.

Researcher notes

No CWE is listed in the supplied record. The CVSS vector supports authenticated, network-reachable, low-complexity information disclosure with no integrity or availability impact. Public evidence supplied here does not include exploit details, proof of concept, or confirmed exploitation.

Mitigation direction

  • Review SAP Note 2971954 and related SAP security guidance.
  • Apply vendor-recommended corrections or support packages for affected systems.
  • Limit Web Dynpro access to users with a clear business need.
  • Review SAP role assignments for unnecessary low-privileged access.
  • Increase monitoring for unusual access to restricted Web Dynpro components.

Validation and detection

  • Inventory SAP NetWeaver AS ABAP systems and Web Dynpro usage.
  • Confirm whether versions 731, 740, 750, 751, 752, 753, 754, 755, or 782 are present.
  • Check whether SAP Note 2971954 corrections are applied.
  • Validate that low-privileged users cannot access restricted Web Dynpro components.
  • Review authentication logs for unexpected low-privileged access patterns.
