CVE-2018-2403
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnder certain conditions, SAP Disclosure Management 10.1 allows an attacker to access information which would otherwise be restricted. It is possible for an authorized user to get SAP Disclosure Management to point a specific chapter type to a chapter the user has not been given access to.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSAP Disclosure Management 10.1 contains an Insecure Direct Object Reference (IDOR) vulnerability where an authorized user can manipulate chapter type references to access chapters they have not been granted permission to view. This is a broken access control issue where the application fails to properly validate user authorization when accessing specific chapter objects.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm SAP Disclosure Management versionLocate the installed version of SAP Disclosure Management in the application about screen, installation directory, or system information. This is typically found in the program metadata or Help > About section.Affected if The installed version is exactly 10.1 (no patches applied)
-
Verify chapter functionality is in useDetermine if the application is using the chapter management feature where users can create, access, or manage document chapters or sections.Affected if The chapter feature is enabled and users have access to create or view chapters
-
Test for IDOR in chapter accessAs an authorized user with limited chapter permissions, attempt to access a chapter by directly manipulating the chapter reference identifier in the request (such as the chapter ID parameter) to access a chapter you have not been granted permission to view.Affected if You are able to view or access chapters you were not explicitly granted permission to access by modifying the chapter reference in the request
-
Review authorization validation in application logsExamine application and server logs for access patterns where chapter requests succeed despite the requesting user lacking documented permission for that specific chapter object.Affected if Logs show successful chapter access by users without explicit permission to that specific chapter
-
Check for server-side authorization enforcementInspect the application configuration or consult SAP documentation to verify whether server-side authorization validation is properly enforced for chapter access controls.Affected if Server-side authorization validation is missing or improperly configured for chapter object access
A user is affected if they are running SAP Disclosure Management version 10.1 and the application allows users to access chapters they have not been explicitly granted permission to view by manipulating chapter references in requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper server-side authorization validation to ensure users can only access chapters they have explicit permission to view, regardless of how the chapter reference is submitted.
