CVE-2018-2448
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 SRM-MDM (CATALOG versions 3.0, 7.01, 7.02) utilities functionality allows an attacker to access information of user existence which would otherwise be restricted.
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 confidenceThis is an information disclosure vulnerability in SAP SRM-MDM CATALOG versions 3.0, 7.01, and 7.02. The utilities functionality improperly exposes information about user existence that should be restricted, allowing unauthenticated or low-privileged attackers to enumerate valid usernames through the system.

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.
-
Identify SAP SRM-MDM CATALOG installationCheck your SAP system for installed software components matching 'SRM-MDM CATALOG' using transaction SE16 or SAP LMDB (Landscape Management Database). Query table CVERS or use SAP PAM (Product Availability Matrix) documentation.Affected if The product SAP SRM-MDM CATALOG is installed on the system.
-
Determine installed versionCheck the version of SAP SRM-MDM CATALOG using transaction SAINT (SAP Add-On Installation Tool) or transaction SE16 to query table CVERS_COMPONENTS for component 'SRM-MDM CATALOG'. Compare the installed version against 3.0, 7.01, and 7.02.Affected if The installed version is exactly 3.0, 7.01, or 7.02.
-
Locate utilities functionalityIdentify the URL path or transaction code for the 'utilities' functionality within the SAP SRM-MDM CATALOG module. This is typically accessible via web services or specific SAP transactions related to MDM Catalog administration.Affected if The utilities functionality exists and is accessible within the SRM-MDM CATALOG module.
-
Test for user enumeration exposureSubmit unauthenticated or low-privilege requests to the utilities endpoint and observe whether the response reveals information about valid user accounts (such as existence confirmation, user profile details, or authentication error differences between valid and invalid usernames).Affected if The utilities functionality returns different responses that expose whether specific usernames exist in the system.
A system is affected if SAP SRM-MDM CATALOG versions 3.0, 7.01, or 7.02 is installed and the utilities functionality is exposed, allowing user enumeration through differential responses.

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 dataApply the relevant SAP security patch for CVE-2018-2448. If a patch is unavailable, restrict access to the utilities functionality and review authentication mechanisms to prevent user enumeration.
