CVE-2018-2449
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 · uneditedSAP SRM MDM Catalog versions 3.73, 7.31, 7.32 in (SAP NetWeaver 7.3) - import functionality does not perform authentication checks for valid repository user. This is an unauthenticated functionality that you can use on windows machines to do SMB relaying.
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 · high confidenceSAP SRM MDM Catalog import functionality lacks authentication validation, allowing unauthenticated attackers to access the import mechanism. On Windows systems, this can be exploited for SMB relaying attacks since the vulnerable component handles SMB connections without verifying the requesting user's credentials.

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 if SAP Supplier Relationship Management MDM Catalog component is installed on the system by reviewing installed SAP software packages or checking for MDM Catalog executables/services in the SAP system directory (typically under /usr/sap or the SAP installation root)Affected if The SAP SRM MDM Catalog component is present on the system
-
Verify installed versionLocate the MDM Catalog version information in the SAP system: check the SAP System Landscape Directory (SLD), transaction code SPAM for SAP SRM component versions, or examine the MDM Catalog binary/executable version propertiesAffected if The installed version matches 3.73, 7.31, or 7.32 exactly (exact version match required)
-
Confirm MDM Catalog import functionality is enabledCheck if the MDM Catalog import service is running and accessible. This typically involves verifying the MDM Catalog HTTP/HTTPS endpoint is exposed and the import module is loaded in the SAP system configuration (check via transaction SM37 for MDM-related jobs or RFC destinations)Affected if The import functionality is active and the service is listening for import requests
-
Check Windows platform for SMB exposureDetermine the operating system hosting the SAP application. On Windows systems, verify if SMB ports (445/tcp, 139/tcp) are open and accessible from the network, as the vulnerability allows SMB relaying attacks on Windows hostsAffected if The SAP system runs on Windows and has exposed SMB ports (445 or 139)
-
Assess network accessibility of import serviceReview network configuration to determine if the MDM Catalog import endpoint is reachable from untrusted networks. Check firewall rules and SAP ICM/Internet Communication Manager configuration for exposed ports related to MDM functionalityAffected if The import functionality is exposed to network segments beyond trusted internal networks
The environment is affected if SAP SRM MDM Catalog versions 3.73, 7.31, or 7.32 are installed with the import functionality enabled and accessible, particularly on Windows systems with exposed SMB ports.

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 appropriate SAP security patches/notes for CVE-2018-2449. If patches are unavailable, implement network segmentation to restrict SMB access and disable the import functionality until a fix is available.
