When no adequate protection has been enforced on any level (e.g., MDS Server password not set, network and OS configuration not properly secured, etc.), a malicious user might define UNC paths which could then be exploited to put the system at risk using a so-called SMB relay attack and obtain highly sensitive data, which leads to Information Disclosure.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://launchpad.support.sap.com/#/notes/2993032","https://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=564760476","https://launchpad.support.sap.com/#/notes/2993032","https://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=564760476"],"products":["sap:netweaver_master_data_management"],"source":"nvd","synced_at":"2026-10-19T21:12:09.559580076+00:00"},"epss":{"cve":"CVE-2021-21469","score":0.01204,"percentile":0.68265,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
