When parsing the XMLNS value of an ArchiMate project file, if the namespace does not match the expected ArchiMate URL, the parser will access the provided resource. If the provided resource is a UNC path pointing to a share server that does not accept a guest account, the host will try to authenticate on the share by using the current user's session. NOTE: this issue occurs because Archi uses an unsafe configuration of the Eclipse Modeling Framework.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","score":6.5},"cwes":[],"references":["https://github.com/archimatetool/archi/commit/bcab676beddfbeddffecacf755b6692f0b0151f1","https://github.com/archimatetool/archi/compare/release_5.0.2...release_5.1.0","https://github.com/archimatetool/archi/issues/946","https://github.com/eclipse-emf/org.eclipse.emf/issues/8","https://github.com/archimatetool/archi/commit/bcab676beddfbeddffecacf755b6692f0b0151f1"],"products":["opengroup:archi"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-40235","score":0.00842,"percentile":0.57928,"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).
