The web interface could allow Cross-Site Scripting (XSS) attacks if an attacker is able to modify content of particular web pages, causing the application to behave in unexpected ways for legitimate users. Successful exploitation does not require for an attacker to be authenticated to the web interface. This could allow the attacker to read or modify contents of the web application. At the time of advisory publication no public exploitation of this security. vulnerability was known.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://cert-portal.siemens.com/productcert/pdf/ssa-418979.pdf","https://www.us-cert.gov/ics/advisories/icsa-19-344-07","https://cert-portal.siemens.com/productcert/pdf/ssa-418979.pdf","https://www.us-cert.gov/ics/advisories/icsa-19-344-07"],"products":["siemens:en100_ethernet_module_with_firmware_variant_dnp3_tcp","siemens:en100_ethernet_module_with_firmware_variant_iec104","siemens:en100_ethernet_module_with_firmware_variant_iec_61850","siemens:en100_ethernet_module_with_firmware_variant_modbus_tcp","siemens:en100_ethernet_module_with_firmware_variant_profinet_io"],"source":"nvd","synced_at":"2026-10-19T20:59:27.069234358+00:00"},"epss":{"cve":"CVE-2019-13943","score":0.00887,"percentile":0.59313,"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).
