An attacker with network access to the device could send specially crafted network packets to determine whether or not a network port on another remote system is accessible or not. This allows the attacker to do basic network scanning using the victims machine. Successful exploitation requires a network connection to the affected device. The attacker does not need privileges, no user interaction is required. The impact is limited to determining whether or not a port on a target system is accessible by the affected device.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":5.8},"cwes":["CWE-284"],"references":["http://www.securityfocus.com/bid/105114","https://cert-portal.siemens.com/productcert/pdf/ssa-920962.pdf","http://www.securityfocus.com/bid/105114","https://cert-portal.siemens.com/productcert/pdf/ssa-920962.pdf"],"products":["siemens:automation_license_manager"],"source":"nvd","synced_at":"2026-10-19T20:52:03.425131697+00:00"},"epss":{"cve":"CVE-2018-11456","score":0.01257,"percentile":0.69561,"date":"2026-10-31"},"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).
