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.","severity":{"version":"3.0","score":5.8,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-08","score":0.01257,"percentile":0.69744,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-284"],"published":"2018-08-07T15:00:00Z","modified":"2026-06-17T01:35:58Z","products":[{"vendor":"siemens","product":"automation license manager 5"},{"vendor":"siemens","product":"automation_license_manager"},{"vendor":"siemens ag","product":"automation license manager 5"}],"references":[{"url":"http://www.securityfocus.com/bid/105114","tags":["vdb-entry","x_refsource_BID","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://cert-portal.siemens.com/productcert/pdf/ssa-920962.pdf","tags":["x_refsource_CONFIRM","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-11456"},{"url":"https://github.com/advisories/GHSA-qwxx-q8h8-xx3q"}],"sources":{"cve":[{"id":"CVE-2018-11456","description":"A vulnerability has been identified in Automation License Manager 5 (All versions \u003c 5.3.4.4).
