Under normal circumstances, this access should be prohibited. The vulnerability is due to the dynamic assignment of Security Group Tags (SGTs) during a wireless roam from one Service Set Identifier (SSID) to another within the Cisco TrustSec domain. An attacker could exploit this vulnerability by attempting to acquire an SGT from other SSIDs within the domain. Successful exploitation could allow the attacker to gain privileged network access that should be prohibited under normal circumstances.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-284"],"references":["http://www.securityfocus.com/bid/105676","http://www.securitytracker.com/id/1041925","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181017-wlan-escalation","http://www.securityfocus.com/bid/105676","http://www.securitytracker.com/id/1041925"],"products":["cisco:wireless_lan_controller_software"],"source":"nvd","synced_at":"2026-10-19T20:53:59.789560037+00:00"},"epss":{"cve":"CVE-2018-15395","score":0.00583,"percentile":0.47873,"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).
