The vulnerability is due to a logic error in the affected software. An attacker could exploit this vulnerability by connecting to and passing traffic through a Layer 3 interface of an affected device, if the interface is configured for MACsec MKA using EAP-TLS and is running in access-session closed mode. A successful exploit could allow the attacker to bypass 802.1x network access controls and gain access to the network.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2018-15372" }, { "type": "WEB", "url": "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-macsec" }, { "type": "WEB", "url": "http://www.securityfocus.com/bid/105416" } ], "database_specific": { "cwe_ids": [], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2018-10-05T14:29:00Z" } }
