The vulnerability exists because broadcast traffic that is received on the 802.1X-enabled port is mishandled. An attacker could exploit this vulnerability by sending broadcast traffic on the port before being authenticated. A successful exploit could allow the attacker to send and receive broadcast traffic on the 802.1X-enabled port before authentication.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2020-3231" }, { "type": "WEB", "url": "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-c2960L-DpWA9Re4" } ], "database_specific": { "cwe_ids": [ "CWE-284", "CWE-863" ], "severity": "MODERATE", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2020-06-03T18:15:00Z" } }
