An attacker in a machine-in-the-middle position could exploit this vulnerability by sending crafted UDP packets to an affected device. A successful exploit could allow the attacker to cause the device to reboot, resulting in a DoS condition on the affected system." } ], "metrics": { "cvssMetricV31": [ { "source": "ykramarz@cisco.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H", "attackVector": "ADJACENT_NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "baseScore": 6.1, "baseSeverity": "MEDIUM" }, "exploitabilityScore": 1.6, "impactScore": 4.0 } ] }, "weaknesses": [ { "source": "ykramarz@cisco.com", "type": "Secondary", "description": [ { "lang": "en", "value": "CWE-787" } ] } ], "references": [ { "url": "https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdw-vedos-KqFfhps3", "source": "ykramarz@cisco.com" } ] }
