This vulnerability is due to improper error handling of an IPv6 packet that is forwarded from an MPLS and ZBFW-enabled interface in a 6VPE deployment. An attacker could exploit this vulnerability by sending a crafted IPv6 packet sourced from a device on the IPv6-enabled virtual routing and forwarding (VRF) interface through the affected device. A successful exploit could allow the attacker to reload the device, resulting in a DoS condition."}],"affected":[{"vendor":"Cisco","product":"Cisco IOS XE Software","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"name":"20220928 Cisco IOS XE Software IPv6 VPN over MPLS Denial of Service Vulnerability","tags":["vendor-advisory"],"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-6vpe-dos-tJBtf5Zv"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":7.4,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-115","cweId":"CWE-115"}]}],"source":{"advisory":"cisco-sa-iosxe-6vpe-dos-tJBtf5Zv","defect":[["CSCwa41184"]],"discovery":"INTERNAL"},"exploits":[{"lang":"en","value":"The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory."}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T02:31:59.767Z"},"title":"CVE Program Container","references":[{"name":"20220928 Cisco IOS XE Software IPv6 VPN over MPLS Denial of Service Vulnerability","tags":["vendor-advisory","x_transferred"],"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-6vpe-dos-tJBtf5Zv"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-11-01T18:40:28.460351Z","id":"CVE-2022-20915","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-11-01T18:49:22.478Z"}}]}}
