This vulnerability is due to the improper handling of large fragmented tunnel protocol packets. One example of a tunnel protocol is Generic Routing Encapsulation (GRE). An attacker could exploit this vulnerability by sending crafted fragmented packets to an affected system. A successful exploit could allow the attacker to cause the affected system to reload, resulting in a DoS condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability."}],"affected":[{"vendor":"Cisco","product":"Cisco IOS XE Software","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"name":"20230322 Cisco IOS XE Software Fragmented Tunnel Protocol Packet Denial of Service Vulnerability","tags":["vendor-advisory"],"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-gre-crash-p6nE5Sq5"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":8.6,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-20","cweId":"CWE-20"}]}],"source":{"advisory":"cisco-sa-ios-gre-crash-p6nE5Sq5","defect":[["CSCwc32921"]],"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":"2024-08-02T08:57:35.870Z"},"title":"CVE Program Container","references":[{"name":"20230322 Cisco IOS XE Software Fragmented Tunnel Protocol Packet Denial of Service Vulnerability","tags":["vendor-advisory","x_transferred"],"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-gre-crash-p6nE5Sq5"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-28T16:24:38.656119Z","id":"CVE-2023-20072","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"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":"2024-10-28T16:32:38.860Z"}}]}}
