An attacker could exploit this vulnerability by sending specific Ethernet frames through an affected device. A successful exploit could allow the attacker to cause the ingress interface network processor to reset, resulting in a loss of traffic over the interfaces that are supported by the network processor. Multiple resets of the network processor would cause the line card to reset, resulting in a DoS condition."}],"affected":[{"vendor":"Cisco","product":"Cisco IOS XR Software","versions":[{"version":"6.5.2","status":"affected"},{"version":"6.5.3","status":"affected"},{"version":"6.6.2","status":"affected"},{"version":"6.6.3","status":"affected"},{"version":"6.6.25","status":"affected"},{"version":"7.0.1","status":"affected"},{"version":"7.0.2","status":"affected"},{"version":"7.1.1","status":"affected"},{"version":"7.1.15","status":"affected"},{"version":"7.1.2","status":"affected"},{"version":"7.1.3","status":"affected"},{"version":"6.7.1","status":"affected"},{"version":"6.7.2","status":"affected"},{"version":"6.7.3","status":"affected"},{"version":"7.3.1","status":"affected"},{"version":"7.3.2","status":"affected"},{"version":"7.3.3","status":"affected"},{"version":"7.3.5","status":"affected"},{"version":"7.4.1","status":"affected"},{"version":"7.4.2","status":"affected"},{"version":"6.8.1","status":"affected"},{"version":"6.8.2","status":"affected"},{"version":"7.5.1","status":"affected"},{"version":"7.5.3","status":"affected"},{"version":"7.5.2","status":"affected"},{"version":"7.5.4","status":"affected"},{"version":"7.5.5","status":"affected"},{"version":"7.6.1","status":"affected"},{"version":"7.6.2","status":"affected"},{"version":"7.7.1","status":"affected"},{"version":"7.7.2","status":"affected"},{"version":"6.9.1","status":"affected"},{"version":"6.9.2","status":"affected"},{"version":"7.8.1","status":"affected"},{"version":"7.8.2","status":"affected"},{"version":"7.9.1","status":"affected"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Improper Input Validation","type":"cwe","cweId":"CWE-20"}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xrl2vpn-jesrU3fc","name":"cisco-sa-xrl2vpn-jesrU3fc"}],"metrics":[{"format":"cvssV3_1","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","baseScore":7.4,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"}}],"exploits":[{"lang":"en","value":"The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory."}],"source":{"advisory":"cisco-sa-xrl2vpn-jesrU3fc","discovery":"EXTERNAL","defects":["CSCwe29150"]}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-20318","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-03-13T18:14:49.794916Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-07-05T17:22:18.112Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-01T21:59:41.382Z"},"title":"CVE Program Container","references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xrl2vpn-jesrU3fc","name":"cisco-sa-xrl2vpn-jesrU3fc","tags":["x_transferred"]}]}]}}
