An attacker could exploit this vulnerability by sending a stream of crafted SIP traffic through an interface on the targeted device. A successful exploit could allow the attacker to trigger a restart of the Snort 3 process, resulting in a denial of service (DoS) condition."}],"affected":[{"vendor":"Cisco","product":"Cisco Firepower Threat Defense Software","versions":[{"version":"7.2.0","status":"affected"},{"version":"7.2.0.1","status":"affected"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Allocation of Resources Without Limits or Throttling","type":"cwe","cweId":"CWE-770"}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftdsnort3sip-dos-A4cHeArC","name":"cisco-sa-ftdsnort3sip-dos-A4cHeArC"}],"metrics":[{"format":"cvssV3_1","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","baseScore":5.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"}}],"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."}],"source":{"advisory":"cisco-sa-ftdsnort3sip-dos-A4cHeArC","discovery":"EXTERNAL","defects":["CSCwb99509"]}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T02:31:58.477Z"},"title":"CVE Program Container","references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftdsnort3sip-dos-A4cHeArC","name":"cisco-sa-ftdsnort3sip-dos-A4cHeArC","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-01-29T21:08:12.183436Z","id":"CVE-2022-20950","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":"2024-11-19T21:05:42.392Z"}}]}}
