The vulnerability is due to a watchdog timeout and crash during the cleanup of threads that are associated with a SIP connection that is being deleted from the connection list. An attacker could exploit this vulnerability by sending a high rate of crafted SIP traffic through an affected device. A successful exploit could allow the attacker to cause a watchdog timeout and crash, resulting in a crash and reload of the affected device."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-404"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2020-3555", "ASSIGNER": "psirt@cisco.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 7.8, "accessVector": "NETWORK", "vectorString": "AV:N/AC:L/Au:N/C:N/I:N/A:C", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "LOW", "availabilityImpact": "COMPLETE", "confidentialityImpact": "NONE"}, "severity": "HIGH", "acInsufInfo": false, "impactScore": 6.9, "obtainAllPrivilege": false, "exploitabilityScore": 10.0, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.5, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 3.9}}, "publishedDate": "2020-10-21T19:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.6.4.43"}, {"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.8.4.24", "versionStartIncluding": "9.7.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.9.2.80", "versionStartIncluding": "9.9.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.10.1.43", "versionStartIncluding": "9.10.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.12.4.2", "versionStartIncluding": "9.12.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.13.1.13", "versionStartIncluding": "9.13.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:adaptive_security_appliance:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.14.1.19", "versionStartIncluding": "9.14.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "6.2.2"}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.3.0.6", "versionStartIncluding": "6.3.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.4.0.10", "versionStartIncluding": "6.4.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.5.0.5", "versionStartIncluding": "6.5.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:6.6.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2020-10-27T15:19Z"}
