The vulnerability is due to insufficient validation of SSL/TLS messages when the device performs software-based SSL decryption. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. A successful exploit could allow the attacker to cause a process to crash. This crash would then trigger a reload of the device. No manual intervention is needed to recover the device after the reload."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-20"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2021-1402", "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": "CHANGED", "version": "3.1", "baseScore": 8.6, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 4.0, "exploitabilityScore": 3.9}}, "publishedDate": "2021-04-29T18:15Z", "configurations": {"nodes": [{"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.6.0", "versionStartIncluding": "6.5.0"}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.4.0", "versionStartIncluding": "6.3.0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:cisco:asa_5512-x:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:asa_5515-x:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:asa_5525-x:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:asa_5545-x:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:asa_5555-x:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_2110:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_2120:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_2130:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_2140:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:a:cisco:firepower_threat_defense_virtual:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_1010:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_1120:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_1140:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:isa_3000:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:firepower_1150:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-08-05T16:17Z"}
