This vulnerability is due to a memory handling error that occurs when GRE traffic is processed. An attacker could exploit this vulnerability by sending a crafted GRE payload through an affected device. A successful exploit could allow the attacker to cause the device to restart, resulting in a DoS condition. https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-gre-dos-hmedHQPM [\"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-gre-dos-hmedHQPM\"] This advisory is part of the November 2022 release of the Cisco ASA, FTD, and FMC Security Advisory Bundled publication." } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH" }, "exploitabilityScore": 3.9, "impactScore": 3.6 }, { "source": "ykramarz@cisco.com", "type": "Secondary", "cvssData": { "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" }, "exploitabilityScore": 3.9, "impactScore": 4.0 } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-787" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3.0", "versionEndIncluding": "6.3.0.5", "matchCriteriaId": "EDE0C110-518D-4E51-BCEB-F4E9FC448278" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4.0", "versionEndIncluding": "6.4.0.15", "matchCriteriaId": "874E0E13-4A9E-4296-BEE6-F5B1077411A0" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.5.0", "versionEndIncluding": "6.5.0.5", "matchCriteriaId": "171E1C5D-68C5-4BBC-AE18-D1518A1B7277" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6.0", "versionEndIncluding": "6.6.5.2", "matchCriteriaId": "6362D78F-F131-46E4-8F0E-C7F218500017" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.7.0", "versionEndIncluding": "6.7.0.3", "matchCriteriaId": "1110632C-526F-4025-A7BE-0CF9F37E5F9E" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "versionStartIncluding": "7.0.0", "versionEndIncluding": "7.0.3", "matchCriteriaId": "89DFD86B-768D-4301-92DB-B73C14255123" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:7.1.0.0:*:*:*:*:*:*:*", "matchCriteriaId": "B7533780-0DF9-41BE-8455-F60676785689" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:7.1.0.1:*:*:*:*:*:*:*", "matchCriteriaId": "469EA365-DED5-4436-AAC2-5553529DE700" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:firepower_threat_defense:7.1.0.2:*:*:*:*:*:*:*", "matchCriteriaId": "4D94F400-5A35-41F5-B37F-E9DA6F87ED8E" } ] } ] } ], "references": [ { "url": "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-gre-dos-hmedHQPM", "source": "ykramarz@cisco.com", "tags": [ "Patch", "Vendor Advisory" ] } ] }
