This vulnerability is due to improper handling of certain packets when they are sent to the inspection engine. An attacker could exploit this vulnerability by sending a series of crafted packets to an affected device. A successful exploit could allow the attacker to deplete all 9,472 byte blocks on the device, resulting in traffic loss across the device or an unexpected reload of the device. If the device does not reload on its own, a manual reload of the device would be required to recover from this state."}], "affected": [{"vendor": "Cisco", "product": "Cisco Firepower Threat Defense Software", "versions": [{"version": "6.2.3", "status": "affected"}, {"version": "6.2.3.1", "status": "affected"}, {"version": "6.2.3.2", "status": "affected"}, {"version": "6.2.3.3", "status": "affected"}, {"version": "6.2.3.4", "status": "affected"}, {"version": "6.2.3.5", "status": "affected"}, {"version": "6.2.3.6", "status": "affected"}, {"version": "6.2.3.7", "status": "affected"}, {"version": "6.2.3.8", "status": "affected"}, {"version": "6.2.3.10", "status": "affected"}, {"version": "6.2.3.11", "status": "affected"}, {"version": "6.2.3.9", "status": "affected"}, {"version": "6.2.3.12", "status": "affected"}, {"version": "6.2.3.13", "status": "affected"}, {"version": "6.2.3.14", "status": "affected"}, {"version": "6.2.3.15", "status": "affected"}, {"version": "6.2.3.16", "status": "affected"}, {"version": "6.2.3.17", "status": "affected"}, {"version": "6.2.3.18", "status": "affected"}, {"version": "6.6.0", "status": "affected"}, {"version": "6.6.0.1", "status": "affected"}, {"version": "6.6.1", "status": "affected"}, {"version": "6.6.3", "status": "affected"}, {"version": "6.6.4", "status": "affected"}, {"version": "6.6.5", "status": "affected"}, {"version": "6.6.5.1", "status": "affected"}, {"version": "6.6.5.2", "status": "affected"}, {"version": "6.6.7", "status": "affected"}, {"version": "6.6.7.1", "status": "affected"}, {"version": "6.4.0", "status": "affected"}, {"version": "6.4.0.1", "status": "affected"}, {"version": "6.4.0.3", "status": "affected"}, {"version": "6.4.0.2", "status": "affected"}, {"version": "6.4.0.4", "status": "affected"}, {"version": "6.4.0.5", "status": "affected"}, {"version": "6.4.0.6", "status": "affected"}, {"version": "6.4.0.7", "status": "affected"}, {"version": "6.4.0.8", "status": "affected"}, {"version": "6.4.0.9", "status": "affected"}, {"version": "6.4.0.10", "status": "affected"}, {"version": "6.4.0.11", "status": "affected"}, {"version": "6.4.0.12", "status": "affected"}, {"version": "6.4.0.13", "status": "affected"}, {"version": "6.4.0.14", "status": "affected"}, {"version": "6.4.0.15", "status": "affected"}, {"version": "6.4.0.16", "status": "affected"}, {"version": "6.7.0", "status": "affected"}, {"version": "6.7.0.1", "status": "affected"}, {"version": "6.7.0.2", "status": "affected"}, {"version": "6.7.0.3", "status": "affected"}, {"version": "7.0.0", "status": "affected"}, {"version": "7.0.0.1", "status": "affected"}, {"version": "7.0.1", "status": "affected"}, {"version": "7.0.1.1", "status": "affected"}, {"version": "7.0.2", "status": "affected"}, {"version": "7.0.2.1", "status": "affected"}, {"version": "7.0.3", "status": "affected"}, {"version": "7.0.4", "status": "affected"}, {"version": "7.0.5", "status": "affected"}, {"version": "7.1.0", "status": "affected"}, {"version": "7.1.0.1", "status": "affected"}, {"version": "7.1.0.3", "status": "affected"}, {"version": "7.2.0", "status": "affected"}, {"version": "7.2.0.1", "status": "affected"}, {"version": "7.2.1", "status": "affected"}, {"version": "7.2.2", "status": "affected"}, {"version": "7.2.3", "status": "affected"}, {"version": "7.3.0", "status": "affected"}, {"version": "7.3.1", "status": "affected"}, {"version": "7.3.1.1", "status": "affected"}]}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "Missing Reference to Active Allocated Resource", "type": "cwe", "cweId": "CWE-771"}]}], "references": [{"url": "https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-intrusion-dos-DfT7wyGC", "name": "cisco-sa-ftd-intrusion-dos-DfT7wyGC"}], "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:H", "baseScore": 8.6, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH"}}], "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-ftd-intrusion-dos-DfT7wyGC", "discovery": "INTERNAL", "defects": ["CSCwe98687"]}}, "adp": [{"providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T09:05:36.212Z"}, "title": "CVE Program Container", "references": [{"url": "https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-intrusion-dos-DfT7wyGC", "name": "cisco-sa-ftd-intrusion-dos-DfT7wyGC", "tags": ["x_transferred"]}]}]}}
