{"cve": {"data_type": "CVE", "references": {"reference_data": [{"url": "https://security.paloaltonetworks.com/CVE-2021-3031", "name": "N/A", "tags": ["Vendor Advisory"], "refsource": "CONFIRM"}]}, "data_format": "MITRE", "description": {"description_data": [{"lang": "en", "value": "Padding bytes in Ethernet packets on PA-200, PA-220, PA-500, PA-800, PA-2000 Series, PA-3000 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series firewalls are not cleared before the data frame is created. This leaks a small amount of random information from the firewall memory into the Ethernet packets. An attacker on the same Ethernet subnet as the PAN-OS firewall is able to collect potentially sensitive information from these packets. This issue is also known as Etherleak and is detected by security scanners as CVE-2003-0001. This issue impacts: PAN-OS 8.1 version earlier than PAN-OS 8.1.18; PAN-OS 9.0 versions earlier than PAN-OS 9.0.12; PAN-OS 9.1 versions earlier than PAN-OS 9.1.5."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-212"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2021-3031", "ASSIGNER": "psirt@paloaltonetworks.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 3.3, "accessVector": "ADJACENT_NETWORK", "vectorString": "AV:A/AC:L/Au:N/C:P/I:N/A:N", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "LOW", "availabilityImpact": "NONE", "confidentialityImpact": "PARTIAL"}, "severity": "LOW", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 6.5, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 4.3, "attackVector": "ADJACENT_NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "NONE", "confidentialityImpact": "LOW"}, "impactScore": 1.4, "exploitabilityScore": 2.8}}, "publishedDate": "2021-01-13T18:15Z", "configurations": {"nodes": [{"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:paloaltonetworks:pan-os:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.1.5", "versionStartIncluding": "9.1.0"}, {"cpe23Uri": "cpe:2.3:o:paloaltonetworks:pan-os:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "9.0.12", "versionStartIncluding": "9.0.0"}, {"cpe23Uri": "cpe:2.3:o:paloaltonetworks:pan-os:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "8.1.18", "versionStartIncluding": "8.1.0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-3060:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-3050:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-3020:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-3260:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-3250:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-3220:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-5200:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-220:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-2050:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-2020:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-500:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-800:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:paloaltonetworks:pa-200:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-10-27T12:51Z"}
