This requires attackers to achieve the following before a successful attack can be completed: 1. Have found a vulnerability in the victims spreadsheet software of choice. 2. Control data that would potentially be exported through the `ImportExportController` by a theoretical victim. 3. Convince the victim to export above data as a CSV and run it in vulnerable spreadsheet software while also bypassing any sanity checks by said software. Issue has been patched in Build 466 (v1.0.466)."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-77"}, {"lang": "en", "value": "CWE-77"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2020-5299", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 4.6, "accessVector": "NETWORK", "vectorString": "AV:N/AC:H/Au:S/C:P/I:P/A:P", "authentication": "SINGLE", "integrityImpact": "PARTIAL", "accessComplexity": "HIGH", "availabilityImpact": "PARTIAL", "confidentialityImpact": "PARTIAL"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 6.4, "obtainAllPrivilege": false, "exploitabilityScore": 3.9, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": true}, "baseMetricV3": {"cvssV3": {"scope": "CHANGED", "version": "3.1", "baseScore": 5.1, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:L/A:L", "integrityImpact": "LOW", "userInteraction": "REQUIRED", "attackComplexity": "HIGH", "availabilityImpact": "LOW", "privilegesRequired": "HIGH", "confidentialityImpact": "LOW"}, "impactScore": 3.7, "exploitabilityScore": 1.0}}, "publishedDate": "2020-06-03T22:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:octobercms:october:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "1.0.466", "versionStartIncluding": "1.0.319"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-06-30T14:46Z"}
