These are now going to be discarded in Mahara along with NULL characters and invalid Unicode characters. Mahara will also avoid direct $_GET and $_POST usage where possible, and instead use param_exists() and the correct param_*() function to fetch the expected value."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-79"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2017-17454", "ASSIGNER": "cve@mitre.org"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 3.5, "accessVector": "NETWORK", "vectorString": "AV:N/AC:M/Au:S/C:N/I:P/A:N", "authentication": "SINGLE", "integrityImpact": "PARTIAL", "accessComplexity": "MEDIUM", "availabilityImpact": "NONE", "confidentialityImpact": "NONE"}, "severity": "LOW", "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 6.8, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": true}, "baseMetricV3": {"cvssV3": {"scope": "CHANGED", "version": "3.0", "baseScore": 5.4, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N", "integrityImpact": "LOW", "userInteraction": "REQUIRED", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "LOW", "confidentialityImpact": "LOW"}, "impactScore": 2.7, "exploitabilityScore": 2.3}}, "publishedDate": "2018-02-20T22:29Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:mahara:mahara:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "16.10.7", "versionStartIncluding": "16.10.0"}, {"cpe23Uri": "cpe:2.3:a:mahara:mahara:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "17.04.5", "versionStartIncluding": "17.04.0"}, {"cpe23Uri": "cpe:2.3:a:mahara:mahara:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "17.10.2", "versionStartIncluding": "17.10.0"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2018-03-16T14:37Z"}
