The intended (and documented) behavior is that if an operator has not specified a value for the \"allow-recursion\" setting, it SHOULD default to one of the following: none, if \"recursion no;\" is set in named.conf; a value inherited from the \"allow-query-cache\" or \"allow-query\" settings IF \"recursion yes;\" (the default for that setting) AND match lists are explicitly set for \"allow-query-cache\" or \"allow-query\" (see the BIND9 Administrative Reference Manual section 6.2 for more details); or the intended default of \"allow-recursion {localhost; localnets;};\" if \"recursion yes;\" is in effect and no values are explicitly set for \"allow-query-cache\" or \"allow-query\". However, because of the regression introduced by change #4777, it is possible when \"recursion yes;\" is in effect and no match list values are provided for \"allow-query-cache\" or \"allow-query\" for the setting of \"allow-recursion\" to inherit a setting of all hosts from the \"allow-query\" setting default, improperly permitting recursion to all clients. Affects BIND 9.9.12, 9.10.7, 9.11.3, 9.12.0->9.12.1-P2, the development release 9.13.0, and also releases 9.9.12-S1, 9.10.7-S1, 9.11.3-S1, and 9.11.3-S2 from BIND 9 Supported Preview Edition."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-200"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2018-5738", "ASSIGNER": "security-officer@isc.org"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 5.0, "accessVector": "NETWORK", "vectorString": "AV:N/AC:L/Au:N/C:P/I:N/A:N", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "LOW", "availabilityImpact": "NONE", "confidentialityImpact": "PARTIAL"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 10.0, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.0", "baseScore": 7.5, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH"}, "impactScore": 3.6, "exploitabilityScore": 3.9}}, "publishedDate": "2019-01-16T20:29Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:isc:bind:9.10.7:s1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.10.7:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.0:rc3:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.1:p1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.0:a1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.0:b1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.0:b2:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.0:rc1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.11.3:s2:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.11.3:s1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.1:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.9.12:s1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.11.3:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.12.1:p2:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.13.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:isc:bind:9.9.12:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*", "cpe_name": [], "vulnerable": true}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2019-08-30T17:15Z"}
