However, if a keytab is not provisioned on the system, pam_krb5 has no way to validate the response from the KDC, and essentially trusts the tgt provided over the network as being valid. In a non-default FreeBSD installation that leverages pam_krb5 for authentication and does not have a keytab provisioned, an attacker that is able to control both the password and the KDC responses can return a valid tgt, allowing authentication to occur for any user on the system.\n"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}]},"weaknesses":[{"source":"secteam@freebsd.org","type":"Secondary","description":[{"lang":"en","value":"CWE-303"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-287"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:*:*:*:*:*:*:*:*","versionEndExcluding":"12.4","matchCriteriaId":"A7F6C8B0-9D75-476C-ADBA-754416FBC186"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:*:*:*:*:*:*:*:*","versionStartIncluding":"13.0","versionEndExcluding":"13.1","matchCriteriaId":"D79AAEBE-0D5A-4C9C-95FD-6287A53EE1C0"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:12.4:-:*:*:*:*:*:*","matchCriteriaId":"24920B4D-96C0-401F-B679-BEB086760EAF"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:12.4:p1:*:*:*:*:*:*","matchCriteriaId":"3CE32730-A9F5-4E8D-BDA4-6B8232F84787"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:12.4:p2:*:*:*:*:*:*","matchCriteriaId":"552E81DE-D409-475F-8ED0-E10A0BE43D29"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:12.4:rc2-p1:*:*:*:*:*:*","matchCriteriaId":"BA821886-B26B-47A6-ABC9-B8F70CE0ACFB"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:12.4:rc2-p2:*:*:*:*:*:*","matchCriteriaId":"220629AD-32CC-4303-86AE-1DD27F0E4C65"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:-:*:*:*:*:*:*","matchCriteriaId":"DEEE6D52-27E4-438D-AE8D-7141320B5973"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:b1-p1:*:*:*:*:*:*","matchCriteriaId":"66364EA4-83B1-4597-8C18-D5633B361A9C"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:b2-p2:*:*:*:*:*:*","matchCriteriaId":"EF9292DD-EFB1-4B50-A941-7485D901489F"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p1:*:*:*:*:*:*","matchCriteriaId":"EFB18F55-4F5C-4166-9A7E-6F6617179A90"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p2:*:*:*:*:*:*","matchCriteriaId":"66E1C269-841F-489A-9A0A-5D145B417E0A"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p3:*:*:*:*:*:*","matchCriteriaId":"ECF1B567-F764-45F5-A793-BEA93720F952"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p4:*:*:*:*:*:*","matchCriteriaId":"DAFE3F33-2C57-4B52-B658-82572607BD8C"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p5:*:*:*:*:*:*","matchCriteriaId":"C925DF75-2785-44BD-91CA-66D29C296689"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p6:*:*:*:*:*:*","matchCriteriaId":"BCE2DAEC-81A5-49E9-B7E7-4F143FA6B3F7"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:p7:*:*:*:*:*:*","matchCriteriaId":"7725D503-1437-4F90-B30C-007193D5F0E1"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.1:rc1-p1:*:*:*:*:*:*","matchCriteriaId":"B536EE52-ED49-4A85-BC9D-A27828D5A961"},{"vulnerable":true,"criteria":"cpe:2.3:o:freebsd:freebsd:13.2:-:*:*:*:*:*:*","matchCriteriaId":"A87EFA20-DD6B-41C5-98FD-A29F67D2E732"}]}]}],"references":[{"url":"https://security.FreeBSD.org/advisories/FreeBSD-SA-23:04.pam_krb5.asc","source":"secteam@freebsd.org","tags":["Mitigation","Vendor Advisory"]},{"url":"https://security.FreeBSD.org/advisories/FreeBSD-SA-23:09.pam_krb5.asc","source":"secteam@freebsd.org"},{"url":"https://security.netapp.com/advisory/ntap-20230714-0005/","source":"secteam@freebsd.org","tags":["Third Party Advisory"]},{"url":"https://security.FreeBSD.org/advisories/FreeBSD-SA-23:04.pam_krb5.asc","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mitigation","Vendor Advisory"]},{"url":"https://security.FreeBSD.org/advisories/FreeBSD-SA-23:09.pam_krb5.asc","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://security.netapp.com/advisory/ntap-20230714-0005/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]}]}}]}
