When a trust relationship is configured between FreeIPA and Active Directory, Active Directory users can bypass authentication for FreeIPA services, including the portal, SMB server, and LDAP directory. This is possible by impersonating a client name in the Ticket Granting Service (TGS) due to FreeIPA services not verifying Privilege Attribute Certificate (PAC) certificates. This vulnerability could allow an authenticated Active Directory user to escalate their privileges within the FreeIPA domain.", "affected": [ { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 10", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:4.13.4-1.el10_2", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 10.0 Extended Update Support", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:4.12.2-15.el10_0.7", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8", "packageName": "idm:client", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "8100020261007071200.143e9e98", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8", "packageName": "idm:DL1", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "8100020261007070536.823393f5", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.8 Telecommunications Update Service", "packageName": "idm:client", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "8080020261007080925.e581a9e4", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.8 Telecommunications Update Service", "packageName": "idm:DL1", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "8080020261007071832.b0a6ceea", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions", "packageName": "idm:client", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "8080020261007080925.e581a9e4", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions", "packageName": "idm:DL1", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "8080020261007071832.b0a6ceea", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:4.13.4-1.el9_8", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:4.10.1-12.el9_2.7", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:4.11.0-15.el9_4.9", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.6 Extended Update Support", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:4.12.2-14.el9_6.8", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 6", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "unknown", "versions": [] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 7", "packageName": "ipa", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [] } ] } } }
