NOTE: The software maintainer believes that this CVE is not valid. Disabling local password authentication for a user is not the same as disabling all access to that user--the user may still be able to login via other means (ssh key, kerberos, etc). Both the Linux shadow(5) and passwd(1) manuals are clear on this. Indeed it is a valid use case to have local accounts that are _only_ accessible via sudo and that cannot be logged into with a password. Sudo 1.8.30 added an optional setting to check the _shell_ of the target user (not the encrypted password!) against the contents of /etc/shells but that is not the same thing as preventing access to users with an invalid password hash." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "url": "https://www.sudo.ws/stable.html", "refsource": "MISC", "name": "https://www.sudo.ws/stable.html" }, { "refsource": "CONFIRM", "name": "https://www.sudo.ws/devel.html#1.8.30b2", "url": "https://www.sudo.ws/devel.html#1.8.30b2" }, { "refsource": "CONFIRM", "name": "https://security.netapp.com/advisory/ntap-20200103-0004/", "url": "https://security.netapp.com/advisory/ntap-20200103-0004/" }, { "refsource": "MISC", "name": "https://support2.windriver.com/index.php?page=defects&on=view&id=LIN1018-5505", "url": "https://support2.windriver.com/index.php?page=defects&on=view&id=LIN1018-5505" }, { "refsource": "MISC", "name": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58104", "url": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58104" }, { "refsource": "MISC", "name": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58473", "url": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58473" }, { "refsource": "MISC", "name": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58812", "url": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58812" }, { "refsource": "MISC", "name": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58979", "url": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58979" }, { "refsource": "MISC", "name": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58772", "url": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs58772" }, { "refsource": "MISC", "name": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs60748", "url": "https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs60748" }, { "refsource": "MISC", "name": "https://www.tenable.com/plugins/nessus/132985", "url": "https://www.tenable.com/plugins/nessus/132985" }, { "refsource": "MISC", "name": "https://support2.windriver.com/index.php?page=defects&on=view&id=LIN1019-3816", "url": "https://support2.windriver.com/index.php?page=defects&on=view&id=LIN1019-3816" }, { "refsource": "CONFIRM", "name": "https://support2.windriver.com/index.php?page=cve&on=view&id=CVE-2019-19234", "url": "https://support2.windriver.com/index.php?page=cve&on=view&id=CVE-2019-19234" }, { "refsource": "CONFIRM", "name": "https://www.suse.com/security/cve/CVE-2019-19234/", "url": "https://www.suse.com/security/cve/CVE-2019-19234/" }, { "refsource": "MISC", "name": "https://www.bsi.bund.de/SharedDocs/Warnmeldungen/DE/CB/2019/12/warnmeldung_cb-k20-0001.html", "url": "https://www.bsi.bund.de/SharedDocs/Warnmeldungen/DE/CB/2019/12/warnmeldung_cb-k20-0001.html" }, { "refsource": "CONFIRM", "name": "https://access.redhat.com/security/cve/cve-2019-19234", "url": "https://access.redhat.com/security/cve/cve-2019-19234" }, { "refsource": "FEDORA", "name": "FEDORA-2020-8b563bc5f4", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IY6DZ7WMDKU4ZDML6MJLDAPG42B5WVUC/" }, { "refsource": "FEDORA", "name": "FEDORA-2020-7c1b270959", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/I6TKF36KOQUVJNBHSVJFA7BU3CCEYD2F/" }, { "refsource": "CONFIRM", "name": "https://www.oracle.com/security-alerts/bulletinapr2020.html", "url": "https://www.oracle.com/security-alerts/bulletinapr2020.html" } ] } }
