![]() ![]() ![]() Only the specified command can be run, this flaw does NOT allow user to run other commands that those specified in the sudoers configuration.Īny other configurations of sudo (including configurations that allow user to run commands as any user including root and configurations that allow user to run command as a specific other user) are NOT affected by this flaw."Īs I see it, if I give user ‘bob’ sudo permissions for everything except for vi (the bob myhost =(ALL, !root) /usr/bin/vi ) then the user bob could run vi as Sudo with this hack.Ĭan’t see it being an issue in Hass.io or in hassbian. However, this flaw also allows bob to run the vi command as root by specifying the target user using the numeric id of -1. ![]() This configuration allows user bob to run vi command as any other user except root. These can be found in the /etc/sudoers file or files under /etc/sudoers.d."This flaw only affects specific, non-default configurations of sudo, in which sudoers configuration entry allows a user to run a command as any user except root, for example: To ensure your sudoers configuration is not affected by this vulnerability, we recommend examining each sudoers entry that includes the ! character in the runas specification, to ensure that the root user is not among the exclusions. Someuser ALL=(ALL, !MYGROUP) /usr/bin/somecommand Or by reference to a runas alias: Runas_Alias MYGROUP = root, adminuser The root user may also be identified in other ways, such as by user id: someuser ALL=(ALL, !#0) /usr/bin/somecommand someuser ALL=(ALL, !root) /usr/bin/somecommand In this example, the "root" user is specified by name. The exclusion is specified using an excalamation mark (!). Only the specified command can be run, this flaw does NOT allow user to run other commands that those specified in the sudoers configuration.Īny other configurations of sudo (including configurations that allow user to run commands as any user including root and configurations that allow user to run command as a specific other user) are NOT affected by this flaw. This flaw only affects configurations of sudo, in which sudoers configuration entry allows a user to run a command as any user except root, for example: bob myhost = (ALL, !root) /usr/bin/vi If a sudoers entry is written to allow the attacker to run a command as any user except root, this flaw can be used by the attacker to bypass that restriction. Please see the diagnosis step for more information.Ī flaw was found in the way sudo implemented running commands with arbitrary user ID. If no fix is available for the version of software you are running, please review your sudoers configuration to ensure they are not affected by this vulnerability.Red Hat OpenShift Container Platform 4.2 - Not released yet Red Hat OpenShift Container Platform 4.1 - Not released yet Red Hat Virtualization 4 - RHBA-2019:3248 Red Hat Enterprise Linux 5 - Out of support scope ![]() Red Hat Enterprise Linux 6.6 Advanced Update Support - Fixed with sudo-1.8.6p3-15 via RHSA-2019:3754 Red Hat Enterprise Linux 6 - Fixed with sudo-1.8.6p3-29 via RHSA-2019:3755 Red Hat Enterprise Linux 7.6 Extended Update Support - Fixed with sudo-1.8.23-3.el7_6.1 via RHSA-2019:3205 Red Hat Enterprise Linux 7.5 Extended Update Support - Fixed with sudo-1.8.19p2-14.el7_5.1 via RHSA-2019:3204 Red Hat Enterprise Linux 7.4 Update Services for SAP Solutions - Fixed with sudo-1.8.19p2-12.el7_4.1 via RHSA-2019:3209 Red Hat Enterprise Linux 7.4 Telco Extended Update Support - Fixed with sudo-1.8.19p2-12.el7_4.1 via RHSA-2019:3209 Red Hat Enterprise Linux 7.4 Advanced Update Support - Fixed with sudo-1.8.19p2-12.el7_4.1 via RHSA-2019:3209 Red Hat Enterprise Linux 7.3 Update Services for SAP Solutions - Fixed with sudo-1.8.19p2-12.el7_4.1 via RHSA-2019:3219 Red Hat Enterprise Linux 7.3 Telco Extended Update Support - Fixed with sudo-1.8.19p2-12.el7_4.1 via RHSA-2019:3219 Red Hat Enterprise Linux 7.3 Advanced Update Support - Fixed with sudo-1.8.19p2-12.el7_4.1 via RHSA-2019:3219 Red Hat Enterprise Linux 8 - Fixed with sudo-1.8.25p1-8 via RHSA-2019:3694
