CVSS: 9.0EPSS: 32%CPEs: 47EXPL: 21CVE-2019-14287 – sudo 1.8.27 - Security Bypass
https://notcve.org/view.php?id=CVE-2019-14287
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. En Sudo anteriores a 1.8.28, un atacante con acceso a una cuenta Runas ALL sudoer puede omitir ciertas listas negras de políticas y módulos PAM de sesión, y puede causar un registro incorrecto, mediante la invocación sudo con un ID de usuario creado. Por ejemplo, esto permite la omisión de la configuración root y el registro USER= para un comando "sudo -u \#$((0xffffffff))". • https://www.exploit-db.com/exploits/47502 https://github.com/n0w4n/CVE-2019-14287 https://github.com/shallvhack/Sudo-Security-Bypass-CVE-2019-14287 https://github.com/CMNatic/Dockerized-CVE-2019-14287 https://github.com/axax002/sudo-vulnerability-CVE-2019-14287 https://github.com/N3rdyN3xus/CVE-2019-14287 https://github.com/DewmiApsara/CVE-2019-14287 https://github.com/MariliaMeira/CVE-2019-14287 https://github.com/edsonjt81/CVE-2019-14287- https://github.com/SachinthaDeSilva-cmd& • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •

The SHA-2 digest support in the sudoers plugin in sudo after 1.8.7 allows local users with write permissions to parts of the called command to replace them before it is executed. La compatibilidad con SHA-2 digest en el plugin sudoers en sudo, en versiones posteriores a la 1.8.7, permite que usuarios locales con permisos de escritura en partes del comando llamado los reemplace antes de ejecutarlo. • http://www.openwall.com/lists/oss-security/2015/11/18/22 https://bugzilla.redhat.com/show_bug.cgi?id=1283635 https://www.sudo.ws/repos/sudo/rev/0cd3cc8fa195 https://www.sudo.ws/repos/sudo/rev/24a3d9215c64 https://www.sudo.ws/repos/sudo/rev/397722cdd7ec • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2017-1000368
Todd Miller's sudo version 1.8.20p1 and earlier is vulnerable to an input validation (embedded newlines) in the get_process_ttyname() function resulting in information disclosure and command execution. La versión 1.8.20p1 y anteriores de sudo de Todd Miller es vulnerable a una validación de entradas (nuevas líneas embebidas) en la función get_process_ttyname() que da lugar a una revelación de información y la ejecución de comandos. It was found that the original fix for CVE-2017-1000367 was incomplete. A flaw was found in the way sudo parsed tty information from the process status file in the proc filesystem. A local user with privileges to execute commands via sudo could use this flaw to escalate their privileges to root. • http://www.securityfocus.com/bid/98838 https://access.redhat.com/errata/RHSA-2017:1574 https://kc.mcafee.com/corporate/index?page=content&id=SB10205 https://security.gentoo.org/glsa/201710-04 https://usn.ubuntu.com/3968-1 https://usn.ubuntu.com/3968-2 https://www.sudo.ws/alerts/linux_tty.html https://access.redhat.com/security/cve/CVE-2017-1000368 https://bugzilla.redhat.com/show_bug.cgi?id=1459152 https://access.redhat.com/security/cve/CVE-2017-1000367 https:& • CWE-20: Improper Input Validation •
