https://notcve.org/view.php?id=CVE-2019-19232
19 Dec 2019 — In Sudo through 1.8.29, an attacker with access to a Runas ALL sudoer account can impersonate a nonexistent user by invoking sudo with a numeric uid that is not associated with any user. NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo as a user not present in the local password database is an intentional feature. Because this behavior surprised some users, sudo 1.8.30 introduced an option to enable/disable this behavior with the default being disabl... • http://seclists.org/fulldisclosure/2020/Mar/31 • CWE-284: Improper Access Control •
CVSS: 7.5EPSS: 1%CPEs: 1EXPL: 0CVE-2019-19234 – sudo: by using ! character in the shadow file instead of a password hash can access to a run as all sudoer account
https://notcve.org/view.php?id=CVE-2019-19234
19 Dec 2019 — In Sudo through 1.8.29, the fact that a user has been blocked (e.g., by using the ! character in the shadow file instead of a password hash) is not considered, allowing an attacker (who has access to a Runas ALL sudoer account) to impersonate any blocked user. 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).

04 Nov 2019 — Sudo through 1.8.29 allows local users to escalate to root if they have write access to file descriptor 3 of the sudo process. This occurs because of a race condition between determining a uid, and the setresuid and openat system calls. The attacker can write "ALL ALL=(ALL) NOPASSWD:ALL" to /proc/#####/fd/3 at a time when Sudo is prompting for a password. NOTE: This has been disputed due to the way Linux /proc works. It has been argued that writing to /proc/#####/fd/3 would only be viable if you had permiss... • https://gist.github.com/oxagast/51171aa161074188a11d96cbef884bbd • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

15 Oct 2019 — 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... • https://www.exploit-db.com/exploits/47502 • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •
