CVE-2019-19232

sudo: attacker with access to a Runas ALL sudoer account can impersonate a nonexistent user

Published Dec 19, 2019 CVSS 3.1 · 7.5 High EPSS 3.3% KEV · Not listed
Description
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 disabled. However, this does not change the fact that sudo was behaving as intended, and as documented, in earlier versions
