CVE-2019-19232 (GCVE-0-2019-19232)

Vulnerability from cvelistv5 – Published: 2019-12-19 20:37 – Updated: 2024-08-05 02:09
VLAI?
Summary
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
