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

"value": "** EN DISPUTA ** En Sudo hasta 1.8.29, un atacante con acceso a una cuenta de sudoer Runas ALL puede suplantar a un usuario inexistente invocando sudo con un uid num\u00e9rico que no est\u00e1 asociado con ning\u00fan usuario. NOTA: El responsable del software cree que esto no es una vulnerabilidad porque ejecutar un comando a trav\u00e9s de sudo como un usuario que no est\u00e1 presente en la base de datos de contrase\u00f1as local es una caracter\u00edstica intencional. Debido a que este comportamiento sorprendi\u00f3 a algunos usuarios, sudo 1.8.30 introdujo una opci\u00f3n para habilitar / deshabilitar este comportamiento con el valor predeterminado deshabilitado. Sin embargo, esto no cambia el hecho de que sudo se estaba comportando seg\u00fan lo previsto, y seg\u00fan lo documentado, en versiones anteriores."
