Ensure root path integrity
Mô tả
The root user can execute any command on the system and could be fooled into executing programs unintentionally if the PATH is not set correctly. Including the current working directory (.) or other writable directory in root's executable path makes it likely that an attacker can gain superuser access by forcing an administrator operating as root to execute a Trojan horse program. Audit: root's login PATH must not contain ::, a trailing :, '.', non-directories, or directories not owned by root or writable by group/other.
