Linux Sudo Open Root Access Vulnerability Discovered

A vulnerability has been discovered in Sudo, one of the most important, powerful, and commonly used utilities that comes as a core command installed on almost every UNIX and Linux-based operating system.

The vulnerability in question is a Sudo security policy bypass flaw that could allow a malicious user or a program to execute arbitrary commands as root on a targeted Linux system. The bug requires a system to have a non-standard configuration. In other words, Linux computers are not vulnerable by default.

When executing commands on a Linux operating system, unprivileged users can use the "Superuser do" command to execute commands as root just by specifying the user ID "-1" or "4294967295."

The vulnerability tracked as CVE-2019-14287 does require a nonstandard configuration but nonetheless does open the door to unauthorized users. The Sudo bug allows users to bypass the nonroot restriction by simply using -u#-1 in the command line.
