How the Exploit Works

The vulnerability arises from an undocumented local user account named ‘ubuntu’ with a preset password and a sudoers entry that grants this account passwordless root privileges. Anyone who knows the hardcoded password can obtain root privileges via local console or equivalent administrative access, thus enabling local privilege escalation. Although a patch for this vulnerability was reported, it is incomplete as it only remediated /etc/shadow, leaving /etc/sudoers still vulnerable.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This example assumes that the attacker has gained local console or equivalent administrative access.

$ ssh ubuntu@target.example.com  // Log in to the target system using the ubuntu account
Password: [hardcoded password]  // Enter the hardcoded password
$ sudo su  // Use sudo to switch to the root user, no password required due to the sudoers entry
# whoami  // Verify that the current user is root
root

Once root access is gained, the attacker can execute any command, potentially leading to system compromise or data leakage.
