What an attacker can do

The source says when sudo does not prompt for a password (the process runs as root, NOPASSWD is configured, or a recent sudo timestamp cache exists), the sudoPassword value is interpreted by sh as a shell command, allowing a remote unauthenticated attacker to execute arbitrary OS commands. Vendor/CNA’s CVSS 4.0 assessment (base score 9.2/10) rates confidentiality, integrity and availability impact as high.
