What to do

Workaround (from the CVE record)

To mitigate this issue, ensure that systems configured to obtain network settings via DHCP in the initramfs are only booted on trusted networks. This vulnerability requires an attacker to control a DHCP server on the adjacent network segment. If network configuration via DHCP is not strictly necessary during the initramfs phase, consider using static network configuration.

About this vulnerability

A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This al…

Description

Dracut: dracut: root code execution via dhcp options command injection

A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior.
