The DHCP client (udhcpc) in BusyBox before 1.20.0 allows remote DHCP servers to execute arbitrary commands via shell metacharacters in the (1) HOST_NAME, (2) DOMAIN_NAME, (3) NIS_DOMAIN, and (4) TFTP_SERVER_NAME host name options.

Security readout for executives and security teams

This flaw lets a malicious DHCP server make vulnerable BusyBox DHCP clients run commands when processing crafted network configuration values. Business risk is highest for embedded Linux, appliances, and legacy systems that obtain network settings from untrusted or compromised DHCP infrastructure. Likely exposure is legacy Linux or embedded devices using BusyBox udhcpc before 1.20.0. Public references include vendor and downstream advisories, including embedded and industrial device contexts, but the bundle does not provide a complete affected-product inventory. Treat this as a legacy embedded-device exposure issue. It is not listed as KEV in the provided data, but arbitrary command execution from DHCP can be serious where vulnerable devices trust untrusted networks. Mitigation focus: Identify systems and firmware that include BusyBox udhcpc before 1.20.0.; Apply vendor firmware or package updates where available.; Check vendor advisories for product-specific fixes and supported upgrade paths..
