Description détaillée

OPNsense before 26.7.8 contains a command injection vulnerability that allows authenticated users with the System: Firmware privilege to execute commands as root by storing a malicious firmware mirror URL. Attackers can submit shell metacharacters through POST /api/core/firmware/set that opnsense-update evaluates with eval, and can also disable package signature verification through sed injection.
