Technical details

The vulnerability is an OS command injection in the del_staticrule function of the ioos web backend, where the rule_name parameter is concatenated unsanitized into a system() call without filtering shell metacharacters. The attack requires prior authentication and network access to the router's web interface. Exploitation grants arbitrary command execution with root privileges, leading to full device compromise.
