Technical details

The del_vlan_group function in the ioos web backend fails to sanitize the vlan_name parameter before passing it to a system() call via snprintf. An authenticated attacker can inject shell metacharacters to execute arbitrary commands with root privileges. The vulnerability requires prior authentication to obtain a valid token, and exploitation is straightforward via a crafted HTTP GET request to /protocol.csp.
