## Technical details

OS command injection via unsanitized interface name parameter in QinQ VLAN configuration. An authenticated user with QinQ edit privilege can store a malicious 'if' parameter value containing shell metacharacters, which is later interpolated into ifconfig shell commands executed as root. The vulnerability affects versions 2.7.0 through 2.9.0 and requires existing authentication and the specific QinQ edit privilege.
