**Name of the Vulnerable Software and Affected Versions**
WAYOS FBM-220G version 24.10.19
**Description**
A flaw exists in WAYOS FBM-220G version 24.10.19 related to command injection. Manipulation of the arguments `upnp waniface`, `upnp ssdp interval`, and `upnp max age` within the `sub 40F820` function of the `rc` file can allow for remote execution of commands. The vendor was contacted regarding this issue but did not provide a response.

As a temporary workaround, consider restricting or disabling the use of the `upnp waniface`, `upnp ssdp interval`, and `upnp max age` arguments.
Disable the `sub 40F820` function if possible.
Avoid using the `rc` file if it is not essential for the operation of the system.
