Novastar · Novastar Cx40 · CVE-2025-3007
**Name of the Vulnerable Software and Affected Versions**
Novastar CX40 versions up to 2.44.0
**Description**
A critical issue affects the `getopt` function of the `/usr/nova/bin/netconfig` file in the NetFilter Utility component. The manipulation of the `cmd`, `netmask`, `pipeout`, or `nettask` arguments leads to a stack-based buffer overflow. The exploit has been publicly disclosed.
**Recommendations**
For Novastar CX40 versions up to 2.44.0, as a temporary workaround, consider disabling the `getopt` function in the `/usr/nova/bin/netconfig` file until a patch is available. Restrict access to the NetFilter Utility component to minimize the risk of exploitation. Avoid using the `cmd`, `netmask`, `pipeout`, or `nettask` arguments in the affected `getopt` function until the issue is resolved.
