File write

This executable can write data to local files.

Comment
It can be used to write files using a specially crafted SMBIOS file that can be read as a memory device by dmidecode. Generate the file with dmiwrite and upload it to the target.
- --dump-bin, will cause dmidecode to write the payload to the destination specified, prepended with 32 null bytes.
- --no-sysfs, if the target system is using an older version of dmidecode, you may need to omit the option.
```
make dmiwrite
echo DATA >/path/to/temp-file
./dmiwrite /path/to/temp-file x.dmi
```
Unprivileged
This function can be performed by any unprivileged user.
```
dmidecode --no-sysfs -d x.dmi --dump-bin /path/to/output-file
```
Remarks
The content is corrupted or otherwise altered by the process, thus it might not be suitable for handling arbitrary binary data.
