Use the readcd
Or, provided that the CD was burnt correctly, simply read an image of the ISO filesystem with cat /dev/cdrom > image.iso
or something equivalent (e.g. with the dd command).
Using mkisofs doesn't make much sense, because the CD contains the ISO 9660 file-system already. No need to rebuild it from scratch. It is only necessary to create a raw image of the CD.
