Debian 7 wheezy has virtualbox guest additions inbuilt. So after installing debian on virtualbox the guest addition features are immediately available. However the guest additions bundled with debian is general of older version compared to the latest virtualbox version. So its a good idea to install the latest virtualbox guest additions.
Here is a quick command that will tell the version of virtualbox guest additions currently installed.
# lsmod | grep -io vboxguest | xargs modinfo | grep -iw version version: 4.1.18_Debian
So in the default installation of debian 7, the guest additions version 4.1.18 are inbuilt. So it needs to be updated.
The same command can be run in 2 steps instead.
# lsmod | grep -i vboxvboxsf 29071 1 vboxvideo 12437 1 drm 183952 2 vboxvideo vboxguest 148611 6 vboxsf # modinfo vboxguestfilename: /lib/modules/3.2.0-4-amd64/updates/dkms/vboxguest.ko version: 4.1.18_Debian license: GPL description: Oracle VM VirtualBox Guest Additions for Linux Module author: Oracle Corporation srcversion: 2B8D846D07E45862D5C0169 alias: pci:v000080EEd0000CAFEsv00000000sd00000000bc*sc*i* depends: vermagic: 3.2.0-4-amd64 SMP mod_unload modversions #

VirtualBox Guest Additions installer You appear to have a version of the VBoxGuestAdditions software on your system which was installed from a different source or using a different type of installer. If you installed it from a package from your Linux distribution or if it is a default part of the system then we strongly recommend that you cancel this installation and remove it properly before installing this version.

All lines should show as done. Especially the line "Building the VirtualBox Guest Additions kernel modules". Once done, restart the guest. Also check the guest additions version again.

If the cdrom has got mounted as readonly and not allowing to execute file then remount it using the mount command.
# mount -o remount,exec /dev/sr0 mount: warning: /media/cdrom0 seems to be mounted read-only.
Replace /dev/sr0 with the device name. The device name can be found by running just mount command.
So now you should have the latest virtualbox guest additions installed in the Debian guest. Enjoy!
