The Unarchiver supports them too.

Thanks. I prefer that one over StuffIt. It is open source and does not ask for an admin password to install. – Thilo Dec 9 '09 at 11:32
You can check what gets installed (check out Pacifist), but likely the password is needed only because of the location of the install. – Nerdling Dec 9 '09 at 11:52
@Nerdling: Probably. I really wished the standard installers offered a way to install just into the current user account, rather than system-wide. – Thilo Dec 10 '09 at 0:55

You may use the freeware StuffIt Expander 2010.
It supports over 30 archive file formats, including CAB.

The Unarchiver failed to open my particular CAB file ("error decrunching"), so I tried another pretty open-source app, called keka, which could do it.

There is also a cross-platform command-line tool that works: cabextract.
