Wouldn't you need a particular Apache configuration for mod_cgi to
launch /bin/sh?  e.g., /cgi-bin/ configured as a ScriptAlias, and/or
*.sh configured with an appropriate handler?  Granted that's likely a
common configuration, but a site without a configured /cgi-bin/ should
be immune to this attack even if their /bin/sh is a symlink to
/bin/bash.
