Shell script is kind of brittle when it comes to proper quoting of user-specified arguments etc so you need to be really careful here. Perhaps wrapping the call in PHP is not such a bad idea (although PHP too has a bit of a track record when it comes to security problems .... /me ducks) and make really really sure you use proper quoting everywhere in the script and in everything which invokes it. And keep in mind that security checks in JavaScript are ineffective; somebody could simply be connecting directly to the CGI script, without going through your form (or with JavaScript disabled).

As such, it's not very hard to split on & with IFS='&'. IFS=& query_string - Google Search brings up some matches but I would regard all of them with extreme suspicion. If you see a variable interpolation without double quotes around it, run away.

NAME
uri_urn - URI utilities, URN scheme SYNOPSIS
package require Tcl 8.2 package require uri::urn ?1.1.2? uri::urn::quote url uri::urn::unquote url _________________________________________________________________ DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to handle urls using the urn scheme. COMMANDS
uri::urn::quote url This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its result. uri::urn::unquote url This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters, and returns the modified urls as its result.
