Something wrong with your Exec directives. Here's something from _ICS, ICSS Web Programming Guide_ (not available in PDF, only HTML or CD library):

>>>>

Error 500: Bad script request - /QSYS.LIB/CGI.LIB/HTMLSRC.FILE not executable

Cause:Incorrect match of Exec rule.
Solution:See Description of "Forbidden - Path not valid for this server"

<<<<

>>>>

Error 403: Forbidden -- Path not valid for this server

Whenever a "Forbidden - Path not valid for this server" occurs when running a CGI program, the configuration directives have not been specified correctly.
Cause when a CGI program is requested:When a CGI program is requested, a Pass directive appears before an Exec directive. For example:

Pass qsys.lib/htmlcgi.lib/*

Exec qsys.lib/htmlcgi.lib/*

In this example any programs in library htmlcgi will not run because the Pass occurred before the Exec. Once a Pass condition is true, the server does not go further.
Solution when a CGI program is requested:Change the order of the directives to correct the problem. For example:

Exec /qsys.lib/htmlcgi.lib/*

Pass /qsys.lib/htmlcgi.lib/*

Note: Since the value mapped /qsys.lib/htmlcgi.lib/ is the same for both Pass and Exec, the combination above would correct a problem with using an incorrect directive but also leaves a directive in the file that could never be used.
The best way to avoid this problem is to use one of the following:
1.Use Exec and Pass directives with mapping:

Pass /doc/* qsys.lib/html.lib/*

Exec /cgi-bin/* qsys.lib/html.lib/*

2.Put the CGI programs in a separate library:

Exec /qsys.lib/htmlcgi.lib/*

Pass /qsys.lib/htmldoc.lib/html.file/*

Cause when a document is requested:When a document is requested, an Exec directive appears before a Pass directive. For example:

Exec qsys.lib/html.lib/*

Pass qsys.lib/html.lib/*

In this example any documents in library html will not be found because the Exec occurred before the Pass.
Solution when a document is requested:Change the order of the directives to correct the problem. For example:

Pass /qsys.lib/html.lib/*

Exec /qsys.lib/html.lib/*

Note: Since the value mapped /qsys.lib/html.lib/is the same for both Pass and Exec, the combination above would correct a problem with using an incorrect directive but also leaves a directive in the file that could never be used.
The best way to avoid this problem is to use one of the following:

Pass /doc/* qsys.lib/html.lib/*

Exec /cgi-bin/* qsys.lib/html.lib/*

2.Put the CGI programs in a separate library:

Exec /qsys.lib/htmlcgi.lib/*

Pass /qsys.lib/htmldoc.lib/html.file/*
