    Al,

    It looks to me as though there may be a script that's allowing
writing, judging by the all-as-one-string nature of the first script
example.  Check your Apache logs to see if that string appears, and if
so, to what script it's attacking.  Then review the script.

    If you need a hand, feel free to contact me privately and we can
discuss it further.
