I sent this to the webappsec mailing list but thought I'd send it here
as well looking for some SQL Injection experts.

I've got a vulnerable web app with a MySQL backend where I can inject
into an INSERT query and I want to create a file. With a SELECT I
would use a UNION and then SELECT whatever INTO OUTFILE "filename" but
how do you do it with an INSERT query?
INSERT INTO size VALUES (22, (SELECT "abc" INTO OUTFILE "/tmp/test")) ;
That executes and size gets a new row with 22 and "abc" in it but it
doesn't create the file.
I also tried an UPDATE and had the same problem:
UPDATE size SET big=22 WHERE big = (SELECT "abc" INTO OUTFILE "/tmp/test");
The update happens where big="abc" but no outfile.
Can it be done?
