sql-foo.pl is a complete rewrite
sql_enum.pl. sql_enum.pl was written four years back - it was ugly, incomprehensible, and getting it to work was a pain in the butt. And it was not even a complicated script. I guess I was still learning Perl back then. sql-foo.pl is much cleaner. However, there is no new features. And yes, it's only for GET. Coding it to support POST is quite trivial.
I was planning to make it automatically query for all columns in a tables (assuming that you start with table enumeration), but in my experience, even if you are able to enumerate say a table, it does not mean that you can enumerate columns. Also, even if you are able to enumerate columns, it still does not guarantee that you can enumerate the records. If you can do this from a single query string, than you've found an extremely weak web application.
Exploiting SQL injection still requires a lot of manual work - sql-foo.pl is the tool that you can use if you are planning to enumerate a lot of records from the database. Anyways, if you are looking for a better tool, go
here. I've never tested absinthe before because it requires
Mono version 1 and above and mono requires the latest gcc, and in addition, I always go for the
low hanging fruits. Blind SQL injection is just too much work.
Oh ya - I haven't really tested it. And yes, even after 5 years, SQL injection is still rampant.
