Forum Strange mysql error - Are our Forums being probed?
 

For the past 2 weeks, I've been getting mysql errors like the following:

Code:
Database error in vBulletin 4.0.3:
Invalid SQL:

SELECT filename,attachmentid
FROM attachment
WHERE postid= 3153499;

MySQL Error : Unknown column 'postid' in 'where clause'
Error Number : 1054
Request Date : Tuesday, May 25th 2010 @ 03:01:46 PM
Error Date : Tuesday, May 25th 2010 @ 03:04:32 PM
Script : http://[our_site].com/cron.php?rand=1274817700
Referrer : http://[our_site].com/air-travel-forum/1188118-pressurized-cans-checked-baggage.html
IP Address : 173.173.58.120
Username : Unregistered
Classname : vB_Database
MySQL Version :
Note that the postid number, 3153499, is always the same and is a non-existent postid number. The script and referrer page constantly change as do the IP addresses.

Is this some kind of probing of our system? Or, do I have a problem in our database that needs work?

Thanks. -- Rik
