Suspicious query through advanced_search_result.php - 1054: Unknown column?

[jamus]

Hi,

 

We have had two emails sent to the store owner a containing massive query which appears to have been made through the advanced_search_result.php.

 

The contents starts ....

 

1054: Unknown column 'tablename.gz.manufacturers_id' in 'on clause'

select count(distinct p.products_id) as total from products

 

continues with loads of ....

where p.products_id in ('175','345','346','347','348','349','351','352','353','354','357','361','368','369','371','372','374','375','406','411','415','416','417','418','419','420','421','426','427','428','429'

 

and goes on...

 

_1 how is the email generated automatically and sent to the store owner?

_2 what does the contents mean? Is someone try to do something bad??
