Componant 安装后 Joomla SQL 查询错误

Question

I recently installed arra user migrate and now when i go to Manage under extensions (i want to remove it) i get a server error:

Unknown column 'a.id' in 'where clause' SQL=SELECT COUNT(*) FROM n3dmx_extensions WHERE state=0 AND a.id != 1013 AND a.id != 1014 AND a.id != 1015 Unknown column 'a.id' in 'where clause' SQL=SELECT *,2*protected+(1-protected)*enabled as status FROM n3dmx_extensions WHERE state=0 AND a.id != 1013 AND a.id != 1014 AND a.id != 1015 Unknown column 'a.id' in 'where clause' SQL=SELECT COUNT(*) FROM n3dmx_extensions WHERE state=0 AND a.id != 1013 AND a.id != 1014 AND a.id != 1015

Im not sure where to go from here as this was working ok previously, ideally i don't want to have to restore from a back up. Any advice on how to fix it? I have already clicked 'Fix Database' and updated to the latest version of joomla? Where are the SQL queries stored/created?

Best Regards Donna

Found this while looking for a solution for the same issue. It seems like this issue is a result of a hack attack. It inserts something similar to below code into the getItems() function of /libraries/legacy/model/list.php file.

$query->where('a.id != 1015');

The number 1015 might be different in each case. Mine was 9417 .

More details at this forum post .

Removing the above code with get your site back to normal. But obviously this is a result of hack attack. This tells you that you need pay more attention to the security of your Joomla site.
