Hi
I encountered the following message in the server logwatch this morning:
GET /moodle/user/view.php?course=1&id=1%20and%201=2%20union%20select%20CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c),CONCAT(0x27,0x7c,0x5f,0x7c)%20/* HTTP/1.1 with response code(s) 404 1 responses
Any idea what vulnerability this is trying to exploit?
Thanks
