SQL injection hack attempt

Question

I have a script that saves irregular strings in the url and look what someone tried to run

OPENED: /index.php?function=data:,   METHOD: GET   PORT: 36606   
OPENED: /index.php?classified_path=data:,?         METHOD: GET         PORT: 49650 
OPENED: /index.php?base==data:,         METHOD: GET         PORT: 48062
OPENED: /index.php?G_JGALL[inc_path]=data:,         METHOD: GET         PORT: 33185
OPENED: /index.php?G_JGALL[inc_path]=data:,         METHOD: GET         PORT: 51399 

What does it mean? I googled G_JGALL and found nothing but this https://github.com/sakti/fuzfuz/blob/master/data/rfi/rfi.txt which i don't understand.. and this http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-2158

What kind of an attack is this and should I worry about?

I'm not using any gallery system on my website.

If I understood your linked CVE correctly you don't need to care about if you don't have installed a software called jGallery 1.3 . Somebody, proberbly a script kiddie, tried to check for this vulnerability. You may could check for the user agent (if it is not something like a typical browser user agent) and block all requests from that user agent or that IP.
