php-fpm security.limit_extension issue

I run Nginx + php5-fpm with Ajenti on Debian. This is the issue error.log gives me on one of the websites:

2015/03/16 10:44:03 [error] 1487#0: *95 FastCGI sent in stderr: “Access to the script ‘/srv/test/index.php/author-login’ has been denied (see security.limit_extensions)” while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: xxx.xx, request: “GET /index.php/author-login HTTP/1.1”, upstream: “fastcgi://unix:/var/run/ajenti-v-php-fcgi-test2-php-fcgi-0.sock:”, host: “xxx.xxx”, referrer: “xxx.xxx

How can I repair security.limit_exceptions?

Just to add a simple fix for problems i was having. Mine was a small mistake in the nginx config that made PHP fpm try and deal with all the file (.js .jpg etc) This was because i had location / { all i had to do is change this so fpm only dealt with php files location ~ /.*\.php$ {

FPM’s security.limit_extension setting is used to limit the extensions of the main script it will be allowed to parse. It prevents malicious code from being executed. The default value is simply .php It can be configured in /etc/php5/fpm/pool.d/www.conf

Though your issue like is elsewhere. The first thing I would check is that the cgi.fix_pathinfo setting in your /etc/php5/fpm/php.ini file is set to:

cgi.fix_pathinfo=0

See our tutorial on setting up Nginx and PHP for more info.

Using PHP-FPM

If If i set

cgi.fix_pathinfo=0

Then i get an access denied message from owncloud. And could not make it work by uncommenting

security.limit_extensions = .php .php3 .php4 .php5 .php7

So i had to go back to cgi.fix_pathinfo=1
