I saw some people using this code in the “.htaccess” file to disable script execution:

<Files ~ "(php\.ini|\.htaccess|\.php.?|\.pl|\.cgi|\.spc|\.jsp|\.cfm|\.passwd)$">
order deny,allow
deny from all
</Files>

This code is not secure, and can be bypassed by uploading a “testpage.PhP” file as an example.

This code has a case sensitive regular expression.

Note: <FilesMatch> is similar to <Files> with this problem

One solution:

# secure directory by disabling script execution
AddHandler cgi-script .php .pl .py .jsp .asp .htm .shtml .sh .cgi
Options -ExecCGI
