There are tons of resources which explain what settings features should be enabled and disabled when using PHP and the values certain settings should be i. XSS is client side, there is no way in which this could ever be used to read source code on the server. If you think this is possible you need to lean more about XSS, this is a very serious venerability and not understanding the basics of this venerability is extremely dangerous.
It's relatively easy to make a configuration mistake that will temporarily disable PHP execution, so why take the risk? For any decent app the only thing that needs to reside in the public folder is an index.
Everything else should be one directory above that is not accessible from the outside. Add a comment. Active Oldest Votes. SQL Injection under mysql can be used to read source code. Improve this answer. Community Bot 1.
FTP means that source code is transmitted in plain text Rook Gopher still exists. FTP will always exist. The question is why people still use it. And the answer probably has to do with the fact that SFTP requires a shell account or rssh, etc an isn't supported on Windows. Searching through config files for hardcoded passwords is seriously the easiest way to priv-esc and pwn networks Rook - LFI is entirely possible. Imagine e. Show 3 more comments.

This means that when your browser makes a request to read a PHP file, the web server does not serve up the file to you - instead, it executes the file using one of several possible PHP. Pan Php File Manager. It manages uploaded images and document files. In short, it manages the uploaded file, and allows you to do whatever you want with the file, especially if it is an image, and as many times as you want.
It is the ideal class to quickly integrate file upload in your site. There is a compile error: md5. Here is a simple patch which fixes this problem:fix-md5. This module is typlically used to handle file uploads without passing them to backend server. Here is a simple example from this module with slight modification. Subdirectories 1 and 05 are both randomly selected and should exist before uploading.
Hashed subdirectory is optional. File is renamed to a 10 digits to avoid conflict in case a file with the same name exists. This module implements a mechanism of resumable file upload aka partial upload.
It means a big file can be splitted into severl segments and then uploaded one by one in seperate Post requests. Client is responsible for choosing an unique Session-ID which is an identifier of a file being uploaded as well as the name of file saved in server.
Yes, I can achieve my goal by using the file name as Session-ID. Apply this patch to allow Session-ID to contain dot. Yet, at least half of them share common errors; in many cases programmers simply copy the code from something that works, without even attempting to understand what it really does. What follows is not a complete working download script, but rather a set of issues you should be aware about and that will allow you to write better code.
Guessing is not too difficult and in a few tries, an attacker could obtain configuration or password files. Anything is better than blindly accept requests. If you need to restrict access to a file, you should generate encrypted, one-time IDs, so you can be sure a generated path can be used only once.
This is a very widespread problem and unfortunately even the PHP manual is plagued with errors. There is no such thing in HTTP. You may add those headers if you want, but they do absolutely nothing. Sadly, this wrong example is present even in the PHP manual. The author must have been really frustrated and added three Content-Type headers. What would it be like to not having to worry about old versions of Internet Explorer? Note: the quotes in the filename are required in case the file may contain spaces.
The code above will fail in IE6 unless the following are added:. Now, the use of Cache-Control is wrong in this case, especially to both values set to zero, according to Microsoft, but it works in IE6 and IE7 and later ignores it so no harm done. If you still get strange results when downloading especially in IE , make sure that the PHP output compression is disabled, as well as any server compression sometimes the server inadvertently applies compression on the output produced by the PHP script.
Historically it had some performance issues and while the documentation claims there are no memory problems, real-life scenarios beg to differ — output buffering and other subtle things.
