This makes it +still possible for attackers to upload malware by giving their files an image +file extension, but should prevent automatic execution on client computers when +opening those files. + +It does not protect at all from exploiting vulnerabilities in image display +programs, nor from users renaming file extensions to inadvertently execute the +contained malicious code. + +## Secure file upload serving configurations + +The following configurations serve uploaded files as static files with the +proper headers as +[mitigation against file upload risks](#mitigations-against-file-upload-risks). +Please do not simply copy&paste these configurations, but make sure you +understand what they are doing and that you have implemented them correctly. + +> Always test your own setup and make sure that it is secure! + +e.g. try uploading PHP scripts (as "example.php", "example.php.png" and +"example.png") to see if they get executed by your web server, e.g. the content +of the following sample: + +```php +GIF89ad + # Some of the directives require the Apache Headers module. If it is not + # already enabled, please execute the following command and reload Apache: + # sudo a2enmod headers + # + # Please note that the order of directives across configuration files matters, + # see also: + # https://httpd.apache.org/docs/current/sections.html#merging + + # The following directive matches all files and forces them to be handled as + # static content, which prevents the server from parsing and executing files + # that are associated with a dynamic runtime, e.g. PHP files. + # It also forces their Content-Type header to "application/octet-stream" and + # adds a "Content-Disposition: attachment" header to force a download dialog, + # which prevents browsers from interpreting files in the context of the + # web server, e.g. HTML files containing JavaScript. + # Lastly it also prevents browsers from MIME-sniffing the Content-Type, + # preventing them from interpreting a file as a different Content-Type than + # the one sent by the webserver. + + SetHandler default-handler + ForceType application/octet-stream + Header set Content-Disposition attachment + Header set X-Content-Type-Options nosniff + + + # The following directive matches known image files and unsets the forced + # Content-Type so they can be served with their original mime type. + # It also unsets the Content-Disposition header to allow displaying them + # inline in the browser. + + ForceType none + Header unset Content-Disposition + + +``` + +### NGINX config + +Add the following directive to the NGINX config, replacing the directory path +with the absolute path to the upload directory: + +```Nginx +location ^~ /path/to/project/server/php/files { + root html;

Tests `fn` as desired + * expect(fn()).to.throw(); // Bad!

Doing so is + * problematic because the `this` context will be lost when the function is + * invoked by `.throw`; there's no way for it to know what `this` is supposed + * to be. There are two ways around this problem. One solution is to wrap the + * method or function call inside of another function. Another solution is to + * use `bind`. + * + * expect(function () { cat.meow(); }).to.throw(); // Function expression + * expect(() => cat.meow()).to.throw(); // ES6 arrow function + * expect(cat.meow.bind(cat)).to.throw(); // Bind + * + * Finally, it's worth mentioning that it's a best practice in JavaScript to + * only throw `Error` and derivatives of `Error` such as `ReferenceError`, + * `TypeError`, and user-defined objects that extend `Error`.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) { + return this.emit('error', new Error('write callback called multiple times')); + } + + ts.writechunk = null; + ts.writecb = null; + + if (data != null) // single equals check for both `null` and `undefined` + this.push(data); + + cb(er); + + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} + +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + + Duplex.call(this, options); + + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.on('prefinish', prefinish); +} + +function prefinish() { + var _this = this; + + if (typeof this._flush === 'function') { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} + +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.
