Expression Web 4 Php Install Ubuntu. Thank you for research to discover and publish this, but I must say, that your title is a bit misleading, or frankly said just sensationalistic and technically wrong. What you describe in the article is simply a bad usage of the infamous `eval` function which is, as to its nature, the easiest way to allow remote code execution.

I want to deserialize data from php serialize array in node js I found in many questions use JSON.stringify() to serialize and for deserialize use JSON.parse but unable to do the same and not find. JavaScript tool to unserialize data taken from PHP. It can parse 'serialize()' output, or even serialized sessions data. Join GitHub today.

This is covered in dozens of articles and is among the first things every Javascript developer should learn. But most of all the usage is NOT in Node.js itself but in a rather unpopular npm package that was not updated in 4 years and has a mere 11 dependents, according to npmjs.org This is a simple problem with all open source packages: everyone who thinks about using an open source third party dependency should review the source code before trusting it, if used in security context. This is why the `node-serialize` package has no serious dependants as everybody in their right mind would scan a serialization library for the unprotected usage of `eval`.

So again, thanks for your work in discovering this, but please adapt the title to the facts! Hi Lukas, This blog post intent to cover deserialization bugs in a fairly new JavaScript environment, Node.js. As Node.js does not provide serialization/deserialization APIs, there is third party modules providing this functionality to Node.js. The issues discussed in the blog post is present in not just one library, but in other libraries like serialize-to-js as well.

This is not so simple and straightforward as that. The unserilalize()/deserialize() function provided by these modules are designed to convert strings to objects, which may contain functions inside them, but not to execute them.

We are actually abusing the IIFE property to make this into a working exploit. So it is not as simple as old school eval() where JavaScript code is passed into eval() resulting in code execution. The exploitation technique and payload is different here and is not covered anywhere as far as I know, please correct me if I am wrong. I am a security engineer myself. I don’t know how many developers did a code review on Apache Commons, the Java library known for deserialization issues () before using it. It is not practical in real world for a developer to do code review and then use a library/module.

It has to be the job of a security engineer/ consultant to do code review once the code is written and thats how I found this. And finally I agree, the title might be confusing for people who judge early. So I have updated the tl;dr section with enough information to avoid confusion.

Data serialized by PHP should be deserialized by PHP, since it is a format proper to that environment. It would be unwise to use a JavaScript deserialize function when you have the possibility to do that in PHP itself. Survey Programs Hp-50. Source Code Penjualan Barang Dengan Php. Create A Pdf Using Php. So do this in PHP: // Deserialize your data $data11 = unserialize($row['data']); // JSON encode it, and output that echo json_encode($data11); Then in JavaScript, assuming you get the PHP data in a variable response (via an Ajax request): var data = JSON.parse(response); I suppose you already have the code to perform the Ajax request. If not, look at the many Q&A on that subject, for example.
