The expected structure includes a "type" attribute to instruct the server which type of object to create on deserialization. We can also use the script to play with deserialization. However I couldn’t find any resource that explained deserialization/object injection bugs in Node.js. Remote Code Execution On DotNetNuke (CVE-2017-9822) Kerentatan pada DNN - Framework yang banyak dipakai sebagai company profile dan coorporate website. The resulting request will ultimately look like this. Kaliko CMS RCE in admin interface (used FastJSON, which has insecure type name handling by default) Nancy RCE (RCE via CSRF cookie) Breeze RCE (used Json.NET with TypeNameHandling.Objects) DNN (aka DotNetNuke) RCE (RCE via user-provided cookie) Both the white paper[pdf] and the slides[pdf] are available on the Black Hat site.

Reading Time: 10 minutes We looked at around 300 DotNetNuke deployments in the wild and discovered that one in five installations was vulnerable to CVE-2017-9822. This module exploits a deserialization vulnerability in DotNetNuke (DNN) versions 5.0.0 - 9.3.0-RC. Vulnerable versions store profile information for users in the DNNPersonalization cookie as XML. Test case 1.5 – Like Test case 1 but the ViewState cookie isn't sent by the server Developers can remove ViewState from becoming part of an HTTP Request (the user won't receive this cookie). The expected structure includes a "type" attribute to instruct the server which type of object to create on deserialization.

By clicking the link we send in the serialized object as a GET parameter. Session 02: Tools & Methodologies. A remote, authenticated attacker can exploit this vulnerability by sending a request containing a malicious WASPostParam value to the target server. OSWE Preparation.

That includes governmental and banking websites.

Rails Remote Code Execution Vulnerability Explained Arbitrary code execution with Python pickles. The class must thus be defined before the deserialization. Web Traffic Inspection Interacting with Web Listeners with Python Source Code Recovery.

A malicioususer can decode one of such cookies and identify who that user is, and possiblyimpersonate other users and even upload malicious code to the server.

Contribute to timip/OSWE development by creating an account on GitHub. Vulnerable versions store profile information for users in the DNNPersonalization cookie as XML. The vulnerability is due to an untrusted deserialization of data when the WASPostParam cookie is present in the request.

I thought to do some research on this and after spending some time I was able to exploit a deserialization bug to achieve arbitrary code injection.
