OVERVIEW


The above WSO2 products are vulnerable to XML External Entity Processing (XXE), reflected Cross Site Scripting (XSS) and stored XSS attacks.



DESCRIPTION

An attacker with access to the WSO2 Management Console can input a malicious XXE script in the try-it tool UI menu or can directly attack with xml input and disclose any file located in the file system.

The reflected and stored XSS vulnerabilities allow deployment of malicious code in the application by means of providing specifically crafted url to a user.


 IMPACT


The XXE vulnerability allows reading an arbitrary file on an underlying operating system for users having access to the Management Console, or even facilitate Server Side Request Forgery attacks.

In addition to that, reflected and stored XSS vulnerabilities enable attackers to inject client side scripts into some pages in the Management Console. This reflects the attack back to the user’s browser and will execute the injected code, which may generate malicious page results that will mislead the victim or harm otherwise.
