An Open Redirect vulnerability is discovered in the Carbon Management Console.


The following pages in the management console were found to be vulnerable to open redirect attacks, in the products mentioned here.

  • XACML Policy Administration
  • Identity Provider Management
  • Workflow Management
  • User Management

An attacker can attack the above UI components, by modifying some query parameters that contain a URL value in the management console context. They can modify the respective query parameter value such that the management console will redirect the request to the specified URL.


An attacker aware of the management console origin, can modify the query parameter values to a URL value of a malicious site, and trick a user to invoke the modified URL via email or a neutral website. This redirects the user to the malicious site and the attacker may successfully launch a phishing scam and steal user credentials or other sensitive information, or harm in any other way.
