Open Redirect

medium Nessus Plugin ID 121040

Language:

Synopsis

The web application accepts a parameter value that allows redirects to unrestricted locations.

Description

The remote web application contains functionality to redirect to a specific URL. This functionality is not restricted to relative URLs within the application and could be leveraged by an attacker to fool an end user into believing that a malicious URL they were redirected to is valid.

Solution

Parameters that are used to dynamically redirect must be restricted to paths within the application. If relative paths are accepted, the base path should be explicitly prepended.
