Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Silverstripe XSS in Director, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A low level XSS vulnerability has been found in the Framework affecting http redirection via the Director::force_redirect method. Attempts to redirect to a url may generate HTML which is not safely escaped, and may pose a risk of XSS in some environments. This vulnerability is marked low as it is difficult to exploit, as any injected HTML will only be returned from the server if the Location HTTP header is also sent, meaning that any user browsing the site would not be exposed to the body of the response before their browser redirects them.
