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/framework, 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 high level XSS vulnerability has been discovered in the SilverStripe framework which causes links containing hash anchors (E.g. href="#anchor") to be rewritten in an unsafe way. The rewriteHashlinks option on SSViewer will rewrite these to contain the current url, although without adequate escaping, meaning that HTML could be injected via injecting unsafe values to any page via the querystring. Due to the nature of this issue it is likely that a large number of SilverStripe sites are affected.
