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/comments, 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

The silverstripe/comments module, the cwp/starter-theme and the cwp/watea-theme include an outdated version of jQuery by default, which contains XSS vulnerabilities if user input is used in certain contexts. Though no known exploit has been found for these in the existing usage, user customisation to these themes could have made them exploitable. CWP 2.0.0 has been released with the fixed cwp/stater-theme and silverstripe/comments module, and SilverStripe 4.2.0 will be released with the fixed silverstripe-themes/simple theme.
