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

In some cases, form messages can contain HTML markup. This is an intentional feature, allowing links and other relevant HTML markup for the given message. Some form messages include content that the user can provide. There are scenarios in the CMS where that content doesn't get correctly sanitised prior to being included in the form message, resulting in an XSS vulnerability. ### References - https://www.silverstripe.org/download/security-releases/cve-2024-53277 ## Reported by Leo Diamat from [Bastion Security Group](http://www.bastionsecurity.co.nz/)
