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 Symbiote/silverstripe multivaluefield, 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 potential deserialisation vulnerability has been identified in the symbiote/silverstripe-multivaluefield which could allow an attacker to exploit implementations of this module via object injection. Support for handling PHP objects as values in this module has been deprecated, and the serialisation technique has been switched to using JSON for handling arrays. As well as this, a potential XSS (cross-site scripting) vulnerability has been identified and remediated.
