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 Sulu/sulu, 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 Sulu v2.0.0 through v2.6.4 are vulnerable against XSS whereas a low privileged user with an access to the “Media” section can upload an SVG file with a malicious payload. Once uploaded and accessed, the malicious javascript will be executed on the victims’ (other users including admins) browsers.
