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 Ezsystems/ezpublish legacy, 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

This security advisory fixes a vulnerability in eZ Publish Legacy, and we recommend that you install it as soon as possible if you are using Legacy via the LegacyBridge. Installations where all modules are disabled may be vulnerable to XSS injection in the module name. This is a rare configuration, but we still recommend installing the update, which adds the necessary input washing. To install, use Composer to update to one of the "Resolving versions" mentioned above, or apply this patch manually: https://github.com/ezsystems/ezpublish-legacy/commit/4697bff700e8cf95d5847ea19dad3479a77b02d9
