Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Ezsystems/ezpublish kernel, 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

Access control based on object state is mishandled. This is a policy you can use in your roles to limit access to content based on specific object state values. Due to a flawed earlier update, these limitations were ineffective in releases made since February 16th 2022. They would grant access to the given content regardless of the object state. Depending on how your frontent is designed, knowing the URL to the content may or may not be required to access it. If you are using object state limitations in your roles, this issue is critical. Please apply the fix as soon as possible.
