Technical details
The RO CSVI extension for Joomla (versions prior to 9.11.0) contains an improper access control vulnerability (CWE-284). An unauthenticated remote attacker can trigger the creation of arbitrary directories on the server by sending specially crafted requests to the extension. The root cause is a failure to validate user authorization before executing directory creation logic. While the vulnerability is limited to directory creation rather than file uploads or execution, it represents a breakdown in the security boundary of the application's file management system. The issue is resolved in version 9.11.0.
