NB: All tags and branches in this repository are past their end of life, so the vulnerability will not be fixed. The advisory is posted on the request of the researcher, for the information of anyone who might still use this software.

Impact

There is a security vulnerability in eZ Publish Legacy, affecting the dfscleanup.php script and the _getFileList function of the eZDFSFileHandlerMySQLiBackend class (kernel/private/classes/clusterfilehandlers/dfsbackends/mysqli.php). The vulnerability allows an attacker with local shell access and sufficient privileges to run dfscleanup.php to perform a union-based SQL injection against the eZ Publish MySQL database, potentially exposing sensitive data such as user credentials.

It is known to affect the branch 2019.03, and it may well affect other branches.
