Technical details

An information disclosure vulnerability exists in WuzhiCMS versions up to 4.1.0 within the Attachment API component. The flaw is located in the config/listimage function of the /index.php?m=attachment&f=index&v=upload endpoint. The root cause is a failure to implement proper authorization checks (CWE-862), allowing unauthenticated remote attackers to trigger the 'action=config' parameter.
