The Zarzadzonie Kontem plugin for WordPress is prone to an arbitrary file-upload vulnerability because it fails to adequately validate files before uploading them.
An attacker may leverage this issue to upload arbitrary files to the affected computer; this can result in arbitrary code execution within the context of the vulnerable application.
