CVE-2015-6568
HighSummary
Wolf CMS before 0.8.3.1 allows unrestricted file rename and PHP Code Execution because the file manager does not prevent a change of a file extension to '.php' after originally using the parameter 'filename' for uploading a JPEG image. Exploitation requires a registered user who has access to upload functionality.
Risk Assessment
The organization may be exposed to malicious attacks that could lead to unauthorized code execution on the server, potentially resulting in data loss or system takeover.
Recommendation
It is recommended to update Wolf CMS to version 0.8.3.1 or later and implement additional security measures to restrict the ability to upload files with dangerous extensions.
