A vulnerability was found in Wolf CMS up to 0.8.3.0 (Content Management System). It has been classified as critical. Affected is an unknown functionality of the file admin/plugin/file_manager/browse/ of the component File Manager. The manipulation of the argument filename
as part of a JPEG Image leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
Wolf CMS before 0.8.3.1 allows unrestricted file rename and PHP Code Execution because admin/plugin/file_manager/browse/ (aka the filemanager) 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.
