The injected code would be displayed on the front-end of the site as follows:
Depending on the server configuration and software versions being used, this may or may not result in a security issue. If you are using a software package that was installed via a package manager, then the issue likely won’t be an issue. Even if the package is installed via a direct download, the issue may be mitigated by the server software being able to parse the type of file being uploaded. If, however, the file is being uploaded via FTP, the issue may be exploited due to the file’s nature. The file type being uploaded is likely to be considered unsafe.
