Impact

The impact of this path traversal and arbitrary extension is limited (creation of arbitrary files and
appending data to existing files) but when combined with the SQL Injection, the exported data
RESTRICTED DIFFUSION 9 / 9
can be controlled and a webshell can be uploaded. Attackers can use that to execute arbitrary
PHP code on the server with the permissions of the webserver.
