An authenticated user with access to the CDP component of NOKIA IMPACT is able to upload files with arbitrary extensions.

The deviceImport function parses every file received with a csv_parse function. We managed to load a non-csv file adding at the beginning of it the following line followed by our payload.

We uploaded PHP Webshell in a path served by Apache (in our case /opt/[redacted]/5/) and got code execution as apache user.
