high Tenable Cloud Security Plugin ID 413233

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Flysystem is an open source file storage library for PHP. The whitespace normalisation using in 1.x and
2.x removes any unicode whitespace. Under certain specific conditions this could potentially allow a
malicious user to execute code remotely. The conditions are: A user is allowed to supply the path or
filename of an uploaded file, the supplied path or filename is not checked against unicode chars, the
supplied pathname checked against an extension deny-list, not an allow-list, the supplied path or filename
contains a unicode whitespace char in the extension, the uploaded file is stored in a directory that
allows PHP code to be executed. Given these conditions are met a user can upload and execute arbitrary
code on the system under attack. The unicode whitespace removal has been replaced with a rejection
(exception). For 1.x users, upgrade to 1.1.4. For 2.x users, upgrade to 2.1.1. (CVE-2021-32708)
