CVE-2021-32708 - High Severity Vulnerability

Vulnerable Library - league/flysystem-1.0.55

Abstraction for local and remote filesystems

Dependency Hierarchy: - cache/filesystem-adapter-0.3.3 (Root Library) - :x: **league/flysystem-1.0.55** (Vulnerable Library)

Found in base branch: main

Vulnerability Details

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.

Vulnerable library is located in /3rd-party/google-api/. We're not hooked into Google API in any live features yet (will use later for Google home alerts / Google translate), so it causes no attack vector yet in Open Crypto Tracker. Patch it for next release.
