CVE-2021-23521 (opens in a new tab)How to fix?
Upgrade juce-framework/JUCE to version 6.1.5 or higher.
Overview
juce-framework/JUCE is an open-source cross-platform C++ application framework for creating high quality desktop and mobile applications, including VST, VST3, AU, AUv3, RTAS and AAX audio plug-ins.
Affected versions of this package are vulnerable to Link Following. This vulnerability is triggered when a malicious archive is crafted with an entry containing a symbolic link.
When extracted, the symbolic link is followed outside of the target dir allowing writing arbitrary files on the target host. In some cases, this can allow an attacker to execute arbitrary code.
The vulnerable code is in the ZipFile::uncompressEntry function in juce_ZipFile.cpp and is executed when the archive is extracted upon calling uncompressTo() on a ZipFile object.
