Background
The io.github.skylot:jadx-core package is an open-source library used for decompiling Android APK files. It provides a tool called JADX, which parses resource files and saves the decompiled results. This package is vulnerable to a file override issue when parsing style files, which can lead to the overwriting of other files in the directory where the decompile is saved.
Vulnerability Detail
The vulnerability arises from an escape problem with the style file in JADX. When a resource file is parsed, the getResAlias function is used to handle the filename. However, the type 'style' returns the original filename directly, allowing an attacker to take a malicious file originally of type 'raw', modify its type to 'style', and trick JADX into overwriting other files in the directory. This vulnerability does not involve true path traversal, but it can still result in unauthorized file modifications.
