WinRAR File Extension Spoofing Code Execution Exploit

In WinRAR versions prior to 6.23, there is a vulnerability that allows attackers to execute arbitrary code. This vulnerability occurs when a user tries to open a harmless file within a ZIP archive. The issue arises when the ZIP archive contains a benign file, such as a regular .PDF file, and also a folder with the same name as the benign file. During an attempt to access the benign file, the contents of the folder, which may include executable content, are processed, leading to the execution of arbitrary code.
