Description
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to insufficient validation of filenames when downloading files, as a unicode RTL order character in the downloaded file name can be used to

extension. A remote attacker can trick the victim into downloading malicious files to the system.
