Spoofing Downloaded Filename’s Extension in Chromium

Insufficient data validation in the File System API allows attackers to remotely bypass Windows file system restrictions via a crafted HTML page.

An attacker can easily use this vulnerability to target a victim, because the script can be manipulated to execute another command that might be used in conjunction with another vulnerability, hence raising an even bigger security concern.

Key Pointers:

  • Introduction to spoofing and how it works
  • Understanding the filename extension spoofing in Chromium
  • Understanding the vulnerability and its impact
  • Setting up the lab environment to demonstrate the exploitation of Chromium vulnerability
  • Mitigations to prevent such attacks
