This tweet mentions a great WAF bypass for client side path traversal vulnerability. Client side path traversal means the attacker can manipulate the path to access restricted files or directories from the client side, bypassing web application firewall (WAF) protections that usually protect server side. Unfortunately, the tweet does not provide the specific payload or vendor for the WAF bypass. However, it's important to understand that such bypasses can allow attackers to access unauthorized files or sensitive data through the client interface, which may lead to further exploitation. Stay cautious and ensure your web applications validate and sanitize client-side inputs properly to prevent such attacks.
