An eighteen-year-old significant vulnerability known as “0.0.0.0 Day” has been found by researchers at Oligo Security and impacts all of the major online browsers, including Chromium, Firefox, and Safari.

This flaw makes it possible for malicious websites to communicate with local network services of an enterprise while evading browser security. This could result in unwanted access and the ability for attackers from outside the network to remotely execute code on local services.

The problem is caused by the uneven use of security features in various browsers and the absence of industry standards in the browser sector.

Attackers can specifically use the IP address 0.0.0.0, which is frequently used as a placeholder or default address, to get access to local services, such as those utilized for operating systems, development, and even internal networks.
