Oligo Security's research team recently disclosed the “0.0.0.0 Day” vulnerability. This vulnerability allows malicious websites to bypass browser security and interact with services running on an organization’s local network, potentially leading to unauthorized access and remote code execution on local services by attackers outside the network.

The issue stems from the inconsistent implementation of security mechanisms across different browsers, along with a lack of standardization in the browser industry. As a result, the seemingly innocuous IP address, 0.0.0.0, can become a powerful tool for attackers to exploit local services, including those used for development, operating systems, and even internal networks.

The impact of 0.0.0.0 Day is far-reaching, affecting individuals and organizations alike.. The discovery of active exploitation campaigns, such as ShadowRay, further underscores the urgency of addressing this vulnerability.

TL;DR: The Oligo research team has recently discovered a critical vulnerability affecting all major web browsers, enabling attackers to breach local networks. This finding, which we’ve dubbed "0.0.0.0 Day," exposes a fundamental flaw in how browsers handle network requests, potentially granting malicious actors access to sensitive services running on local devices.
