18-year-old Browser Vulnerability impacts MacOS and Linux devices

Date: 8 August 2024.

The Hacker News report that "researchers have discovered a new 0.0.0.0 Day impacting all major web browsers that malicious websites could take advantage of to breach local networks".

"The critical vulnerability exposes a fundamental flaw in how browsers handle network requests, potentially granting malicious actors access to sensitive services running on local devices."

A seemingly harmless IP address such as 0.0.0.0 could be weaponized to exploit local services.

"Put differently, the issue is as simple as a malicious web page sending requests to 0.0.0.0 and a port of its choosing that could then be processed by services running locally on that same port, leading to unintended consequences."

In response web browser (providers) are expected to block access to 0.0.0.0 completely, thereby deprecating direct access to private network endpoints from public websites.
