New PHP Vulnerability Exposes Windows Servers to Remote Code Execution
Details have emerged about a new critical security flaw impacting PHP that could be exploited to achieve remote code execution under certain circumstances.
The vulnerability, tracked as CVE-2024–4577, has been described as a CGI argument injection vulnerability affecting all versions of PHP installed on the Windows operating system.
According to DEVCORE security researcher, the shortcoming makes it possible to bypass protections put in place for another security flaw, CVE-2012–1823.

Microscopic black holes may explain all dark matter in the universe
In the vast expanse of the cosmos, there is much more than meets the eye. For every kilogram of visible matter in the universe, from the computer on your desk to the distant stars and galaxies, there are 5 kilograms of invisible “dark matter” that permeate our surroundings.
This enigmatic dark matter evades direct observation yet exerts its invisible pull on the visible objects around us.
Fifty years ago, renowned physicist Stephen Hawking proposed a fascinating idea about the nature of dark matter. He suggested that it might consist of a population of black holes that formed in the early stages of the universe, mere moments after the Big Bang.
Bill Gates-backed startup creates Lego-like brick that can store air pollution for centuries: ‘A milestone for affordably removing carbon dioxide from the air’
The pipe dream of carbon capture is one step closer to reality thanks to a Bill Gates-backed startup that is burying bricks made from plants.
The Washington Post detailed a “deceptively simple” procedure by Graphyte to sequester blocks of wood chips and rice hulls, calling it “a game-changer” for the industry, which has been held back by the cost ineffectiveness of other methods.
“The approach, the company claims, could store a ton of CO2 for around $100 a ton, a number long considered a milestone for affordably removing carbon dioxide from the air,” the outlet reported.
