A security issue that could affect almost all Intel processors released in the last five years has been discovered. Researchers at the security firm Positive Technologies found an error in a system called the Intel Converged Security and Management Engine (CSME), as well as in the hardware of the chips themselves. The CSME system is used in a large number of processes on the chips, including initial authentication, and is the basis for various hardware security technologies used on Intel chipsets. It may be impossible to fully secure against this vulnerability. “This vulnerability jeopardizes everything Intel has done to build the root of trust and lay a solid security foundation on the company’s platforms,” the researchers wrote in a blog post. “The problem is not only that it is impossible to fix firmware errors that are hard-coded in the Mask ROM of microprocessors and chipsets. The larger worry is that, because this vulnerability allows a compromise at the hardware level, it destroys the chain of trust for the platform as a whole.” Security researcher Mark Ermolov gave more details about the vulnerability in a statement: “The vulnerability resembles an error recently identified in the BootROM of Apple mobile platforms, but… Read full this story
