The software that controls wireless networking chipsets made by Realtek Semiconductor contains a critical vulnerability that could allow attackers to compromise home routers. The flaw exists in a firmware component called miniigd that’s present in router models based on Realtek chipsets. The vulnerability was discovered by Ricky Lawshae, a researcher with Hewlett-Packard’s TippingPoint Digital Vaccine Labs. Exploitation does not require authentication, the ZDI team said in an advisory published Friday.”]
