A recently discovered flaw in Broadcom's Wi-Fi setup software allows attackers within radio range of affected routers to execute code with root privileges. This vulnerability does not require network passwords or any pairing steps, making it particularly concerning. Security researcher Quentin Kaiser revealed that this flaw can be exploited on home gateways from three Belgian internet providers, with one demonstration showing an attacker reading the Wi-Fi password directly from the device. This incident raises alarms about the security of many routers that use Broadcom chips, as it potentially exposes users to unauthorized access and control over their home networks. It is crucial for affected users and internet service providers to take immediate action to protect their devices from exploitation.
