A group of Danish security researchers have discovered a vulnerability in Cable Modems in Europe and potentially worldwide that leverages a function of Broadcom chips called the spectrum analyzer. Spectrum Analyzer is a debugger tool usually only available on the internal network. But the researchers say they’ve discovered more ways to allow access to an endpoint. Theoretically this could allow for some social engineering including a remote MIT (man in the middle attack), through a browser as well as other ways to compromise an endpoint.
