Description

There exists a buffer overflow vulnerability in certain Cable Modem Spectrum Analyzer interfaces. This overflow is exploitable, but since an exploit would differ between every make, model, and firmware version (which also differs from ISP to ISP), this module simply causes a Denial of Service to test if the vulnerability is present.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
