Editing Cable modem (section)

== Known vulnerabilities ==
In January 2020, a vulnerability affecting cable modems using [[Broadcom]] chipsets was disclosed and named [[Cable Haunt]]. Security researchers say that the vulnerability affects hundreds of millions of devices. Exploits are possible because of the use of default credentials in the [[spectrum analyzer]] component of the modem (mostly used for debugging purposes) accessible through a network [[port (network)|port]] which is open by default in the vulnerable models.<ref>{{cite journal|url=https://www.zdnet.com/article/hundreds-of-millions-of-cable-modems-are-vulnerable-to-new-cable-haunt-vulnerability/|title=Hundreds of millions of cable modems are vulnerable to new Cable Haunt vulnerability|journal=ZDNet}}</ref><ref>{{Cite web|url=https://arstechnica.com/information-technology/2020/01/exploit-that-gives-remote-access-affects-200-million-cable-modems/|title=Exploit that gives remote access affects ~200 million cable modems|last=Goodin|first=Dan|date=2020-01-13|website=Ars Technica|language=en-us|access-date=2020-01-15}}</ref>
