aias Posted February 1, 2015 Share Posted February 1, 2015 Hello, I'd like to reopen an archived thread. When typing 'ZyXel 7547' into Google, this archived thread is the first result. Ref: https://forums.hak5.org/index.php?/topic/28507-open-ports-on-router-esp-port-7547/ The problem was never solved. This port comes by default as open to the WAN on many ZyXel commercial routers, and is easily made explotable. The solution to the problem is as follows: 1. Login to your device via telnet (or ssh if provided). 2. Issue the following command: sys cwmp clearall. This will stop the port listening on the WAN. That is all. - aias Quote Link to comment Share on other sites More sharing options...
