Hi List, I'm presently working with a semi-government ISP as a security consultant.The ISP has provided Internet access to the customers via phone lines, it's DSL. The customer is given q DSL router as a CPE. ISP people configure it with 2 IP addresses; one local and one global, and implement NAT for security. And the router is configured using both ie Global/Private IP address in a browser. I recently have been asked to find out loopholes in the mentioned system where the customer's privacy is not taken care or can be compromised. Now when I started my activities impersonating a normal customer, I found that:
1]I can nmap and discover open ports on my and neighboring IP addresses.2] This included HTTP, HTTPS, FTP, SMB, NB-SSN etc services listening for incoming connections. 3]When I try to connect to some customer's HTTP port, I'm taken to his/her DSL-router(CPE) config. page, Configuration password is asked but is blank.
Now my questions:1]What kind of tests can be carried out in order to find out what level of access can other customers gain and 2]What degree of impact can it have as far as the privacy of the customers is considered.
