Script Summary

Detects Huawei modems models HG530x, HG520x, HG510x (and possibly others...) vulnerable to a remote credential and information disclosure vulnerability. It also extracts the PPPoE credentials and other interesting configuration values.

Attackers can query the URIs "/Listadeparametros.html" and "/wanfun.js" to extract sensitive information including PPPoE credentials, firmware version, model, gateway, dns servers and active connections among other values.

This script exploits two vulnerabilities. One was discovered and reported by Adiaz from Comunidad Underground de Mexico (http://underground.org.mx) and it allows attackers to extract the pppoe password. The configuration disclosure vulnerability was discovered by Pedro Joaquin (http://hakim.ws).
