| Title | Router Multilaser Backup File Information Disclosure |
|---|
| Description | Version multilaser routers are vulnerable to an attack where it is possible to download the device's backup file containing your login credentials in plain text.
To reproduce, access one of the targets available in shodan (link below) and enter the path /param.file.tgz right after the link.
Like for example http://x.x.x.x:8080/param.file.tgz.
It will start downloading a file and inside it contains the credentials.
They follow the pattern in which the word "guest" always comes, right after it comes a number, then a random character and finally, the user and password to log in to the device.
guest 4 € admin nikem199131
Where in this case, the credentials are:
User: admin
Password: nikem199131
Shodan search:

Shodan dork:
WWW-Authenticate: Basic realm="Multilaser " 401
