Over 19,000 Orange Livebox ADSL modems are leaking their WiFi credentials

On Friday, December 21, 2018, our honeypots observed an interesting scan consisting of a GET request for /get_getnetworkconf.cgi. Upon further investigation, we found this traffic was targeting Orange Livebox ADSL modems. A flaw exists in these modems that allow remote unauthenticated users to obtain the device’s SSID and WiFi password. To assess the amount of devices vulnerable to this flaw, we obtained a list of Orange Livebox modems from Shodan. Of the 30,063 IPv4 hosts found, our scans revealed: 19,490 leaking their WiFi credentials (SSID/password) in plaintext 2,018 not leaking any information, but still exposed to the internet 8,391 not responding …
