Our honeypots frequently detect scans targeting various home automation protocol endpoints. Many of these attacks aim to exploit vulnerable consumer routers. Upon further investigation, we’ve discovered a persistent flaw affecting Linksys Smart Wi-Fi routers that allows unauthenticated remote access to sensitive information. How can the vulnerability be exploited? Go to the Linksys Smart Wi-Fi router’s public IP address in your web browser Open the developer console (F12 key) and go to the Network tab Scroll down to JNAP (there’s multiple) and click to open it The leak can also be reproduced by sending a request to this JNAP endpoint: X-JNAP-ACTION: …

On Friday, January 25, 2019, our honeypots detected opportunistic scanning activity from multiple hosts targeting Cisco Small Business RV320 and RV325 routers. A vulnerability exists in these routers that allow remote unauthenticated information disclosure (CVE-2019-1653) leading to remote code execution (CVE-2019-1652). ⚠️ WARNING ⚠️Incoming scans detected from multiple hosts checking for vulnerable Cisco RV320/RV325 routers. A vulnerability in the web-based management interface of these routers could allow an unauthenticated, remote attacker to retrieve sensitive configuration information. pic.twitter.com/OhQD55WNZD — Bad Packets Report (@bad_packets) January 25, 2019 These scans consisted of a GET request for /cgi-bin/config.exp which is the path that allows unauthenticated …

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 …
