At least 28 backdoors and many other vulnerabilities were discovered in the firmware of the popular FTTH ONT router, which is widely deployed throughout South America and Southeast Asia.
FTTH ONT stands for Fiber-to-the-Home optical network terminal (Fiber-to-the-Home Optical Network Terminal). These are special devices placed at the end of fiber optic cables. Their role is to convert optical signals sent through optical fibers into classic Ethernet or WiFi connections.
FTTH ONTs are usually installed in apartment buildings or in homes or businesses that choose gigabit subscriptions.
In a report published last weekteam, ο ερευνητής ασφαλείας Pierre Kim ανέφερε ότι εντόπισε πάρα πολλά κενά ασφαλείας με τα FiberHome HG6245D και FiberHome RP2602, δύο μοντέλα δρομολογητών FTTH ONT που αναπτύχθηκαν από την κινεζική εταιρεία FiberHome Networks.
The report describes both the positive and the negative issues with both router models and their firmware.
For example, on the positive issues is that both devices do not expose the management panel through either externalς διεπαφής IPv4, καθιστώντας αδύνατη την επίθεση εναντίον του πίνακα ιστού μέσω του Διαδικτύου. Επιπλέον, η δυνατότητα διαχείρισης Telnet, η οποία συχνά χρησιμοποιείται για κατάχρηση από τα botnets, είναι απενεργοποιημένη από προchoice.
However, Kim says that FiberHome engineers apparently failed to activate, as the device firewall is only active on the IPv4 interface and not on IPv6, allowing direct access to all of the router's internal services, as long as one knows the IPv6 address. .
Kim described a long list of backdoors and vulnerabilities he discovered in the device, which he claims could be used by intruders to take over ISP infrastructure.
