[BLUF: A critical chain of vulnerabilities in Rui's cloud-connected IoT devices allows remote code execution, with attackers able to exploit device serial numbers broadcast in plain text to gain full control of any access point worldwide. This reveals a potential backdoor rather than accidental flaws.]0:15
Key Takeaways:
• Rui devices authenticate to the cloud using a serial number hashed via SHA-256, making authentication vulnerable if the serial number is known 11:00.
• Attackers can impersonate devices and execute arbitrary commands via MQTT topics, such as "Dev config get module flow control UDP" 13:38.
• Devices broadcast serial numbers in unencrypted management frames, exposing them to any Wi-Fi sniffer 14:44.
• A full remote code execution chain exists: sniff serial number → authenticate via cloud → execute commands on any device 15:31.
[Closing statement: This vulnerability chain suggests intentional design flaws rather than accidental oversights, raising serious concerns about the security of cloud-managed IoT infrastructure.]

ah another day another vulnerability in an Internet of Things stack another router is victim to a remote code execution vulnerability but the reason why I found this one so interesting was that this is actually a cloud connected device typically the routers you see getting hacked with zero day vulnerabilities are ones that sit in your home office or maybe your mom's office right you know a small $30 router like a TP Link or a Netgear that there's a buffer overflow in the device uh but team 82 found an extremely interesting set of vulnerabilities right there are multiple vulnerabilities that when you chain them together allows you to execute a command on any Cloud connected rouie device now if you don't know who I am my name is Ed I run this channel I've been doing offensive security so hac…
