An exploitable buffer overflow vulnerability exists in the camera "create" feature of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17. The video-core process incorrectly extracts the "state" field from a user-controlled JSON payload, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.

On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process insecurely extracts the fields from the "shard" table of its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability. The strcpy call overflows the destination buffer, which has a size of 16 bytes. An attacker can send an arbitrarily long "region" value in order to exploit this vulnerability.

On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability. The memcpy call overflows the destination buffer, which has a size of 512 bytes. An attacker can send an arbitrarily long "url" value in order to overwrite the saved-PC with 0x42424242.

On Insteon Hub 2245-222 devices with firmware version 1012, specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability. At 0x9d01ef24 the value for the s_offset key is copied using strcpy to the buffer at $sp+0x2b0. This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.

An exploitable denial of service vulnerability exists in Insteon Hub running firmware version 1012. Leftover demo functionality allows for arbitrarily rebooting the device without authentication. An attacker can send a UDP packet to trigger this vulnerability.

In January 2018, Microsoft released an advisory and security updates for a new class of hardware vulnerabilities involving speculative execution side channels (known as Spectre and Meltdown). In this blog post, we will provide a technical analysis of a new speculative execution side channel vulnerability known as L1 Terminal Fault (L1TF) which has been assigned CVE-2018-3615 (for SGX), CVE-2018-3620 (for operating systems and SMM), and CVE-2018-3646 (for virtualization).

An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01c284 the value for the s_vol_brt_delta key is copied using strcpy to the buffer at 0xa0000510. This buffer is 4 bytes large, sending anything longer will cause a buffer overflow.

An exploitable buffer overflow vulnerability exists in Insteon Hub running firmware version 1012. The HTTP server implementation incorrectly handles the URL parameter during a firmware update request, leading to a buffer overflow on a global section. An attacker can send an HTTP GET request to trigger this vulnerability.

An exploitable buffer overflow vulnerability exists in Insteon Hub running firmware version 1012. The HTTP server implementation incorrectly handles the host parameter during a firmware update request, leading to a buffer overflow on a global section. An attacker can send an HTTP GET request to trigger this vulnerability.

An exploitable stack-based buffer overflow vulnerability exists in Insteon Hub running firmware version 1012. The HTTP server implementation unsafely extracts parameters from the query string, leading to a buffer overflow on the stack. An attacker can send an HTTP GET request to trigger this vulnerability.
