An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01c254 the value for the s_vol_dim_delta key is copied using strcpy to the buffer at 0xa0000514. This buffer is 4 bytes large, sending anything longer will cause a buffer overflow.
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 attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01c2c8 the value for the s_url key is copied using strcpy to the buffer at 0xa0001a0c. This buffer is 16 bytes large, sending anything longer will cause a buffer overflow. The destination can also be shifted by using an sn_speaker parameter between "0" and "3".
An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01c318 the value for the s_port key is copied using strcpy to the buffer at 0xa00017f4. This buffer is 6 bytes large, sending anything longer will cause a buffer overflow. The destination can also be shifted by using an sn_speaker parameter between "0" and "3".
An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01c368 the value for the s_mac key is copied using strcpy to the buffer at 0xa000170c. This buffer is 25 bytes large, sending anything longer will cause a buffer overflow. The destination can also be shifted by using an sn_speaker parameter between "0" and "3".
An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01e7d4 the value for the s_vol key is copied using strcpy to the buffer at 0xa0001700. This buffer is maximum 12 bytes large (this is the maximum size it could be, it is possible other global variables are stored between this variable and the next one that we could identify), sending anything longer will cause a buffer overflow.
An exploitable permanent denial of service vulnerability exists in Insteon Hub running firmware version 1013. The firmware upgrade functionality, triggered via PubNub, retrieves signed firmware binaries using plain HTTP requests. The device doesn't check the kind of firmware image that is going to be installed and thus allows for flashing any signed firmware into any MCU. Since the device contains different and incompatible MCUs, flashing one firmware to the wrong MCU will result in a permanent brick condition. To trigger this vulnerability, an attacker needs to impersonate the remote server "cache.insteon.com" and serve a signed firmware image.
