Name of the Vulnerable Software and Affected Versions Insteon Hub version 1012

Description Multiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel. 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. In the e l command, at address 0x9d016c94, the value for the as c key is copied using strcpy to the buffer at $sp+0x2b0. This buffer is 32 bytes large, and sending anything longer will cause a buffer overflow.

Recommendations For Insteon Hub version 1012, as a temporary workaround, consider restricting access to the PubNub message handler for the "cc" channel until a patch is available. Avoid sending authenticated HTTP requests with specially crafted commands to the vulnerable channel. Additionally, restrict the use of the strcpy function in the e l command to prevent buffer overflows. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
