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
s init event command, at address 0x9d01ea88, the value for the s event offset 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
As a temporary workaround, consider restricting access to the PubNub message handler for the "cc" channel until a patch is available.
Restrict the length of data sent to the buffer at
$sp+0x2b0 to prevent buffer overflow.
Avoid using the strcpy function to copy the value for the s event offset key to the buffer at $sp+0x2b0 until the issue is resolved.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
