CVE-2017-9392
Description
An issue was discovered on Vera VeraEdge 1.7.19 and Veralite 1.7.481 devices. The device provides UPnP services that are available on port 3480 and can also be accessed via port 80 using the url "/port_3480". It seems that the UPnP services provide "request_image" as one of the service actions for a normal user to retrieve an image from a camera that is controlled by the controller. It seems that the "res" (resolution) parameter passed in the query string is not sanitized and is stored on the stack which allows an attacker to overflow the buffer. The function "LU::Generic_IP_Camera_Manager::REQ_Image" is activated when the lu_request_image is passed as the "id" parameter in the query string. This function then calls "LU::Generic_IP_Camera_Manager::GetUrlFromArguments". This function retrieves all the parameters passed in the query string including "res" and then uses the value passed in it to fill up buffer using the sprintf function. However, the function in this case lacks a simple length check and as a result an attacker who is able to send more than 184 characters can easily overflow the values stored on the stack including the $RA value and thus execute code on the device.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
VeraEdge and Veralite devices suffer from a stack buffer overflow in the UPnP request_image action, enabling remote code execution.
Vulnerability
The VeraEdge firmware version 1.7.19 and Veralite firmware version 1.7.481 expose a UPnP service on port 3480 (also accessible via port 80 under /port_3480). The action request_image is provided for normal users to retrieve images from a connected camera. The res (resolution) parameter in the query string is passed to the function LU::Generic_IP_Camera_Manager::GetUrlFromArguments, which copies it into a stack buffer using sprintf without a length check. When more than 184 characters are supplied, the stack buffer overflows, corrupting the return address [1].
Exploitation
An attacker needs only network access to the device on the UPnP port (3480 or 80 via /port_3480). No authentication is required. The attacker sends a crafted HTTP request with an excessively long res parameter in the query string, triggering the overflow and overwriting the saved return address ($RA) on the stack [1].
Impact
Successful exploitation allows arbitrary code execution on the device. The attacker gains full control of the controller, potentially compromising all connected cameras and other home automation functions [1].
Mitigation
As of the last known information, no official firmware patch has been released for VeraEdge 1.7.19 or Veralite 1.7.481. The device may be end-of-life and no longer supported. Users should isolate the device on a separate VLAN, restrict network access to the UPnP port, and consider replacing the device if no update becomes available [1].
