CVE-2017-9391
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 "URL" 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 query string. This function then calls "LU::Generic_IP_Camera_Manager::GetUrlFromArguments" and passes a "pointer" to the function where it will be allowed to store the value from the URL parameter. This pointer is passed as the second parameter $a2 to the function "LU::Generic_IP_Camera_Manager::GetUrlFromArguments". However, neither the callee or the caller in this case performs a simple length check and as a result an attacker who is able to send more than 1336 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.
A stack buffer overflow in Vera VeraEdge and Veralite UPnP service allows remote unauthenticated attackers to execute arbitrary code via a crafted URL parameter.
Vulnerability
The Vera VeraEdge version 1.7.19 and Veralite version 1.7.481 devices contain a stack buffer overflow vulnerability in the LU::Generic_IP_Camera_Manager::REQ_Image function, which is invoked when lu_request_image is passed as the id parameter in the query string. The URL parameter is not sanitized and is stored on the stack without a length check. An attacker can send more than 1336 characters to overflow the buffer, overwriting the return address and other stack values [1][2]. The UPnP service is exposed on port 3480 and also accessible over port 80 via "/port_3480" [1].
Exploitation
An attacker can send a crafted HTTP request to the UPnP service on port 3480 or via port 80 using the "/port_3480" path. The request must contain the id=lu_request_image parameter and a URL parameter with more than 1336 characters. No authentication is required, and the attacker does not need prior access to the camera or network [1][2].
Impact
Successful exploitation allows remote, unauthenticated attackers to achieve arbitrary code execution on the device. The attacker gains full control of the affected Vera hub, which can be used to further compromise other devices on the local network or exfiltrate data [1][2].
Mitigation
As of the publication date, Vera had not released a patch for this vulnerability. Users are advised to restrict access to port 3480 and the /port_3480 URL via firewall rules to untrusted networks. The affected devices may be at end-of-life; contacting Vera for possible firmware updates or migrating to supported hardware is recommended [1][2].
