Detailsinfo

A vulnerability was found in Vera VeraEdge and Veralite (the affected version unknown). It has been classified as critical. This affects the function eval of the file proxy.sh of the component Web User Interface. The manipulation of the argument url as part of a Parameter leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered on Vera VeraEdge 1.7.19 and Veralite 1.7.481 devices. The device provides a web user interface that allows a user to manage the device. As a part of the functionality the device firmware file contains a file known as proxy.sh which allows the device to proxy a specific request to and from from another website. This is primarily used as a method of communication between the device and Vera website when the user is logged in to the https://home.getvera.com and allows the device to communicate between the device and website. One of the parameters retrieved by this specific script is "url". This parameter is not sanitized by the script correctly and is passed in a call to "eval" to execute "curl" functionality. This allows an attacker to escape from the executed command and then execute any commands of his/her choice.

The weakness was published 06/17/2019 as not defined mailinglist post (Bugtraq). The advisory is shared at seclists.org. This vulnerability is uniquely identified as CVE-2017-9388 since 06/02/2017. The exploitability is told to be easy. It is possible to initiate the attack remotely. A authentication is necessary for exploitation. Technical details are known, but no exploit is available.
