Details
A vulnerability was found in Vera VeraEdge and Veralite 1.7.19. It has been declared as critical. This vulnerability affects the function LU::JobHandler_LuaUPnP::RunLua of the component Web User Interface. The manipulation of the argument code as part of a POST Request leads to a improper authentication vulnerability (Lua). The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:
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 allows a user to install applications written in the Lua programming language. Also the interface allows any user to write his/her application in the Lua language. However, this functionality is not protected by authentication and this allows an attacker to run arbitrary Lua code on the device. The POST request is forwarded to LuaUPNP daemon on the device. This binary handles the received Lua code in the function "LU::JobHandler_LuaUPnP::RunLua(LU::JobHandler_LuaUPnP *__hidden this, LU::UPnPActionWrapper *)". The value in the "code" parameter is then passed to the function "LU::LuaInterface::RunCode(char const*)" which actually loads the Lua engine and runs the code.
The weakness was released 06/17/2019 as not defined mailinglist post (Bugtraq). The advisory is available at seclists.org. This vulnerability was named CVE-2017-9389 since 06/02/2017.
