CVE-2017-9389 — An issue was discovered on Vera VeraEdge 1.7.19 and Veralite 1.7.481 devices

High CVSS 9

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.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
