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 \"file\" as one of the service actions for a normal user to read a file that is stored under the /etc/cmh-lu folder. It retrieves the value from the \"parameters\" query string variable and then passes it to an internal function \"FileUtils::ReadFileIntoBuffer\" which is a library function that does not perform any sanitization on the value submitted and this allows an attacker to use directory traversal characters \"../\" and read files from other folders within the device."}, {"lang": "es", "value": "Se detect\u00f3 un problema en los dispositivos VeraEdge versi\u00f3n 1.7.19 y Veralite versi\u00f3n 1.7.481 de Vera.
