Summary
On Appear TV XC5000 and XC5100 devices with firmware 3.26.217, it is possible to read OS files with a specially crafted HTTP request (such as GET /../../../../../../../../../../../../etc/passwd) to the web server (fuzzd/0.1.1) running the Maintenance Center on port TCP/8088. This can lead to full compromise of the device.
