Description

JUNG Smart Panel KNX firmware version L1.12.22 and prior contain an unauthenticated path traversal vulnerability in the embedded web interface. The application fails to properly validate file path input, allowing remote, unauthenticated attackers to access arbitrary files on the underlying filesystem within the context of the web server. This may result in disclosure of system configuration files and other sensitive information.
