An issue was discovered on Libre Wireless LS9 LS1.5/p7040 devices. There is a luci_service Read_ NVRAM Direct Access Information Leak. The luci_service deamon running on port 7777 provides a sub-category of commands for which Read_ is prepended. Commands in this category are able to directly read the contents of the device configuration NVRAM. The NVRAM contains sensitive information, such as the Wi-Fi password (in cleartext), as well as connected account tokens for services such as Spotify.
