Authentication Bypass in LG Innotek Camera

An authentication bypass vulnerability exists in LG Innotek camera models LND7210 and LNV7210R. The vulnerability allows a malicious actor to gain access to camera information including user account information.

LG LNB*, LND*, LNU*, and LNV* smart network camera devices have broken access control. Attackers are able to download /updownload/t.report (aka Log & Report) files and download backup files (via download.php) without authenticating. These backup files contain user credentials and configuration information for the camera device. An attacker is able to discover the backup filename via reading the system logs or report data, or just by brute-forcing the backup filename pattern. It may be possible to authenticate to the admin account with the admin password.
