An issue was discovered on EE 4GEE HH70VB-2BE8GB3 HH70_E1_02.00_19 devices. Hardcoded root SSH credentials were discovered to be stored within the "core_app" binary utilised by the EE router for networking services. An attacker with knowledge of the default password (oelinux123) could login to the router via SSH as the root user, which could allow for the loss of confidentiality, integrity, and availability of the system. This would also allow for the bypass of the "AP Isolation" mode that is supported by the router, as well as the settings for multiple Wireless networks, which a user may use for guest clients.

The installer for the Alcatel OSPREY3_MINI Modem component on EE EE40VB 4G mobile broadband modems with firmware before EE40_00_02.00_45 sets weak permissions (Everyone:Full Control) for the "Web Connecton\EE40" and "Web Connecton\EE40\BackgroundService" directories, which allows local users to gain privileges, as demonstrated by inserting a Trojan horse ServiceManager.exe file into the "Web Connecton\EE40\BackgroundService" directory.
