Command injection vulnerability exists in the “Logging” page of the web-based configuration utility. An authenticated user with low privileged network access for the configuration utility can execute arbitrary commands on the underlying OS to obtain root SSH access to the TropOS 4th Gen device.

By making minor configuration changes to the TropOS 4th Gen device, an authenticated user with the ability to run user level shell commands can enable access via secure shell (SSH) to an unrestricted root shell. This is possible through abuse of a particular set of scripts and executables that allow for certain commands to be run as root from an unprivileged context.

The “Diagnostics Tools” page of the web-based configuration utility does not properly validate user-controlled input, allowing an authenticated user with high privileges to inject commands into the command shell of the TropOS 4th Gen device. The injected commands can be exploited to execute several set-uid (SUID) applications to ultimately gain root access to the TropOS device.
