Summary

Unprivileged users may be able to invoke privileged commands via SSH. With
the right type of network access to the hardware, a skilled user could
figure out a way to craft an SSH command to grant themselves privileged
access, allowing the user to issue all administrative commands, with the
potential to disrupt normal system operation. This patch fixes a security
vulnerability that allows a TSSC service user unauthorized access to the
attached TS7700.
