IMPACT:
Exposure of sensitive information, Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Lantronix SCS820/1620

DESCRIPTION:
c0ntex has reported some vulnerabilities in Lantonix Secure Console
Server, which can be exploited by malicious, local users to gain
escalated privileges.

1) Insecure pipe permissions in "/tmp" can be exploited via symlink
attacks to read arbitrary files with escalated privileges.

2) A directory traversal vulnerability in the console command
interface can be exploited to run shell commands (e.g.
"../../../bin/bash"). This can also be exploited by the sysadmin user
to run shell commands with root privileges.

3) A boundary error in edituser can be exploited to execute arbitrary
code with root privileges.

SOLUTION:
The vulnerabilities have reportedly been fixed in firmware version
4.4.
