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.
