Raritan Console Servers Access Privileges Escalation and Default Login
------------------------------------------------------------------------

SUMMARY

<http://www.raritan-ap.com/> Dominion SX is "a secure console server for
local and remote access to serially managed servers and other serial
devices via SSH/Telnet and Web browser".

Two vulnerabilities were discovered in Raritan's console server solutions.

DETAILS

Vulnerable Systems:
* DSX16, DSX32, DSX4, DSX8, DSXA-48 (Mips and Intel)

DSX Raritan Console Servers come with two accounts that do not have a
password. Normal users are not supposed to get access to the underlying
Linux, but they can use the busybox environment to gain elevated
privileges. Further the password used to protect the root password can be
cracked by utilizing brute forcing techniques.

Patch Availability:
After reporting it to Raritan has released a fix:
