--[ 00 - Introduction
The purpose of this article is to detail the research that I have recently
completed regarding the D-Link DNS 343 ShareCenter.
--[ 00.1 - Background
The D-Link ShareCenter 4-Bay Network Storage Enclosure (DNS-343) connects
to your network instead of to a computer so everyone on your network can
back up content to one central location. Plus, it lets you share your
stored content across your network and over the Internet so family members,
friends and employees can access it no matter where they are.
--[ 01 - Command Injection
Within the DNS-343 web directory is a folder named "maintenance" that
contains a number of ASP scripts that are related to maintenance tasks that
can be performed. The script by the name of "test_mail.asp" caught my
attention, and that is what we will focus on for now.
--[ 01.1 - Vulnerable code analysis
The DNS-343 utilizes the goAhead web server, which contains a functionality
called goForms, which basically stores CGI in memory. This is important to
know as the previously mentioned "test_mail.asp" posts directly to the
"/goform/Mail_Test" endpoint. Code for this particular goForm can be found
within the "webs" binary.
int __fastcall sub_27D24(int a1)
{
int v1; // r4@1
int *v2; // r10@1
char *v3; // r8@1
char *v4; // r6@1
char *v5; // r5@1
char *v6; // r7@1
int v7; // r12@1
char *v8; // r0@4
char *v10; // [sp+10h] [bp-230h]@1
char *v11; // [sp+14h] [bp-22Ch]@1
char s; // [sp+18h] [bp-228h]@4
v1 = a1;
v2 = &dword_8D968;
v3 = sub_4D340(a1, (int)"f_auth", &byte_7F4B4);
v11 = sub_4D340(v1, (int)"f_username", &byte_7F4B4);
v10 = sub_4D340(v1, (int)"f_password", &byte_7F4B4);
v4 = sub_4D340(v1, (int)"f_smtpserver", &byte_7F4B4);
v5 = sub_4D340(v1, (int)"f_sender", &byte_7F4B4);
v6 = sub_4D340(v1, (int)"f_sendto", &byte_7F4B4);
system("rm /tmp/email_*");
v7 = (unsigned __int8)*v3 - 49;
if ( *v3 == 49 )
v7 = (unsigned __int8)v3[1];
if ( v7 )
{
sprintf(&s, "email -h %s -p 25 -a 0 -s %s -d %s -t", v4, v5, v6);
v2 = &dword_8D968;
v8 = &s;
}
else
{
sprintf(&s, "email -h %s -p 25 -a 1 -u %s -w %s -s %s -d %s -t", v4,
v11, v10, v5, v6);
v8 = &s;
}
*v2 = system(v8);
*v2 = sub_27C80();
return THISISAREDIRECT(v1, "web/maintenance/test_mail_result.asp");
}
As can be seen in the above psuedo code, the form data passed to the goForm
endpoint is never sanitized, and then used directly in a system call. This
can be leveraged by an unauthenticated remote attacker to execute code as
root and take complete control of the device.
--[ 01.2 - Remote exploitation
Exploiting this issue is trivial, and can be achieved by simply sending a
post request containing a command injection string within one of the fields
that are affected to the "/goform/Mail_Test" endpoint. I achieved this by
sending a post request with the following data.
f_smtpserver=;touch /tmp/gulftech;
The above post request successfully creates the file named "gulftech"
within the /tmp directory as the root user.
