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
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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
None
I
There is no impact on the integrity of the system; the attacker does not gain the ability to modify any files or information on the target system.
Availability
None
A
There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

# Description about Software :
***************************
Joomla Content Management System.
Content (com_content) is the component which handles the display of content;
users can view at the frontend of your site and, as an administrator, you can edit the content.
##########################################################################################
According to the CVE-2008-6923 =>
****************************************
SQL injection vulnerability in the content component (com_content) 1.0.0
for Joomla! allows remote attackers to execute arbitrary SQL commands via the
Itemid parameter in a blogcategory action to index.php.
##########################################################################################
# Impact :
**********
Joomla Content Components 1.x [ and other versions may vulnerable ]
component for Joomla is prone to an SQL-injection vulnerability because it fails to sufficiently
sanitize user-supplied data before using it in an SQL query.
Exploiting this issue could allow an attacker to compromise the application, access
or modify data, or exploit latent vulnerabilities in the underlying database.
A remote attacker can send a specially crafted request
to the vulnerable application and execute arbitrary SQL commands in application`s database.
Further exploitation of this vulnerability may result in unauthorized data manipulation.
An attacker can exploit this issue using a browser.
