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.
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.

# Impact :
***********
Guangzhou China Enonomic Bidding Co Ltd 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 or with any SQL Injector Tool.
Reflected XSS (or Non-Persistent) :
***************************************
The server reads data directly from the HTTP request and reflects it back in the HTTP response.
Reflected XSS exploits occur when an attacker causes a victim to supply dangerous content
to a vulnerable web application, which is then reflected back to the victim and executed by the
web browser. The most common mechanism for delivering malicious content is to include
it as a parameter in a URL that is posted publicly or e-mailed directly to the victim.
URLs constructed in this manner constitute the core of many phishing schemes, whereby
an attacker convinces a victim to visit a URL that refers to a vulnerable site. After the site reflects
the attacker's content back to the victim,the content is executed by the victim's browser.
