CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	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	Low	C	There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity	Low	I	Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the 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.

When you come back on banlist.php, the script will be activated again. The only way to delete it is to delete the line using PHPMYADMIN or another SQL manager. --------------------------------------------------------------------------------- View - screenshot under E107 v1.0.2 (localhost): http://i.imgur.com/TfSn1nv.png screenshot in the source code: http://i.imgur.com/KnMCfua.png --------------------------------------------------------------------------------- ********************************************* Impact noted: -May cause problems to the owner. He becomes vulnerable when he goes in the banning section if an attacker successes to enter and makes a redirection to a malicious URL/script (EG. cookie stealer) -May cause problems to the user. If the user's banned IP tries to connect to the website, he is vulnerable because the reason of the ban appears.If the ban reason field is infected AND linked to this IP, the user incurs the risk of malicious redirection and/or undergoes bugs. -As there is apparently no character limit, an XSS worm may be writable into these fields. *********************************************
