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.

* Advisory ID: DRUPAL-SA-CONTRIB-2014-027
* Project: NewsFlash [1] (third-party theme)
* Version: 6.x, 7.x
* Date: 2014-March-05
* Security risk: Moderately critical [2]
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
-------- DESCRIPTION
---------------------------------------------------------
Newsflash is a theme that features 7 color styles, 12 collapsible regions,
suckerfish menus, fluid or fixed widths, built-in IE transparent PNG fix, and
lots more.
The theme does not sanitize the user provided theme setting for the font
family CSS property, thereby exposing a cross-site scripting (XSS)
vulnerability.
This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "administer themes".
