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
Low
PR
The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
Scope
S
An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
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: Bus Pass Management System 1.0 - 'searchdata' Cross-Site Scripting (XSS)
# Date: 2022-07-02
# Exploit Author: Ali Alipour
# Vendor Homepage: https://phpgurukul.com/bus-pass-management-system-using-php-and-mysql
# Software Link: https://phpgurukul.com/wp-content/uploads/2021/07/Bus-Pass-Management-System-Using-PHP-MySQL.zip
# Version: 1.0
# Tested on: Windows 10 Pro x64 - XAMPP Server
# CVE : N/A
#Issue Detail:
The value of the searchdata request parameter is copied into the HTML document as plain text between tags. The payload cyne7<script>alert(1)</script>yhltm was submitted in the searchdata parameter. This input was echoed unmodified in the application's response.
This proof-of-concept attack demonstrates that it is possible to inject arbitrary JavaScript into the application's response.
