# Software Link: https://download-media.code-projects.org/2020/11/Blood_Bank_In_PHP_With_Source_code.zip
# Version: 1.0
# Tested on: Windows/Linux, Apache 2.4.54, PHP 8.2.0
# CVE : CVE-2023-46020

-------------------------------------------------------------------------------

# Description:

The parameters rename, remail, rphone, and rcity in the /file/updateprofile.php file of Code-Projects Blood Bank V1.0 are susceptible to Stored Cross-Site Scripting (XSS). This vulnerability arises due to insufficient input validation and sanitation of user-supplied data. An attacker can exploit this weakness by injecting malicious scripts into these parameters, which, when stored on the server, may be executed when other users view the affected user's profile.

Vulnerable File: updateprofile.php

Parameters: rename, remail, rphone, rcity

# Proof of Concept:
----------------------

1. Intercept the POST request to updateprofile.php via Burp Suite
2. Inject the payload to the vulnerable parameters
3. Payload: "><svg/onload=alert(document.domain)>
4. Example request for rname parameter:

---
