CVE-2025-63533 Overview
A cross-site scripting (XSS) vulnerability exists in the Blood Bank Management System 1.0 within the updateprofile.php and rprofile.php components. The application fails to properly sanitize or encode user-supplied input before rendering it in the response. An attacker can inject malicious JavaScript payloads into the rname, remail, rpassword, rphone, and rcity parameters, which are then executed in the victim's browser when the page is viewed.
Critical Impact
This stored XSS vulnerability allows attackers to execute arbitrary JavaScript in victims' browsers, potentially stealing session cookies, performing actions on behalf of users, or redirecting to malicious sites within the Blood Bank Management System application.
Affected Products
- Shridharshukl Blood Bank Management System 1.0
- updateprofile.php component
- rprofile.php component

Technical Details for CVE-2025-63533
Vulnerability Analysis
This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting (XSS). The vulnerability has been assigned a CVSS 3.1 score of 5.4 (Medium severity) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N.
The CVSS vector indicates:
- Attack Vector (AV:N): Network-accessible, exploitable remotely
- Attack Complexity (AC:L): Low complexity to exploit
- Privileges Required (PR:L): Low-level privileges required (authenticated user)
- User Interaction (UI:R): Requires victim to view the malicious content
- Scope (S:C): Changed scope - can affect components beyond the vulnerable component
- Confidentiality Impact (C:L): Low confidentiality impact
- Integrity Impact (I:L): Low integrity impact
- Availability Impact (A:N): No availability impact
The EPSS (Exploit Prediction Scoring System) probability is 0.031% with a percentile of 8.437, indicating relatively low likelihood of exploitation in the wild.
Root Cause
The root cause of this vulnerability is improper input validation and output encoding in the Blood Bank Management System's profile management functionality. The updateprofile.php and rprofile.php components accept user input through multiple parameters (rname, remail, rpassword, rphone, rcity) and render this data back to the browser without proper sanitization or HTML entity encoding.
When user-controlled data is directly embedded into HTML output without escaping special characters like <, >, ", and ', an attacker can break out of the intended HTML context and inject arbitrary script tags or event handlers.
Attack Vector
The attack is network-based and requires the attacker to have low-level privileges (an authenticated user account) within the Blood Bank Management System. The attacker submits malicious JavaScript payloads through the profile update functionality. When another user (such as an administrator) views the attacker's profile or the affected page, the malicious script executes in their browser session.
This is a stored (persistent) XSS attack, as the malicious payload is saved to the application's database and served to all users who view the affected content. The attacker could leverage this vulnerability to steal session tokens, perform unauthorized actions, deface the application, or redirect users to phishing sites.
Detection Methods for CVE-2025-63533
Indicators of Compromise
- Unusual JavaScript code appearing in user profile fields (rname, remail, rpassword, rphone, rcity)
- Profile data containing HTML tags such as <script>, <img>, or event handlers like onerror, onload
- Database entries with encoded script payloads in profile-related tables
- Web server logs showing suspicious parameter values in requests to updateprofile.php or rprofile.php
- Reports of unexpected browser behavior or redirects when viewing user profiles
Detection Strategies
Organizations running the Blood Bank Management System should implement the following detection strategies:
Web Application Firewall (WAF) Rules: Deploy rules to detect and block common XSS payloads in form submissions, particularly for the affected parameters.
Input Validation Monitoring: Monitor application logs for submissions containing HTML special characters or JavaScript keywords in profile fields.
Database Auditing: Regularly audit the database for stored content containing potentially malicious scripts in user profile tables.
Browser-Based Detection: Implement Content Security Policy (CSP) headers to detect and report inline script execution attempts.
Monitoring Recommendations
- Enable detailed logging for all requests to updateprofile.php and rprofile.php
- Configure alerts for form submissions containing script tags or JavaScript event handlers
- Monitor for unusual patterns of profile updates or mass exploitation attempts
- Implement anomaly detection for sudden changes in user profile content patterns
- Review access logs for the affected PHP files to identify potential exploitation attempts
How to Mitigate CVE-2025-63533
Immediate Actions Required
- Implement input validation to reject or sanitize special characters in all user-supplied input fields
- Apply output encoding using functions like htmlspecialchars() or htmlentities() in PHP before rendering user data
- Deploy Content Security Policy (CSP) headers to mitigate the impact of XSS attacks
- Review and audit all user profile data currently stored in the database for malicious content
- Consider temporarily restricting profile editing functionality until patches are applied
Patch Information
As of the last NVD update on 2025-12-04, no official vendor patch has been released for this vulnerability. Organizations should monitor the official GitHub repository at https://github.com/Shridharshukl/Blood-Bank-Management-System for security updates.
In the absence of an official patch, organizations should implement the workarounds described below or consider alternative solutions if the application is critical to operations.
Workarounds
Until an official patch is available, implement the following mitigations:
Output Encoding: Modify the affected PHP files to properly encode user output. All instances where user profile data is rendered should use HTML entity encoding to prevent script execution.
Input Validation: Implement server-side input validation to reject or sanitize potentially dangerous characters in the rname, remail, rpassword, rphone, and rcity parameters.
Content Security Policy: Deploy CSP headers to restrict inline script execution:
# Apache configuration for CSP headers
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; object-src 'none';"
Web Application Firewall: Configure WAF rules to filter XSS payloads in HTTP requests targeting the vulnerable endpoints.
