CVE-2025-63527 Overview
A cross-site scripting (XSS) vulnerability exists in the Blood Bank Management System 1.0 within the updateprofile.php and hprofile.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 hname, hemail, hpassword, hphone, and hcity parameters, which are then executed in the victim's browser when the page is viewed.
This stored XSS vulnerability has been assigned a CVSS 3.1 score of 5.4 (Medium severity) with vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, indicating network-based attack vector with low attack complexity requiring low privileges and user interaction.
Critical Impact
Attackers can execute arbitrary JavaScript in the context of authenticated users' sessions, potentially leading to session hijacking, credential theft, and unauthorized actions within the Blood Bank Management System.

Technical Details for CVE-2025-63527
Vulnerability Analysis
The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting. The Blood Bank Management System version 1.0 contains multiple vulnerable parameters in its profile management functionality that fail to implement proper input validation and output encoding.
The EPSS (Exploit Prediction Scoring System) indicates a probability of 0.031% with an 8.437 percentile ranking, suggesting relatively low exploitation likelihood in the wild at this time. However, the availability of public exploit information increases the risk profile.
Root Cause
The root cause of this vulnerability stems from improper input handling in the updateprofile.php and hprofile.php PHP files. User-supplied data submitted through form fields is directly incorporated into the HTML response without proper sanitization or contextual output encoding. The vulnerable parameters include:
- hname - Hospital/User name field
- hemail - Email address field
- hpassword - Password field
- hphone - Phone number field
- hcity - City field
When these values are stored in the database and later rendered in the browser, any embedded JavaScript code executes within the victim's browser context.
Attack Vector
The attack vector is network-based (AV:N) and requires low privileges (PR:L) with user interaction (UI:R). An authenticated attacker with access to the profile update functionality can inject malicious scripts that will execute when other users (including administrators) view the affected profile pages.
The stored nature of this XSS vulnerability means the malicious payload persists in the application database, affecting all users who subsequently view the compromised data. This can lead to widespread session hijacking, phishing attacks, and data exfiltration.
Due to the changed scope (S:C) indicated in the CVSS vector, the vulnerability can impact resources beyond the vulnerable component, potentially affecting other users and system components.
Detection Methods for CVE-2025-63527
Indicators of Compromise
- Presence of JavaScript code or HTML tags in database fields for user profile data
- Unexpected <script> tags or event handlers (e.g., onerror, onload) in hname, hemail, hphone, or hcity fields
- Anomalous outbound requests from client browsers to external domains after viewing profile pages
- Browser console errors or unusual JavaScript execution when accessing profile management pages
Detection Strategies
Organizations running Blood Bank Management System 1.0 should implement the following detection strategies:
Web Application Firewall (WAF) Rules: Configure WAF rules to detect and block requests containing JavaScript payloads in form parameters targeting updateprofile.php and hprofile.php.
Database Monitoring: Implement database activity monitoring to flag insertions or updates containing potential XSS payloads such as <script>, javascript:, or HTML event handlers.
Log Analysis: Review web server access logs for suspicious POST requests to the vulnerable endpoints containing encoded or plaintext script injection attempts.
Content Security Policy Violations: Implement strict CSP headers and monitor for policy violation reports that may indicate XSS exploitation attempts.
Monitoring Recommendations
Security teams should establish continuous monitoring for this vulnerability:
- Enable detailed logging for all profile update operations
- Monitor for unusual patterns in profile field content lengths or character sets
- Set up alerts for CSP violation reports originating from affected pages
- Implement real-time scanning of user-submitted content for potential XSS vectors
How to Mitigate CVE-2025-63527
Immediate Actions Required
- Restrict access to profile management functionality to trusted users only
- Implement Web Application Firewall (WAF) rules to filter XSS payloads in affected parameters
- Review and sanitize existing database entries for malicious content in profile fields
- Deploy Content Security Policy (CSP) headers to mitigate XSS impact
- Consider temporarily disabling the profile update functionality until patches are available
Patch Information
As of the last NVD update on 2025-12-02, no official vendor patch has been released for this vulnerability. Organizations should monitor the project's GitHub repository at https://github.com/Shridharshukl/Blood-Bank-Management-System for security updates.

Workarounds
In the absence of an official patch, organizations can implement the following workarounds:
Input Validation and Output Encoding: Modify the updateprofile.php and hprofile.php files to implement proper input validation using PHP's filter_input() function and output encoding using htmlspecialchars() with ENT_QUOTES flag for all user-supplied data.
Server-Side Sanitization: Implement server-side sanitization using established libraries to strip or encode potentially dangerous characters before storing data in the database.
Content Security Policy: Deploy restrictive CSP headers to prevent inline script execution:
Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'
Access Control: Implement additional access controls to limit who can modify profile information and ensure proper session validation on all profile-related endpoints.
