CVE-2025-63527: Critical XSS Threatens Blood Bank Management System 1.0 Users

Overview

CVE-2025-63527 is a high-severity cross-site scripting (XSS) vulnerability discovered in the Blood Bank Management System version 1.0. This vulnerability allows attackers to inject malicious JavaScript code into user profiles, potentially compromising user accounts and data. The vulnerability is present in the updateprofile.php and hprofile.php components.

Technical Details

The Blood Bank Management System 1.0 fails to properly sanitize or encode user-supplied input within the updateprofile.php and hprofile.php files. Specifically, the application is vulnerable to stored XSS through the following parameters:

  • hname
  • hemail
  • hpassword
  • hphone
  • hcity

An attacker can inject malicious JavaScript payloads into these parameters. When a user views the affected profile page, the injected script will execute in their browser, potentially allowing the attacker to steal cookies, redirect the user to a malicious website, or perform other actions on their behalf.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. CVE-2025-63527 has the following characteristics:

  • Severity: HIGH
  • CVSS Score: 8.5

A CVSS score of 8.5 indicates a high-severity vulnerability, meaning it is likely to be exploited and can have significant consequences.

Possible Impact

The successful exploitation of this XSS vulnerability can have several significant impacts:

  • Account Compromise: Attackers can steal user session cookies, gaining unauthorized access to user accounts.
  • Data Theft: Sensitive data stored within the application, such as blood type information or contact details, could be stolen.
  • Malicious Redirects: Users could be redirected to phishing websites designed to steal their credentials or install malware.
  • Defacement: The application’s user interface could be defaced, damaging the reputation of the blood bank.

Mitigation & Patch Steps

To mitigate this vulnerability, the following steps are recommended:

  1. Input Sanitization: Implement proper input sanitization and validation on all user-supplied data, especially for the hname, hemail, hpassword, hphone, and hcity parameters. Use appropriate encoding functions (e.g., HTML entity encoding) before rendering the data in the web page.
  2. Output Encoding: Encode data before displaying it in the HTML output to prevent the browser from interpreting it as executable code.
  3. Upgrade: Upgrade to a patched version of the Blood Bank Management System as soon as it becomes available. Contact the vendor or the project maintainers for an official patch.
  4. Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to filter out malicious requests and protect against XSS attacks.
