Blood Bank Management System SQL Injection Allows Authentication Bypass

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2025-63531

The vulnerability exists in a web-based management system login component. As a Blood Bank Management System, such applications are typically deployed as web-accessible portals intended for users to authenticate and access the system over a network, making public-facing or external-facing exposure a common and expected deployment pattern.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory details a critical vulnerability in the Blood Bank Management System that could allow unauthorized access. The issue stems from how the system handles login credentials, where an attacker could potentially bypass authentication mechanisms. The main concern is to confirm if this specific system is in use and accessible externally.

  • System login can be bypassed.
  • Critical access risk if system is exposed.
  • Confirm relevance and external exposure.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by sending specially crafted input to the login page of the Blood Bank Management System. Because the application does not properly validate the data submitted in the `remail` and `rpassword` fields, an attacker can insert malicious SQL code. This allows them to bypass the intended authentication checks and gain unauthorized access to the system.

  • No authentication required to access.
  • Manipulate login fields to inject SQL.
  • Unauthorized system access and data compromise.

Live Threat

Current exploitation, exposure, and threat context

A SQL injection vulnerability in the Blood Bank Management System's login component could allow an unauthenticated attacker to bypass authentication and access the system. This occurs when user input is not properly sanitized in SQL queries, enabling the injection of arbitrary SQL code.

  • System and user data at risk.
  • Via manipulated login fields.
  • Unauthorized system access.

Operational Fix

Recommended remediation, mitigation, and detection steps

Application owners and infrastructure teams are likely responsible for addressing this SQL injection vulnerability in the Blood Bank Management System. The first practical step is to identify all instances of the affected application, confirm their reachability and business criticality, and then assign ownership for remediation planning based on assessed risk.

  • Identify application instances and owners.
  • Verify external reachability and criticality.
  • Plan remediation based on risk.

Frequently asked questions

What is the Blood Bank Management System?

It is a web-based software application designed by shridharshukl to organize blood donation records, donor information, and inventory management. Organizations typically deploy this system as a portal to allow staff to log in and manage data over a network.

How does CVE-2025-63531 work?

This vulnerability is a SQL injection, classified as CWE-89. It happens when the software fails to clean user input before processing it in a database query. In this case, the login fields do not safely handle data, which allows an attacker to enter malicious commands instead of a username or password.

Do I need special access to trigger this bug?

No, you do not need prior authentication. The vulnerability exists in the receiverLogin.php page, which is publicly accessible to anyone visiting the site. Simply submitting crafted, non-standard text into the email or password fields is enough to potentially bypass security controls.

Why should I care about this vulnerability?

According to Halo Surface Signal, this software is often deployed as a web-accessible portal. Because the flaw exists in the login component, any instance that is reachable over the internet is at higher risk of unauthorized access, potentially exposing sensitive blood bank data to external attackers.

What is the first step to address this?

Start by auditing your network to identify all running instances of this specific management system. Once found, verify if they are accessible from the internet and evaluate their business importance. Use this information to assign ownership and begin a plan to restrict access or update the software.
