CVE-2025-2039: Blood Bank Management System SQLi Flaw

CVE-2025-2039 Overview

CVE-2025-2039 is a SQL injection vulnerability in code-projects Blood Bank Management System 1.0. The flaw resides in the /admin/delete_members.php script, where the member_id parameter is passed directly into a database query without sanitization. Remote authenticated attackers can manipulate this parameter to inject arbitrary SQL statements. The exploit details have been disclosed publicly, increasing the likelihood of opportunistic abuse against exposed installations. The weakness maps to [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Authenticated attackers can read, modify, or delete records in the blood bank database, including donor and member information, by injecting SQL through the member_id parameter.

Affected Products

code-projects Blood Bank Management System 1.0
Deployments using the vulnerable /admin/delete_members.php endpoint
Installations exposing the admin interface to untrusted networks

Technical Details for CVE-2025-2039

Vulnerability Analysis

The vulnerability exists in the administrative member deletion workflow of Blood Bank Management System 1.0. The /admin/delete_members.php endpoint accepts the member_id argument from the HTTP request and concatenates it into a SQL DELETE statement. Because the application does not validate or parameterize this input, attackers can append additional SQL syntax. Successful injection can disclose database contents, alter authorization records, or destroy stored medical data.

The attack requires network access to the admin endpoint and an authenticated session with administrative privileges. Public disclosure of the exploit lowers the technical barrier for reproduction.

Root Cause

The root cause is direct concatenation of untrusted input into a SQL statement. The PHP code servicing delete_members.php does not use prepared statements or apply type casting on the member_id value. Any string supplied for this parameter reaches the database engine intact.

Attack Vector

An attacker with access to the admin panel sends a crafted HTTP request to /admin/delete_members.php with a malicious member_id value. Payloads such as boolean-based, UNION-based, or time-based blind injection techniques apply, depending on the backend MySQL configuration. The attack is fully remote and does not require user interaction beyond the initial authenticated session.

The vulnerability mechanism is described in the GitHub exploit documentation and tracked in VulDB entry 298782. No verified proof-of-concept code is reproduced here.

Detection Methods for CVE-2025-2039

Indicators of Compromise

HTTP requests to /admin/delete_members.php containing SQL metacharacters such as ', --, UNION, SLEEP(, or OR 1=1 in the member_id parameter
Unusually long or URL-encoded values for member_id in web server access logs
Database error messages referencing delete_members.php in PHP error logs
Unexpected deletions or modifications of records in the members table

Detection Strategies

Inspect web server logs for parameter tampering patterns targeting member_id
Deploy web application firewall rules that flag SQL keywords in admin endpoint parameters
Correlate authentication events with subsequent administrative actions to identify session abuse
Enable MySQL general query logging temporarily to capture injected statements during incident response

Monitoring Recommendations

Alert on repeated 500 errors returned by /admin/delete_members.php
Monitor outbound database traffic for anomalous query volume from the PHP application user
Track changes to administrative tables and donor records with database-level auditing

How to Mitigate CVE-2025-2039

Immediate Actions Required

Restrict network access to the /admin/ directory using IP allowlisting or VPN
Rotate administrator credentials and invalidate active admin sessions
Audit the members table and related records for unauthorized modifications
Deploy a WAF rule that blocks SQL metacharacters in the member_id parameter

Patch Information

No official vendor patch is listed in the available references for Blood Bank Management System 1.0. Organizations running this application should review the code-projects website for updates and consider migrating to a maintained alternative. Until a vendor fix is published, apply the workarounds below.

Workarounds

Modify delete_members.php to use prepared statements with bound parameters via PDO or mysqli
Cast member_id to an integer before using it in any SQL statement
Remove or disable the delete_members.php endpoint if member deletion is not required
Place the application behind authenticated reverse-proxy access controls

bash

# Example PHP remediation pattern using PDO prepared statements
$stmt = $pdo->prepare('DELETE FROM members WHERE member_id = :id');
$stmt->bindValue(':id', (int) $_REQUEST['member_id'], PDO::PARAM_INT);
$stmt->execute();
