CVE-2024-9316: Blood Bank System SQL Injection Flaw

CVE-2024-9316 Overview

CVE-2024-9316 is a SQL injection vulnerability in code-projects Blood Bank Management System 1.0. The flaw resides in the /admin/blood/update/B+.php script, where the Bloodname parameter is passed to a database query without proper sanitization. Attackers can manipulate this argument to inject arbitrary SQL statements against the backend database.

The issue is remotely exploitable and requires only low-privileged authentication. Public exploit details have been disclosed, increasing the likelihood of opportunistic scanning and abuse. The vulnerability is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact
Authenticated remote attackers can inject SQL to read, modify, or delete blood bank records, including donor and patient data stored in the application database.

Technical Details for CVE-2024-9316

Vulnerability Analysis

The vulnerability affects the administrative blood update workflow of the Blood Bank Management System. The PHP endpoint at /admin/blood/update/B+.php accepts a Bloodname request parameter and concatenates it directly into a SQL query. Because the value is not parameterized or escaped, attackers can break out of the intended string context and append additional SQL clauses.

Exploitation requires network access to the admin interface and a valid low-privileged session. Once authenticated, an attacker submits a crafted Bloodname value containing SQL metacharacters. The public disclosure includes proof-of-concept payloads hosted on the GitHub CVE Documentation repository, lowering the barrier for reproduction.

The EPSS probability is approximately 0.417% (percentile 34.2), reflecting moderate but non-trivial exploitation likelihood given the small deployment footprint of this application.

Root Cause

The root cause is improper neutralization of user-controlled input inside a SQL query [CWE-89]. The Bloodname parameter reaches the database driver as raw string data with no prepared statement binding, allowing attacker-supplied syntax to alter the query's logic.

Attack Vector

The attack vector is network-based over HTTP or HTTPS against the application's admin panel. An authenticated attacker sends a modified request to /admin/blood/update/B+.php with a malicious Bloodname value. Successful exploitation can enumerate database schema, dump records such as donor identities and blood inventory, and modify or delete entries. See the published proof of concept in the VulDB entry #278820 for reproduction details.

Detection Methods for CVE-2024-9316

Indicators of Compromise

HTTP requests to /admin/blood/update/B+.php containing SQL metacharacters in the Bloodname parameter, such as single quotes, UNION, SELECT, --, or OR 1=1.
Web server or PHP error logs referencing SQL syntax errors originating from the blood update endpoint.
Unexpected changes, additions, or deletions in blood inventory or donor tables.
Outbound database connections or data exports initiated from the application host that do not match baseline behavior.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect POST and GET parameters submitted to /admin/blood/update/B+.php for SQL injection patterns.
Enable database query logging and alert on queries against blood or donor tables that contain unbalanced quotes or stacked statements.
Correlate admin session activity with anomalous query volume or response sizes indicating data exfiltration attempts.

Monitoring Recommendations

Monitor authentication logs for brute-force attempts against the admin login preceding requests to the vulnerable endpoint.
Alert on repeated 500-series HTTP responses from B+.php, which often indicate injection probing.
Track file integrity of PHP source files in the /admin/blood/ directory to detect webshell drops following successful exploitation.

How to Mitigate CVE-2024-9316

Immediate Actions Required

Restrict network access to the Blood Bank Management System admin interface using IP allow-lists or a VPN.
Rotate all administrator credentials and audit existing admin accounts for unauthorized additions.
Review database contents for tampering and back up known-good data before further remediation.
Deploy WAF signatures to block SQL injection payloads targeting the Bloodname parameter.

Patch Information

No vendor-supplied patch is listed in available advisories at the time of publication. Refer to the vendor site at code-projects.org for updated releases. Organizations running this software should consider migrating to a maintained blood bank management platform if a fix does not become available.

Workarounds

Disable or remove the /admin/blood/update/B+.php endpoint if the update workflow is not required.
Introduce a reverse proxy that enforces strict input validation on the Bloodname parameter, rejecting non-alphanumeric characters.
Apply least-privilege database credentials to the application account, removing DDL and cross-table SELECT permissions where possible.
Enable prepared statements in a forked or patched copy of the affected PHP script if in-house maintenance is available.
