CVE-2024-4309 Overview
CVE-2024-4309 is a SQL injection vulnerability in HubBank version 1.0.2 developed by ofofonobsdev. The flaw affects multiple /user/ endpoints, including transaction.php, credit-debit_transaction.php, view_transaction.php, and viewloantrans.php. An authenticated attacker can supply a crafted id parameter to manipulate backend SQL queries and extract data from the database. The vulnerability is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
Critical Impact
Successful exploitation allows attackers to read and modify sensitive financial records stored in the HubBank database, including transaction and loan data.

Technical Details for CVE-2024-4309
Vulnerability Analysis
HubBank 1.0.2 exposes several PHP endpoints under the /user/ path that accept an id query parameter. The application concatenates this parameter directly into SQL statements without parameterization or input sanitization. Attackers with a valid low-privilege session can inject SQL fragments through the id value.
The affected endpoints handle financial data, including transaction histories and loan records. Injection at these points exposes sensitive banking information and allows tampering with stored records. The INCIBE Security Notice documents multiple related flaws in the same application.
Root Cause
The root cause is missing input validation and lack of prepared statements in HubBank's database query logic. The vulnerable PHP files pass user-controlled id values into SQL queries without escaping or type enforcement. This classic SQL injection pattern is categorized under [CWE-89].
Attack Vector
Exploitation requires network access to the HubBank application and a low-privilege authenticated user session. Attackers craft HTTP requests such as /user/transaction.php?id=1' UNION SELECT ...-- to append arbitrary SQL clauses to the original query. The database engine executes the injected payload, returning attacker-controlled result sets. No user interaction is required beyond the attacker's own session.
Because the vulnerable parameters appear across four separate endpoints, defenders must treat each as an independent injection point. The vulnerability primarily impacts confidentiality and integrity of stored data.
Detection Methods for CVE-2024-4309
Indicators of Compromise
- Web server access logs containing SQL metacharacters (', --, UNION, SELECT, SLEEP) in the id parameter of /user/transaction.php, /user/credit-debit_transaction.php, /user/view_transaction.php, or /user/viewloantrans.php
- Anomalous database errors returned in HTTP responses from HubBank endpoints
- Unexpected outbound queries or bulk record retrieval from the HubBank database user
Detection Strategies
- Deploy a web application firewall (WAF) with signatures for SQL injection patterns targeting the id parameter
- Enable database query logging and alert on queries containing unbalanced quotes or UNION-based patterns originating from HubBank
- Correlate authentication events with request bursts against the affected /user/ endpoints
Monitoring Recommendations
- Monitor authenticated user sessions for unusual request volume against transaction and loan endpoints
- Track HTTP 500 responses from HubBank pages, which often signal failed injection attempts
- Review database audit logs for SELECT statements returning more rows than the application UI would normally request
How to Mitigate CVE-2024-4309
Immediate Actions Required
- Restrict network access to HubBank 1.0.2 until a vendor patch is available
- Enforce WAF rules that block SQL metacharacters in the id parameter of the four affected endpoints
- Rotate database credentials and audit user accounts with access to HubBank
- Review database logs for signs of prior data extraction attempts
Patch Information
No vendor patch is listed in the NVD entry for CVE-2024-4309 at the time of publication. Consult the INCIBE Security Notice for the latest advisory information and contact the HubBank maintainer for remediation guidance.
Workarounds
- Place HubBank behind a reverse proxy that validates the id parameter as a strict integer
- Apply least-privilege permissions to the HubBank database account, removing rights to unrelated tables
- Disable or gate the affected /user/ endpoints if they are not required in production
# Example WAF rule (ModSecurity) blocking SQLi patterns on HubBank id parameter
SecRule REQUEST_URI "@rx /user/(transaction|credit-debit_transaction|view_transaction|viewloantrans)\.php" \
"chain,phase:2,deny,status:403,id:1004309,msg:'CVE-2024-4309 HubBank SQLi attempt'"
