CVE-2024-4308: Ofofonobsdev HubBank SQL Injection Flaw

CVE-2024-4308 Overview

CVE-2024-4308 is a SQL injection vulnerability in HubBank version 1.0.2 developed by ofofonobsdev. The flaw resides in multiple administrative endpoints where the id parameter is passed directly to the database layer without proper sanitization. An authenticated attacker can send crafted SQL statements through these endpoints and extract data stored in the backend database. The vulnerability is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact
Attackers with low-privileged access can extract sensitive banking data including user records, loan transactions, deposits, and payment card information stored by HubBank.

Affected Products

ofofonobsdev HubBank 1.0.2
HubBank administrative interface endpoints processing the id parameter
Backend database components accessed through the vulnerable endpoints

Technical Details for CVE-2024-4308

Vulnerability Analysis

The vulnerability exists in several PHP scripts within the HubBank administrative interface. Each affected endpoint accepts an id parameter through the query string and concatenates it into a SQL statement without parameterization or input validation. This allows an authenticated attacker to break out of the intended query context and inject arbitrary SQL syntax.

The affected endpoints include /admin/view_users.php, /admin/viewloan-trans.php, /admin/view-deposit.php, /admin/view-domtrans.php, /admin/delete_cards.php, and /admin/view_cards.php. Because HubBank is a banking application, exploited queries can return records containing account information, loan transactions, deposit history, and card data.

Root Cause

The root cause is the absence of prepared statements or parameterized queries in the affected PHP handlers. User-controlled input from the id GET parameter is placed directly into SQL statements, giving the attacker full control over the query structure passed to the database engine.

Attack Vector

Exploitation requires network access to the HubBank administrative interface and low-privileged authenticated access. An attacker appends SQL syntax such as UNION SELECT payloads or boolean-based conditions to the id parameter of any vulnerable endpoint. The database returns injected query results either in the HTTP response body or through inferable timing and error signals. See the INCIBE Security Notice on HubBank Vulnerabilities for additional technical context.

Detection Methods for CVE-2024-4308

Indicators of Compromise

HTTP requests to /admin/view_users.php, /admin/viewloan-trans.php, /admin/view-deposit.php, /admin/view-domtrans.php, /admin/delete_cards.php, or /admin/view_cards.php containing SQL keywords such as UNION, SELECT, SLEEP, or -- in the id parameter.
Database error messages returned in HTTP responses referencing SQL syntax or column mismatches.
Unusually long or encoded id parameter values in web server access logs.

Detection Strategies

Deploy web application firewall rules that inspect the id query parameter for SQL metacharacters and known injection patterns.
Enable database query logging and alert on unexpected query structures originating from HubBank service accounts.
Correlate authenticated administrative sessions with anomalous query volume or response sizes.

Monitoring Recommendations

Monitor HubBank web server logs for repeated requests to the vulnerable endpoints from a single session.
Track outbound data volume from the HubBank database server to detect bulk record exfiltration.
Alert on administrative account logins from unexpected geographies or IP ranges preceding endpoint access.

How to Mitigate CVE-2024-4308

Immediate Actions Required

Restrict access to the /admin/ path using network controls or authentication proxies until a patched release is available.
Rotate credentials for any administrative accounts that may have accessed the vulnerable endpoints.
Audit the HubBank database for signs of unauthorized read activity against user, card, deposit, and loan tables.

Patch Information

No vendor patch has been published in the referenced advisories at the time of NVD publication. Consult the INCIBE Security Notice on HubBank Vulnerabilities for updates from ofofonobsdev regarding remediation availability.

Workarounds

Place a web application firewall in front of HubBank with signatures blocking SQL injection payloads targeting the id parameter.
Enforce least-privilege database accounts so the HubBank web tier cannot read sensitive tables it does not require.
Disable or firewall the vulnerable administrative endpoints if they are not actively required in the deployment.
