CVE-2024-4307: Ofofonobsdev Hubbank SQL Injection Vulnerability

CVE-2024-4307 Overview

CVE-2024-4307 is a SQL injection vulnerability in HubBank version 1.0.2 developed by ofofonobsdev. Authenticated attackers can inject malicious SQL through the id parameter across five distinct application endpoints. Successful exploitation allows extraction of arbitrary data from the underlying database, including account information and transaction records. The flaw maps to [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact
An authenticated attacker with low privileges can read and modify sensitive banking data by sending crafted SQL queries to multiple /accounts/*.php endpoints.

Technical Details for CVE-2024-4307

Vulnerability Analysis

HubBank 1.0.2 accepts the id GET parameter on five account-facing PHP scripts without proper sanitization or parameterization. The application concatenates the user-supplied value directly into SQL statements executed against the backend database. An authenticated attacker can therefore break out of the intended query context and append arbitrary SQL clauses.

Because the affected endpoints handle activities, deposits, cards, and wire transfers, the vulnerable queries touch high-value financial tables. Exploitation grants read access to any table the database user can reach, and permits modification of records when write operations are chained through UNION or stacked statements. The attack requires only a valid low-privilege session, which lowers the barrier for insiders or attackers who obtain credentials through phishing or reuse.

Root Cause

The root cause is missing input validation and lack of prepared statements in PHP database access code. The id parameter flows from the HTTP request into a dynamically constructed query string. Neither type coercion to integer nor parameter binding is applied before execution.

Attack Vector

The attack vector is network-based over HTTP or HTTPS. An attacker authenticates to HubBank with any valid account, then issues a request such as GET /accounts/view-deposit.php?id=1 UNION SELECT ... with SQL syntax appended to the numeric identifier. The database returns injected query results within the rendered page or through observable side channels such as timing and error responses.

No verified exploit code is publicly available. Refer to the INCIBE CERT Security Notice for the vendor coordination details.

Detection Methods for CVE-2024-4307

Indicators of Compromise

HTTP requests to /accounts/activities.php, /accounts/view-deposit.php, /accounts/view_cards.php, /accounts/wire-transfer.php, or /accounts/wiretransfer-pending.php where the id parameter contains non-numeric characters, quotes, or SQL keywords such as UNION, SELECT, SLEEP, or --.
Database error messages or unusually large response bodies returned from these endpoints.
Spikes in query latency on the HubBank database correlated with requests to the affected paths.

Detection Strategies

Deploy web application firewall rules that flag SQL metacharacters in the id parameter for the five affected endpoints.
Enable database query logging and alert on queries originating from HubBank that reference tables outside the expected scope of each page.
Correlate authenticated session identifiers with anomalous query patterns to identify compromised or malicious accounts.

Monitoring Recommendations

Forward web server access logs and database audit logs to a centralized analytics platform for correlation.
Alert on repeated 500-series responses from the affected PHP scripts, which often indicate injection probing.
Monitor outbound data volumes from the database server to detect bulk extraction attempts.

How to Mitigate CVE-2024-4307

Immediate Actions Required

Restrict network access to HubBank 1.0.2 instances until a fix is available, limiting reachability to trusted networks or VPN users.
Review authentication logs for suspicious low-privilege accounts and rotate credentials where compromise is suspected.
Audit the database for unauthorized reads or modifications on tables referenced by the affected endpoints.

Patch Information

No vendor patch is referenced in the enriched CVE data. Consult the INCIBE CERT Security Notice for vendor updates and remediation guidance.

Workarounds

Apply a reverse proxy or WAF rule that enforces strict integer validation on the id parameter for all five affected endpoints.
Modify the affected PHP scripts to cast $_GET['id'] to an integer before use, for example $id = (int)$_GET['id'];, and refactor queries to use prepared statements with bound parameters.
Restrict the database account used by HubBank to the minimum privileges required, removing rights to unrelated tables and schema objects.

bash

# Example nginx rule to reject non-numeric id values on affected endpoints
location ~ ^/accounts/(activities|view-deposit|view_cards|wire-transfer|wiretransfer-pending)\.php$ {
    if ($arg_id !~ ^[0-9]+$) {
        return 400;
    }
    include fastcgi_params;
    fastcgi_pass unix:/run/php/php-fpm.sock;
}
