CVE-2024-33969: Janobe Credit Card SQLi Vulnerability

CVE-2024-33969 Overview

CVE-2024-33969 is a SQL injection vulnerability affecting multiple Janobe products version 1.0, including PayPal, Credit Card, and Debit Card Payment modules. The flaw resides in the id parameter of the /AttendanceMonitoring/department/index.php endpoint. An unauthenticated attacker can send a crafted query to the server and extract data stored in the backend database. The issue is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Unauthenticated remote attackers can exfiltrate the contents of the application database through a single HTTP request.

Affected Products

• Janobe Credit Card 1.0
• Janobe Debit Card Payment 1.0
• Janobe PayPal 1.0
• Janobe School Attendance Monitoring System 1.0
• Janobe School Event Management System 1.0

Technical Details for CVE-2024-33969

Vulnerability Analysis

The vulnerability is a classic SQL injection in the id request parameter handled by /AttendanceMonitoring/department/index.php. The application concatenates the user-supplied id value directly into a SQL query without parameterization or input sanitization. An attacker can append SQL operators such as UNION SELECT, boolean conditions, or time-based payloads to manipulate the executed query.

Because the endpoint requires no authentication, exploitation is reachable from any network position that can deliver HTTP requests to the application. Successful injection allows full read access to database tables, exposing customer data, payment-related records, and credentials when stored in the same instance.

Root Cause

The root cause is the absence of prepared statements or input validation for the id parameter. The application trusts client-controlled input and inlines it into a SQL statement. This pattern, classified as CWE-89, is well-documented and addressable through parameterized queries.

Attack Vector

An attacker submits a crafted GET or POST request targeting /AttendanceMonitoring/department/index.php?id=<payload>. The payload modifies the underlying query to extract arbitrary table contents. Tools such as sqlmap automate detection and exploitation against the parameter. No user interaction or prior privileges are required, and exploitation produces measurable database responses.

No verified public exploit code is available. See the INCIBE CERT Vulnerability Notice for additional technical context.

Detection Methods for CVE-2024-33969

Indicators of Compromise

• HTTP requests to /AttendanceMonitoring/department/index.php containing SQL meta-characters such as ', ", --, UNION, SELECT, SLEEP(, or BENCHMARK( in the id parameter.
• Unexpected outbound traffic or anomalous response sizes from the web server hosting the Janobe application.
• Database error strings (for example, SQLSTATE, mysql_fetch) appearing in HTTP responses captured by web proxies.

Detection Strategies

• Inspect web server access logs for repeated requests to /AttendanceMonitoring/department/index.php with encoded SQL syntax or abnormal id values.
• Deploy web application firewall (WAF) signatures targeting SQL injection patterns against the affected URI.
• Correlate web request anomalies with database query logs to identify queries that deviate from normal application behavior.

Monitoring Recommendations

• Enable verbose access logging on the web server fronting the Janobe application and forward logs to a centralized analytics platform.
• Alert on HTTP 500 responses or repeated 200 responses with unusually large payload sizes from the vulnerable endpoint.
• Monitor authentication tables and sensitive data tables for read patterns inconsistent with normal application workflows.

How to Mitigate CVE-2024-33969

Immediate Actions Required

• Restrict network access to the affected Janobe applications until a vendor fix is verified, allowing only trusted source addresses.
• Place a WAF in blocking mode in front of /AttendanceMonitoring/department/index.php with SQL injection rule sets enabled.
• Review web and database logs for evidence of prior exploitation and rotate any credentials that may have been exposed.

Patch Information

No vendor advisory or patch URL is listed in the NVD record at the time of publication. Operators should monitor the INCIBE CERT Vulnerability Notice and the Janobe project for an official fix. Until a patch is available, treat the affected version 1.0 components as vulnerable in production.

Workarounds

• Refactor the application to use parameterized queries or prepared statements for the id parameter and other database inputs.
• Apply server-side input validation that rejects non-numeric values for id before the value reaches the data access layer.
• Run the application database account with least privilege so that injection cannot reach administrative tables or stored procedures.

# Example ModSecurity rule blocking SQLi patterns on the vulnerable endpoint
