CVE-2024-7505: Rainniar Bike Delivery System SQLi Flaw

CVE-2024-7505 Overview

CVE-2024-7505 is a SQL Injection vulnerability affecting the itsourcecode Bike Delivery System version 1.0. The vulnerability exists in the contact_us_action.php file, where improper handling of the name parameter allows attackers to inject malicious SQL statements. This weakness enables unauthorized database access and manipulation through remotely exploitable network-based attacks.

Critical Impact

Attackers can exploit this SQL Injection vulnerability to bypass authentication, extract sensitive data from the database, modify or delete records, and potentially gain unauthorized access to the underlying system through database command execution.

Affected Products

• Rainniar Bike Delivery System 1.0
• itsourcecode Bike Delivery System contact_us_action.php component

Discovery Timeline

• August 6, 2024 - CVE-2024-7505 published to NVD

Technical Details for CVE-2024-7505

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs in the contact_us_action.php file of the Bike Delivery System application. The vulnerable code fails to properly sanitize or parameterize user input from the name parameter before incorporating it into SQL queries. This allows attackers to craft malicious input that alters the intended SQL statement logic, enabling unauthorized database operations.

The vulnerability is remotely exploitable without requiring authentication or user interaction, making it accessible to any attacker with network access to the application. The public disclosure of this exploit significantly increases the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries or prepared statements in the contact_us_action.php file. When user-supplied data from the name parameter is directly concatenated into SQL query strings without proper sanitization or escaping, it creates an injection point that attackers can leverage to execute arbitrary SQL commands.

Attack Vector

The attack can be launched remotely over the network against any exposed instance of the Bike Delivery System. An attacker can submit specially crafted input through the name parameter in requests to contact_us_action.php. By injecting SQL metacharacters and statements, the attacker can manipulate database queries to:

• Extract sensitive user data and credentials
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially execute system commands if database permissions allow

The vulnerability mechanism involves manipulating the name parameter to inject SQL syntax that breaks out of the intended query structure. For detailed technical analysis, refer to the GitHub Issue Discussion and VulDB entry #273648.

Detection Methods for CVE-2024-7505

Indicators of Compromise

• Unusual or malformed requests to contact_us_action.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or data extraction patterns in database audit logs
• Anomalous traffic patterns targeting the contact form endpoint

Detection Strategies

• Deploy web application firewalls (WAF) configured with SQL Injection detection rules targeting the contact_us_action.php endpoint
• Implement application-layer logging to capture and analyze all requests to vulnerable PHP files
• Monitor database query logs for suspicious patterns including UNION-based, error-based, or time-based blind injection attempts
• Use intrusion detection systems with signatures for common SQL Injection payloads

Monitoring Recommendations

• Enable detailed logging for all web application requests, particularly those involving user input parameters
• Configure database audit logging to track all queries executed against the application database
• Set up alerts for high volumes of requests to contact_us_action.php or requests containing known SQLi patterns
• Regularly review access logs for reconnaissance activity targeting form endpoints

How to Mitigate CVE-2024-7505

Immediate Actions Required

• Restrict network access to the Bike Delivery System application to trusted networks only
• Implement a web application firewall with SQL Injection protection rules
• Consider taking the application offline until proper remediation can be applied
• Audit database logs for evidence of prior exploitation

Patch Information

No official vendor patch is currently available for this vulnerability. The affected software, Rainniar Bike Delivery System 1.0, should be considered insecure until the developer releases a security update. Organizations using this software should monitor VulDB and vendor channels for patch announcements.

Workarounds

• Implement prepared statements and parameterized queries in the contact_us_action.php file to properly handle user input
• Deploy input validation to sanitize the name parameter, rejecting any input containing SQL metacharacters
• Use a web application firewall to filter malicious requests before they reach the application
• Restrict database user permissions to the minimum required for application functionality
