CVE-2024-5894: Online Eyewear Shop SQLi Vulnerability

CVE-2024-5894 Overview

A critical SQL injection vulnerability has been identified in SourceCodester Online Eyewear Shop version 1.0. This vulnerability exists in the manage_product.php file, where improper handling of the id parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially enabling unauthorized access to the underlying database.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially escalate to further system compromise through the manage_product.php endpoint.

Technical Details for CVE-2024-5894

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from insufficient input validation in the product management functionality of the Online Eyewear Shop application. The manage_product.php file accepts user-supplied input through the id parameter without proper sanitization or parameterized queries. This allows attackers to inject arbitrary SQL statements that are executed directly against the backend database.

The vulnerability is network-accessible, meaning attackers do not require local access to the target system. No authentication or special privileges are needed to exploit this flaw, making it particularly dangerous for internet-facing deployments of this e-commerce application.

Root Cause

The root cause of this vulnerability is the direct concatenation of user-supplied input into SQL queries without proper input validation, sanitization, or the use of prepared statements. The id parameter in manage_product.php is passed directly to database queries, allowing attackers to manipulate the query logic through specially crafted input values.

Attack Vector

The attack is initiated remotely via HTTP requests to the vulnerable manage_product.php endpoint. An attacker crafts malicious input for the id parameter containing SQL injection payloads. When the application processes this input, the injected SQL commands are executed against the database, potentially allowing:

Data exfiltration from database tables
Modification or deletion of product and customer records
Authentication bypass
Potential privilege escalation depending on database permissions

The vulnerability allows manipulation of confidentiality, integrity, and availability of the application data. Attackers can craft payloads to enumerate database structure, extract sensitive customer information, or manipulate product listings.

Detection Methods for CVE-2024-5894

Indicators of Compromise

Unusual SQL error messages in application logs originating from manage_product.php
Anomalous database queries containing SQL keywords like UNION, SELECT, OR 1=1, DROP, or -- comment sequences in the id parameter
Unexpected access patterns to the manage_product.php endpoint with malformed or suspicious parameter values
Database audit logs showing unauthorized data access or extraction attempts

Detection Strategies

Deploy web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP parameters
Implement application-level logging to capture all requests to manage_product.php with full parameter values
Configure database query logging to identify anomalous or malformed SQL statements
Use intrusion detection systems (IDS) with signatures for common SQL injection patterns

Monitoring Recommendations

Monitor HTTP access logs for requests to manage_product.php containing special characters or SQL keywords in query parameters
Set up alerts for database errors that may indicate failed injection attempts
Review database access patterns for unusual query volumes or data extraction activities
Implement real-time monitoring for changes to critical database tables

How to Mitigate CVE-2024-5894

Immediate Actions Required

Take the affected Online Eyewear Shop application offline if it is exposed to the internet
Review access logs for evidence of exploitation attempts targeting manage_product.php
Implement input validation and prepared statements for all database queries as a code-level fix
Deploy a web application firewall (WAF) with SQL injection protection as a temporary measure

Patch Information

No official vendor patch has been released for this vulnerability. Organizations using SourceCodester Online Eyewear Shop 1.0 should implement manual code fixes or consider alternative solutions. Technical details about this vulnerability are available in the GitHub CVE Documentation and VulDB Entry #268138.

Workarounds

Implement parameterized queries (prepared statements) for all database operations in manage_product.php
Add strict input validation to ensure the id parameter only accepts numeric values
Deploy a WAF configured to block SQL injection patterns targeting the application
Restrict network access to the application to trusted IP ranges only
Apply principle of least privilege to database user accounts used by the application

bash

# Example: Apache mod_security rule to block SQL injection attempts
SecRule ARGS:id "@rx (?i)(\bunion\b|\bselect\b|\bor\b\s+\d+=\d+|--|;)" \
    "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Blocked',log"
