CVE-2024-5983: Online Book Store Project SQLi Vulnerability

CVE-2024-5983 Overview

A critical SQL injection vulnerability has been identified in itsourcecode Online Bookstore version 1.0. The vulnerability exists in the bookPerPub.php file, where improper handling of the pubid argument allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data manipulation, and information disclosure.

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 vulnerable bookPerPub.php endpoint.

Affected Products

• itsourcecode Online Book Store Project 1.0
• Applications using the vulnerable bookPerPub.php component
• Systems running unpatched versions of itsourcecode online_book_store_project

Technical Details for CVE-2024-5983

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) affects the bookPerPub.php file within the itsourcecode Online Bookstore application. The vulnerability stems from insufficient input validation on the pubid parameter, which is directly incorporated into SQL queries without proper sanitization or parameterization. When user-controlled input reaches the database query without adequate filtering, attackers can manipulate the query logic to access unauthorized data or perform destructive operations.

The network-accessible nature of this vulnerability means that any attacker with network access to the application can attempt exploitation without requiring authentication or user interaction. The exploit has been publicly disclosed, increasing the risk of widespread exploitation attempts against vulnerable installations.

Root Cause

The root cause of CVE-2024-5983 is improper input validation in the bookPerPub.php file. The pubid parameter is passed directly into SQL queries without being sanitized, escaped, or processed through prepared statements. This classic SQL injection pattern occurs when dynamic SQL queries are constructed using string concatenation with untrusted user input, rather than using parameterized queries or stored procedures with proper input binding.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the pubid parameter when accessing the bookPerPub.php endpoint. The malicious input is then processed by the application and executed against the backend database, allowing the attacker to:

• Extract sensitive information from the database
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially escalate to operating system command execution depending on database configuration

The vulnerability is accessible through direct HTTP requests to the affected endpoint, making it trivial to exploit using common tools and techniques. Technical details and proof-of-concept information are available through the GitHub Issue Discussion.

Detection Methods for CVE-2024-5983

Indicators of Compromise

• Unusual or malformed HTTP requests to bookPerPub.php containing SQL syntax in the pubid parameter
• Database error messages appearing in application logs or responses indicating SQL syntax errors
• Unexpected database queries containing UNION, SELECT, OR, AND operators with unusual patterns
• Access logs showing repeated requests to bookPerPub.php with varying pubid values containing special characters

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests
• Implement database activity monitoring to identify anomalous query patterns or unauthorized data access
• Configure application logging to capture and alert on SQL errors or exceptions
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor access logs for requests to bookPerPub.php containing suspicious characters such as single quotes, double dashes, or SQL keywords
• Set up alerts for database connection errors or authentication failures that may indicate injection attempts
• Review database audit logs for queries executed against sensitive tables
• Implement real-time alerting for any detected SQL injection patterns in network traffic

How to Mitigate CVE-2024-5983

Immediate Actions Required

• Immediately restrict access to bookPerPub.php if the application is not actively required
• Implement input validation to sanitize the pubid parameter before processing
• Deploy Web Application Firewall rules to block common SQL injection patterns
• Review application logs for evidence of exploitation attempts
• Consider taking the affected application offline until remediation is complete

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations using itsourcecode Online Bookstore 1.0 should contact the vendor or implement the workarounds described below. Additional technical details and community discussion are available through the VulDB entry.

Workarounds

• Implement prepared statements or parameterized queries in the bookPerPub.php file to prevent SQL injection
• Add input validation to restrict the pubid parameter to expected numeric values only
• Deploy a Web Application Firewall (WAF) in front of the application to filter malicious requests
• Restrict database user privileges to minimum required permissions to limit impact of successful exploitation
• Consider using an application-level SQL injection filter as a temporary mitigation

# Example Apache .htaccess rule to block common SQL injection patterns
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (\%27)|(\')|(\-\-)|(\%23)|(#) [NC,OR]
    RewriteCond %{QUERY_STRING} (union|select|insert|drop|delete|update|cast|create|char|convert|alter|declare|order|script|set|md5|benchmark|encode) [NC]
    RewriteRule ^bookPerPub\.php$ - [F,L]
