CVE-2024-7223: Lot Reservation Management System SQLi Flaw

CVE-2024-7223 Overview

CVE-2024-7223 is a SQL injection vulnerability in SourceCodester Lot Reservation Management System 1.0, developed by oretnom23. The flaw resides in the /view_model.php script, where the id parameter is passed directly into a database query without proper sanitization. Attackers can exploit this issue remotely over the network with low privileges and no user interaction. A public proof-of-concept has been disclosed, increasing the risk of opportunistic exploitation against exposed instances. The vulnerability is tracked under VulDB identifier VDB-272803 and classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Remote attackers can manipulate SQL queries through the id parameter of /view_model.php, exposing application data and potentially enabling further compromise of the backend database.

Affected Products

• SourceCodester Lot Reservation Management System 1.0
• oretnom23 lot_reservation_management_system 1.0

Technical Details for CVE-2024-7223

Vulnerability Analysis

The vulnerability is a classic SQL injection in a PHP-based web application. The /view_model.php endpoint accepts an id parameter from the HTTP request and incorporates that value into a SQL statement without parameterized queries or input validation. An attacker can supply crafted SQL syntax in the id parameter to alter the query's logic.

Successful exploitation allows extracting arbitrary records from the underlying database, including reservation details, account information, and any other accessible tables. Depending on database privileges, attackers may also enumerate the schema, write files, or pivot to authentication bypass through UNION-based or boolean-based techniques. The publicly disclosed proof-of-concept hosted on GitHub Gist demonstrates the exploitation pattern.

Root Cause

The root cause is unsanitized user input flowing directly into a SQL query string. The application concatenates the id value into its query rather than using prepared statements with bound parameters. This pattern enables attacker-controlled data to be interpreted as SQL code by the database engine.

Attack Vector

Exploitation is remote and requires only authenticated low-privilege access to the application, according to the CVSS 4.0 vector. An attacker sends an HTTP request to /view_model.php?id=<payload> containing SQL metacharacters such as single quotes, UNION SELECT constructs, or time-based blind injection primitives. No user interaction is required, and the attack can be automated with standard tooling such as sqlmap.

The vulnerability is described in prose only because no verified exploitation code is included here. Refer to the VulDB advisory for additional technical context.

Detection Methods for CVE-2024-7223

Indicators of Compromise

• HTTP requests to /view_model.php containing SQL metacharacters such as ', --, /*, UNION, SELECT, or SLEEP( in the id parameter
• Web server logs showing unusually long or URL-encoded values for the id query string
• Database error messages referencing syntax issues correlated with requests to view_model.php
• Unexpected database query spikes or long-running queries originating from the application user

Detection Strategies

• Deploy web application firewall (WAF) rules that flag SQL injection patterns targeting the id parameter on /view_model.php
• Enable database query auditing to capture queries containing tautologies such as OR 1=1 or stacked statements
• Correlate web access logs with database logs to identify malformed queries traced back to a single client IP

Monitoring Recommendations

• Forward Apache, Nginx, and MySQL logs to a centralized SIEM and alert on SQL injection signatures against the affected URI
• Monitor outbound connections from the database host that could indicate post-exploitation data exfiltration
• Track repeated 500-level HTTP responses from /view_model.php, which often accompany blind injection probing

How to Mitigate CVE-2024-7223

Immediate Actions Required

• Restrict network access to the Lot Reservation Management System until a fix is applied, using firewall rules or VPN gating
• Audit /view_model.php and replace string concatenation with parameterized queries using PDO or mysqli prepared statements
• Apply input validation that enforces id as a numeric integer before it reaches database code
• Review recent web and database logs for evidence of prior exploitation attempts

Patch Information

No vendor patch is currently listed in the NVD record or VulDB advisory for CVE-2024-7223. Operators should treat the application as unmaintained for this issue and apply compensating controls. Monitor the VulDB entry and the SourceCodester project page for any future updates.

Workarounds

• Place the application behind a WAF such as ModSecurity with the OWASP Core Rule Set enabled in blocking mode
• Enforce least-privilege database accounts so the web application user cannot read sensitive tables or execute administrative SQL
• Implement a reverse proxy rule that rejects non-numeric values for the id parameter on /view_model.php
• Consider migrating to an actively maintained reservation management platform if production use is required

# Example ModSecurity rule to block non-numeric id values on /view_model.php
SecRule REQUEST_URI "@beginsWith /view_model.php" \
    "chain,deny,status:403,id:1007223,msg:'CVE-2024-7223 SQLi attempt'"
    SecRule ARGS:id "!@rx ^[0-9]+$" "t:none"
