CVE-2024-7222: Lot Reservation Management System SQLi Flaw

CVE-2024-7222 Overview

CVE-2024-7222 is a SQL injection vulnerability in SourceCodester Lot Reservation Management System 1.0, developed by oretnom23. The flaw resides in an unknown function within /home.php, where the type parameter is passed unsanitized into a SQL query. Attackers with low-privilege network access can manipulate this argument to inject arbitrary SQL statements. The exploit has been publicly disclosed under VulDB identifier VDB-272802, increasing the risk of opportunistic attacks against exposed installations. The weakness is tracked under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact

Remote attackers can read, modify, or delete database records by injecting SQL through the type parameter in /home.php, with public exploit code already available.

Technical Details for CVE-2024-7222

Vulnerability Analysis

The vulnerability is a classic SQL injection in the /home.php endpoint of the Lot Reservation Management System. The application accepts user-supplied input via the type request parameter and concatenates it directly into a backend SQL query without parameterization or input validation. An attacker can issue crafted HTTP requests to alter query logic, extract arbitrary data from the database, or manipulate stored records. Because the application is a PHP/MySQL web platform intended for property reservation workflows, the database typically contains reservation records, client details, and administrative credentials. Exploitation requires network access and a low-privilege account, but no user interaction is needed.

Root Cause

The root cause is the use of dynamic SQL string concatenation with unsanitized input from the type HTTP parameter. The application fails to apply prepared statements, parameter binding, or input filtering before passing values into the database driver. This is a textbook [CWE-89] flaw stemming from absent server-side input validation in /home.php.

Attack Vector

The attack vector is remote and unauthenticated-adjacent: an attacker sends an HTTP GET or POST request to /home.php with a malicious payload appended to the type parameter. Payloads such as UNION-based, boolean-based, or time-based SQL injection probes are sufficient to confirm and exploit the flaw. Public proof-of-concept code is hosted on a GitHub Gist exploit reference and documented in VulDB entry #272802.

No verified code examples are available for inclusion. Refer to the public VulDB submission and the linked GitHub Gist for technical exploitation details.

Detection Methods for CVE-2024-7222

Indicators of Compromise

• HTTP requests to /home.php containing SQL meta-characters in the type parameter, such as single quotes, UNION SELECT, SLEEP(, or -- comment sequences.
• Database error messages referencing MySQL syntax errors logged from the application server.
• Unusual outbound responses with abnormally large payloads from /home.php, indicating data exfiltration via UNION-based injection.
• Web server access logs showing repeated requests to /home.php?type= from a single source IP within a short window.

Detection Strategies

• Deploy a web application firewall (WAF) rule that inspects the type parameter on /home.php and blocks SQL injection signatures.
• Enable MySQL general query logging and alert on queries containing tautologies such as OR 1=1 or stacked statements originating from the Lot Reservation Management application user.
• Correlate web access logs with database query logs to identify malformed type values that result in syntax errors or anomalous result sizes.

Monitoring Recommendations

• Forward web server, application, and MySQL logs to a centralized SIEM for correlation and retention.
• Baseline normal type parameter values used by the application and alert on deviations.
• Monitor for new database users, privilege changes, or schema enumeration queries (information_schema access) that the application would not normally generate.

How to Mitigate CVE-2024-7222

Immediate Actions Required

• Restrict network access to the Lot Reservation Management System to trusted internal networks or VPN users until a fix is applied.
• Deploy WAF rules to block SQL injection payloads targeting /home.php and the type parameter.
• Audit the application database for unauthorized records, new admin accounts, or evidence of data exfiltration.
• Rotate database credentials and any application secrets that may have been exposed.

Patch Information

No official vendor patch has been published by oretnom23 / SourceCodester at the time of NVD publication. Organizations running this application should treat it as unmaintained and consider migration to a supported alternative. Track updates through VulDB CTI #272802 and the VulDB submission record.

Workarounds

• Modify /home.php to use parameterized queries (PDO prepared statements or mysqli_stmt_bind_param) for all user-supplied input, including the type parameter.
• Implement allow-list validation on type, restricting accepted values to a fixed set of expected tokens.
• Run the application database account with the minimum privileges required, removing FILE, DROP, and administrative grants.
• Place the application behind reverse-proxy authentication so that only authenticated, authorized users can reach /home.php.
