CVE-2024-7287: Establishment Billing System SQLi Flaw

CVE-2024-7287 Overview

CVE-2024-7287 is a SQL injection vulnerability in SourceCodester Establishment Billing Management System 1.0, developed by oretnom23. The flaw resides in the /manage_user.php script, where the id parameter is passed directly into a SQL query without proper sanitization. An authenticated remote attacker can manipulate the id argument to inject arbitrary SQL statements. The exploit has been publicly disclosed under VulDB identifier VDB-273156, increasing the likelihood of opportunistic exploitation against exposed installations.

Critical Impact
Remote attackers with low-privileged access can inject SQL statements through the id parameter of /manage_user.php, exposing user records and potentially enabling authentication tampering.

Technical Details for CVE-2024-7287

Vulnerability Analysis

The vulnerability is classified under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command. The manage_user.php endpoint accepts an id parameter from the HTTP request and concatenates it into a SQL query without parameterization or input validation. Attackers can supply crafted values that alter the query logic, extract database contents, or modify records.

The attack is remote and requires low privileges but no user interaction. Because the application manages billing and user data, successful exploitation can expose personally identifiable information (PII), payment records, and administrative account details.

Root Cause

The root cause is the direct interpolation of user-controlled input into a SQL statement inside manage_user.php. The code path does not use prepared statements or parameterized queries. It also does not apply type casting or allow-list validation on the numeric id argument.

Attack Vector

An attacker sends a crafted HTTP request to /manage_user.php with a manipulated id query parameter. Payloads typically include boolean-based, union-based, or time-based SQL injection techniques to enumerate database schema and exfiltrate rows. Public proof-of-concept material has been published as a GitHub Gist PoC Resource and referenced in the VulDB Entry #273156.

No verified exploit code is republished here. Refer to the vendor and third-party references for technical proof-of-concept details.

Detection Methods for CVE-2024-7287

Indicators of Compromise

HTTP requests to /manage_user.php containing SQL metacharacters in the id parameter, such as single quotes, UNION SELECT, SLEEP(, or -- comment sequences.
Web server access logs showing repeated id= values with abnormal length or encoded payloads.
Database error messages returned in HTTP responses referencing MySQL syntax exceptions.
Unexpected read or write activity against the users table originating from the web application account.

Detection Strategies

Deploy Web Application Firewall (WAF) rules to flag SQL injection patterns targeting the id parameter on /manage_user.php.
Enable database query logging and alert on queries containing tautologies (OR 1=1), stacked statements, or INFORMATION_SCHEMA access from the billing application.
Correlate web server logs with authentication events to identify session anomalies following requests to manage_user.php.

Monitoring Recommendations

Monitor outbound data volumes from the database host for signs of bulk record exfiltration.
Alert on privileged database operations initiated by the PHP application service account outside normal usage windows.
Track failed and successful logins for administrative users following suspicious requests to the affected endpoint.

How to Mitigate CVE-2024-7287

Immediate Actions Required

Restrict network access to the Establishment Billing Management System 1.0 application. Place it behind a VPN or IP allow-list until a fix is applied.
Deploy WAF rules that block SQL injection payloads on /manage_user.php and enforce numeric-only validation on the id parameter.
Rotate database credentials and administrative account passwords used by the application.
Audit the users and billing tables for unauthorized modifications since the application was exposed.

Patch Information

No vendor patch or security advisory has been published for CVE-2024-7287 at the time of writing. The affected product is SourceCodester Establishment Billing Management System 1.0, and no updated release is listed in the VulDB CTI ID #273156 entry. Organizations running this software should treat it as unpatched and apply compensating controls.

Workarounds

Refactor manage_user.php to use prepared statements with parameterized queries via PDO or mysqli_prepare.
Cast the id parameter to an integer with intval() before use, and reject any non-numeric input.
Apply the principle of least privilege to the database account used by the application, removing DDL and cross-table privileges.
Disable public internet exposure of the application if it is not required for business operations.

bash

# Configuration example: NGINX rule to block non-numeric id values on manage_user.php
location = /manage_user.php {
    if ($arg_id !~ "^[0-9]+$") {
        return 403;
    }
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php/php-fpm.sock;
