CVE-2024-3523: Campcodes Event Management SQL Vulnerability

CVE-2024-3523 Overview

CVE-2024-3523 is a SQL injection vulnerability in Campcodes Online Event Management System 1.0. The flaw resides in /views/index.php, where the ID parameter is passed directly into a database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements. The vulnerability is remotely exploitable and requires only low-privileged authentication. Public disclosure has occurred, and the issue is tracked as VulDB entry 259894 [CWE-89].

Critical Impact
Remote authenticated attackers can extract, modify, or delete database contents and potentially compromise the confidentiality, integrity, and availability of the application backend.

Technical Details for CVE-2024-3523

Vulnerability Analysis

The vulnerability originates from unsanitized user input in the ID query parameter processed by /views/index.php. The application concatenates the parameter directly into a SQL statement, allowing attackers to break out of the intended query context. An authenticated user with low-level privileges can send crafted HTTP requests over the network to trigger the injection. Successful exploitation grants full read and write access to the underlying database. Because the attack complexity is low and no user interaction is required, exploitation is straightforward once access is obtained.

Root Cause

The root cause is improper neutralization of special elements in a SQL command [CWE-89]. The ID argument is not validated, parameterized, or bound to a prepared statement before being passed to the database driver. Standard defenses such as prepared statements with bound parameters or input allowlisting are absent from the affected code path.

Attack Vector

An authenticated attacker submits an HTTP request to /views/index.php with a malicious value in the ID parameter. Injected SQL payloads can enumerate tables, exfiltrate credentials, escalate privileges within the application, or write records that alter event data. Blind, error-based, and UNION-based techniques are all viable against unparameterized queries of this type. The public disclosure referenced by VulDB entry 259894 and the GitHub vulnerability document describes the exploitation approach.

Detection Methods for CVE-2024-3523

Indicators of Compromise

HTTP requests to /views/index.php containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP, or comment sequences (--, #) in the ID parameter.
Unusual database error messages or long-running queries triggered from the events module.
Unexpected outbound data flows following requests to the affected endpoint.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the ID parameter for SQL injection payloads.
Enable database query logging and alert on queries containing tautologies (for example OR 1=1) or stacked statements originating from the application user.
Correlate authenticated session activity with anomalous query volume against event-related tables.

Monitoring Recommendations

Monitor authentication logs for low-privileged accounts that suddenly access administrative or bulk data endpoints.
Track HTTP 500 responses from /views/index.php, which often accompany error-based SQL injection probing.
Baseline normal request patterns for the events module and alert on deviations in parameter length, encoding, or character distribution.

How to Mitigate CVE-2024-3523

Immediate Actions Required

Restrict access to the Online Event Management System behind authenticated, IP-limited networks until a fix is applied.
Deploy WAF signatures blocking SQL injection patterns targeting the ID parameter of /views/index.php.
Audit database logs for prior exploitation attempts and rotate any credentials or session tokens that may have been exposed.

Patch Information

No vendor advisory or official patch has been published for Campcodes Online Event Management System 1.0 at the time of writing. Refer to the VulDB CTI record for updates. Organizations relying on this application should consider replacing it or applying source-level fixes to convert affected queries to parameterized statements.

Workarounds

Modify /views/index.php to use prepared statements with bound parameters (for example, mysqli::prepare or PDO with placeholders).
Apply strict server-side input validation, casting the ID value to an integer before use in any query.
Restrict database account privileges used by the web application to the minimum required for read and write operations on event tables.

bash

# Example: enforce integer casting before query execution in PHP
$id = filter_input(INPUT_GET, 'ID', FILTER_VALIDATE_INT);
if ($id === false) {
    http_response_code(400);
    exit('Invalid ID');
}
$stmt = $pdo->prepare('SELECT * FROM events WHERE id = :id');
$stmt->execute([':id' => $id]);
