CVE-2024-4796: Campcodes Laundry System SQLi Flaw

CVE-2024-4796 Overview

CVE-2024-4796 is a SQL injection vulnerability in Campcodes Online Laundry Management System 1.0. The flaw resides in the /manage_inv.php script, where the id parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). Public exploit details have been disclosed via VulDB entry 263895 and a proof-of-concept repository on GitHub, increasing the risk of opportunistic exploitation against exposed installations.

Critical Impact
Remote attackers with low-privilege access can execute arbitrary SQL queries against the backend database, leading to disclosure or modification of inventory and customer data.

Technical Details for CVE-2024-4796

Vulnerability Analysis

The vulnerability affects the inventory management component of Campcodes Online Laundry Management System 1.0. Specifically, the manage_inv.php script accepts an id HTTP parameter that is concatenated directly into a SQL statement. Because the application does not validate, escape, or parameterize the input, an attacker can append additional SQL syntax to alter the query logic. Exploitation requires network access to the web application and low-level privileges, but no user interaction. Successful attacks compromise the confidentiality, integrity, and availability of the underlying database in a limited scope, consistent with the CWE-89 classification.

Root Cause

The root cause is the absence of prepared statements or input sanitization in the manage_inv.php handler. User-controlled data from the id GET parameter is passed unfiltered into a dynamically constructed SQL query. This design pattern allows the SQL parser to interpret attacker-supplied metacharacters as query syntax rather than as data.

Attack Vector

Exploitation is performed remotely over HTTP against the vulnerable endpoint. An authenticated user submits a crafted request such as a GET to /manage_inv.php?id=<payload>, where the payload contains SQL fragments including UNION SELECT, boolean-based blind conditions, or time-based delays. The database executes the injected clauses, allowing extraction of table contents, credential hashes, or manipulation of records. Full technical write-up and reproduction steps are available in the GitHub CVE PoC Repository and VulDB #263895.

Detection Methods for CVE-2024-4796

Indicators of Compromise

HTTP requests to /manage_inv.php containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP(, or -- in the id parameter.
Unusually long response times from manage_inv.php consistent with time-based blind SQL injection payloads.
Web server access logs showing repeated requests with incrementing or encoded id values from a single source IP.
Database error messages or stack traces returned in HTTP responses from the inventory endpoint.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the id parameter of manage_inv.php for SQL injection signatures.
Correlate web access logs with database query logs to identify anomalous or malformed queries originating from the inventory module.
Enable database auditing to flag queries containing UNION, INFORMATION_SCHEMA, or unexpected multi-statement execution.

Monitoring Recommendations

Alert on HTTP 500 responses from /manage_inv.php, which often indicate SQL syntax errors triggered during injection probing.
Monitor for outbound data transfers from the database host that exceed typical baselines.
Track authentication events that precede requests to inventory endpoints to identify low-privilege accounts being abused.

How to Mitigate CVE-2024-4796

Immediate Actions Required

Restrict access to the Campcodes Online Laundry Management System behind a VPN or IP allow-list until a vendor fix is available.
Deploy WAF signatures blocking SQL injection payloads targeting the id parameter of manage_inv.php.
Rotate database credentials and audit inventory data for unauthorized modifications.
Enforce least-privilege on the database account used by the web application to limit blast radius.

Patch Information

At the time of publication, no vendor patch is listed in the NVD entry or the referenced VulDB #263895 CTI advisory. Organizations should track vendor communications from Campcodes and apply updates as soon as they are released. In the interim, apply compensating controls at the network and application layers.

Workarounds

Modify manage_inv.php to use parameterized queries or prepared statements for the id value.
Add server-side input validation restricting id to numeric values only, rejecting any request containing non-digit characters.
Disable verbose database error messages in the application configuration to prevent information leakage during probing.

bash

# Example nginx rule to block non-numeric id values on manage_inv.php
location = /manage_inv.php {
    if ($arg_id !~ "^[0-9]+$") {
        return 403;
    }
}
