CVE-2024-6830 Overview
CVE-2024-6830 is a SQL injection vulnerability in SourceCodester Simple Inventory Management System 1.0, developed by oretnom23. The flaw resides in an unknown function within the action.php file that serves as part of the Order Handler component. Attackers can manipulate the order_id parameter to inject arbitrary SQL statements against the backend database. The vulnerability is remotely exploitable and requires only low privileges. Public disclosure of the exploit details has occurred through VulDB entry VDB-271812, increasing the likelihood of opportunistic attacks against exposed installations.
Critical Impact
Remote authenticated attackers can inject SQL into the order_id parameter of action.php, enabling unauthorized read and write access to inventory database records.
Affected Products
- Oretnom23 Simple Inventory Management System 1.0
- Component: Order Handler (action.php)
- Vulnerable parameter: order_id

Technical Details for CVE-2024-6830
Vulnerability Analysis
The vulnerability is a classic SQL injection flaw [CWE-89] in the Order Handler component of Simple Inventory Management System 1.0. The action.php script accepts an order_id parameter and passes it into a SQL query without proper sanitization or parameterization. Because the application concatenates user-supplied input directly into database statements, attackers can break out of the intended query context and append arbitrary SQL fragments.
Exploitation requires network access to the application and a low-privilege authenticated session. Successful injection can expose customer orders, inventory records, and user credentials stored in the underlying database. Depending on database permissions, attackers may also modify records or extract data through techniques such as UNION-based, boolean-based, or time-based blind SQL injection.
Root Cause
The root cause is missing input validation and the absence of prepared statements when constructing SQL queries in action.php. User-controlled values from the order_id request parameter reach the database layer without escaping or type enforcement. This design pattern violates secure coding practices for PHP database interactions and matches the classic SQL injection weakness described in CWE-89.
Attack Vector
An attacker with a low-privilege account sends a crafted HTTP request to action.php, supplying malicious SQL syntax in the order_id parameter. Because the input is embedded into a backend query without escaping, the injected SQL executes with the privileges of the application's database user. Technical details and a proof-of-concept walkthrough are documented in the public GitHub write-up and in VulDB entry #271812.

Detection Methods for CVE-2024-6830
Indicators of Compromise
- HTTP requests to action.php containing SQL metacharacters such as single quotes, UNION SELECT, --, /*, or SLEEP( in the order_id parameter.
- Web server logs showing unusually long or URL-encoded values supplied to the order_id field.
- Database error messages referencing syntax errors traced back to the Order Handler code path.
- Unexpected read access to tables outside the normal order-management workflow.
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect order_id values for SQL injection signatures and block malformed input.
- Enable database query logging and alert on queries originating from action.php that reference sensitive tables such as users or credentials.
- Correlate authentication logs with anomalous request patterns to identify low-privilege accounts probing the Order Handler endpoint.
Monitoring Recommendations
- Monitor outbound data volumes from the application server to detect bulk extraction of database contents.
- Track failed and successful logins followed immediately by requests to action.php with abnormal parameter lengths.
- Baseline normal order_id values (numeric identifiers) and alert on any non-numeric input reaching the endpoint.
How to Mitigate CVE-2024-6830
Immediate Actions Required
- Restrict network access to the Simple Inventory Management System deployment, placing it behind a VPN or IP allowlist until remediated.
- Deploy WAF signatures that block SQL injection payloads targeting the order_id parameter of action.php.
- Rotate database credentials and audit the application database user's privileges, removing unnecessary write or administrative rights.
- Review web and database logs for evidence of prior exploitation attempts.
Patch Information
No official vendor patch is listed in NVD or VulDB for CVE-2024-6830 at the time of publication. Organizations running Simple Inventory Management System 1.0 should track the vendor's project page for updates and consider migrating to an actively maintained inventory management platform if a fix is not released.
Workarounds
- Modify action.php to use parameterized queries or PDO prepared statements when handling the order_id value.
- Enforce server-side input validation that rejects any order_id value that is not a positive integer.
- Apply the principle of least privilege to the database account used by the application, granting only the minimum permissions required by the Order Handler workflow.
- Disable the Order Handler component entirely if it is not required for business operations.
