CVE-2024-6014: Document Management System SQLi Flaw

CVE-2024-6014 Overview

CVE-2024-6014 is a SQL injection vulnerability in itsourcecode Document Management System 1.0. The flaw resides in the edithis.php script, where the id parameter is passed directly into a database query without proper sanitization. Attackers can exploit this issue remotely over the network with low-privileged access. The vulnerability is tracked under VulDB identifier VDB-268722 and is classified under CWE-89. Public disclosure of the exploit details increases the likelihood of opportunistic attacks against exposed instances.

Critical Impact

Remote attackers can manipulate the id parameter in edithis.php to inject arbitrary SQL statements, potentially exposing or altering document metadata stored in the backend database.

Affected Products

• itsourcecode Document Management System 1.0
• edithis.php component
• Deployments built from the itsourcecode PHP source distribution

Technical Details for CVE-2024-6014

Vulnerability Analysis

The vulnerability stems from improper neutralization of user-supplied input in the edithis.php script of itsourcecode Document Management System 1.0. The id parameter is incorporated into a SQL query without prepared statements or input validation. Attackers append crafted SQL syntax to the parameter to break out of the intended query context.

Successful exploitation allows reading, modifying, or deleting database records associated with document records. The impact remains scoped to the application database based on the limited confidentiality, integrity, and availability values in the CVSS vector. Because the application requires authenticated access at a low privilege level, any registered user can trigger the flaw.

Root Cause

The root cause is missing parameterization of SQL queries built from HTTP request parameters in edithis.php. The application concatenates the id value directly into the query string, satisfying the conditions for [CWE-89] SQL Injection.

Attack Vector

The attack vector is network-based. An authenticated attacker sends a crafted HTTP request to edithis.php containing SQL metacharacters in the id parameter. No user interaction is required, and the exploit has been disclosed publicly through the GitHub CVE Issue and VulDB #268722.

The vulnerability manifests when the id GET or POST parameter is reflected into the underlying SQL statement. Refer to the public technical reference at VulDB CTII ID #268722 for proof-of-concept details.

Detection Methods for CVE-2024-6014

Indicators of Compromise

• HTTP requests to edithis.php containing SQL metacharacters such as single quotes, UNION SELECT, OR 1=1, or comment sequences -- and /* in the id parameter.
• Unexpected database errors, query timeouts, or anomalous response sizes returned from edithis.php.
• Web server access logs showing repeated parameter tampering against the id value from a single source.

Detection Strategies

• Deploy web application firewall (WAF) signatures that detect SQL injection patterns targeting the id parameter of edithis.php.
• Enable database query logging and alert on syntactically malformed queries originating from the Document Management System service account.
• Correlate authentication logs with HTTP request patterns to identify low-privileged accounts probing the application for injection points.

Monitoring Recommendations

• Forward web server and database logs to a centralized analytics platform for retention and correlation.
• Baseline normal parameter values for edithis.php and alert on deviations such as encoded SQL keywords.
• Monitor outbound connections from the database host for signs of data exfiltration following suspicious queries.

How to Mitigate CVE-2024-6014

Immediate Actions Required

• Restrict network access to the Document Management System to trusted networks or place it behind a VPN until a fix is applied.
• Disable or remove the edithis.php endpoint if it is not required for business operations.
• Audit the application database for unauthorized modifications, new accounts, or unexpected data changes.

Patch Information

No vendor patch is referenced in the published advisory data. Administrators should monitor the itsourcecode project page and the GitHub disclosure issue for remediation guidance. In the absence of an official update, organizations should modify the source code to use parameterized queries or prepared statements (mysqli_prepare or PDO with bound parameters).

Workarounds

• Implement server-side input validation that restricts the id parameter to numeric values only.
• Deploy a WAF rule that blocks SQL injection signatures targeting edithis.php.
• Apply least-privilege database permissions so the application account cannot read or modify tables outside its required scope.
