CVE-2025-6332: PHPGurukul Directory Management SQL Injection

CVE-2025-6332 Overview

CVE-2025-6332 is a SQL injection vulnerability in PHPGurukul Directory Management System 2.0. The flaw resides in the /admin/manage-directory.php script, where the del parameter is concatenated into a SQL query without proper sanitization. An authenticated attacker with low-privilege access can manipulate the parameter remotely to alter query logic. Public disclosure of the exploit details increases the risk of opportunistic targeting against exposed installations. The issue is tracked under [CWE-89] (SQL Injection) and [CWE-74] (Injection).

Critical Impact
Remote attackers with low privileges can inject arbitrary SQL through the del parameter, potentially exposing or modifying directory data stored in the backend database.

Technical Details for CVE-2025-6332

Vulnerability Analysis

The vulnerability exists in the administrative directory management workflow of PHPGurukul Directory Management System 2.0. The /admin/manage-directory.php script processes a del request parameter used to identify directory entries for deletion. The application passes this parameter into a SQL statement without parameterization or input validation. As a result, an attacker can append SQL syntax that the database executes against the underlying schema. Exploitation requires network access to the admin interface and a low-privilege authenticated session. Successful exploitation can lead to disclosure of stored directory records, modification of database content, and reconnaissance against the broader database schema. The exploit has been disclosed publicly via the referenced GitHub issue, lowering the effort required to weaponize the flaw.

Root Cause

The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. The del parameter is interpolated directly into a query string rather than bound through a prepared statement. PHP database APIs such as PDO or mysqli with parameter binding would prevent the injection, but the affected code path relies on string concatenation.

Attack Vector

The attack vector is network-based. An attacker authenticated to the admin panel sends a crafted HTTP request to /admin/manage-directory.php with a malicious del value. Typical payloads include boolean-based, UNION-based, or time-based SQL injection techniques to extract data or enumerate tables. No user interaction is required beyond the attacker's own session.

The vulnerability manifests in the deletion handler of manage-directory.php where the del query string value is appended to a DELETE or SELECT statement. See the GitHub Issue Discussion for proof-of-concept request details and the VulDB #313328 entry for additional technical context.

Detection Methods for CVE-2025-6332

Indicators of Compromise

HTTP requests to /admin/manage-directory.php containing SQL metacharacters such as single quotes, UNION SELECT, SLEEP(, or comment sequences (--, #) inside the del parameter.
Unexpected database errors in PHP or web server logs referencing the manage-directory.php script.
Anomalous administrative session activity originating from unfamiliar IP addresses or user agents.

Detection Strategies

Inspect web server access logs for del= query strings carrying non-numeric or encoded SQL payloads against manage-directory.php.
Deploy a web application firewall (WAF) rule that flags SQL injection signatures targeting the admin endpoint.
Correlate admin authentication events with subsequent database errors to identify post-login injection attempts.

Monitoring Recommendations

Enable MySQL general or audit logging to capture queries originating from the application user, focusing on DELETE statements with embedded subqueries.
Alert on bursts of HTTP 500 responses tied to the admin directory script.
Track outbound database traffic volume from the web server to detect bulk data exfiltration through UNION-based injection.

How to Mitigate CVE-2025-6332

Immediate Actions Required

Restrict access to /admin/ paths through IP allowlisting or VPN-only access until a fix is applied.
Rotate administrative credentials and database service account passwords used by the application.
Deploy a WAF rule to block SQL injection patterns in the del parameter on manage-directory.php.
Review database logs for prior exploitation attempts and validate the integrity of directory tables.

Patch Information

No vendor patch has been published in the referenced advisories at the time of NVD publication. Monitor PHP Gurukul Security Resources and the VulDB CTI ID #313328 tracker for updated fix availability. Until an official update is released, apply the workarounds below and consider isolating the application.

Workarounds

Modify manage-directory.php to use prepared statements with bound parameters via PDO or mysqli instead of concatenating the del value.
Cast the del parameter to an integer ((int)$_GET['del']) before use, since directory identifiers are numeric.
Enforce least-privilege on the MySQL account used by the application to limit the impact of successful injection.
Take the admin interface offline if it is not actively required for business operations.

bash

# Example mitigation: enforce integer casting in PHP
# Replace direct usage of $_GET['del'] with a sanitized integer
$del_id = isset($_GET['del']) ? (int)$_GET['del'] : 0;
if ($del_id > 0) {
    $stmt = $pdo->prepare('DELETE FROM tbldirectory WHERE id = :id');
    $stmt->execute([':id' => $del_id]);
}
