CVE-2025-2419: Real Estate Management System SQL Injection

CVE-2025-2419 Overview

CVE-2025-2419 is a SQL injection vulnerability in code-projects Real Estate Property Management System 1.0, developed by Fabian. The flaw resides in the /InsertFeedback.php endpoint, where the txtName, txtEmail, txtMobile, and txtFeedback parameters are passed to a database query without proper sanitization. Remote attackers can manipulate these inputs to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed instances. The issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization in Output).

Critical Impact
Unauthenticated or low-privileged remote attackers can inject SQL payloads through feedback form fields, potentially exposing or modifying backend database records.

Technical Details for CVE-2025-2419

Vulnerability Analysis

The vulnerability exists in the feedback submission workflow of Real Estate Property Management System 1.0. The /InsertFeedback.php script accepts user-supplied form input and concatenates the values directly into a SQL statement. Because the application does not use parameterized queries or input validation, attackers can break out of the intended SQL context and append arbitrary clauses.

The exploit is reachable over the network and requires no authentication or user interaction beyond submitting the feedback form. Public disclosure of the technique means proof-of-concept payloads are documented in third-party references such as VulDB #299916 and the GitHub CVE Documentation.

Root Cause

The root cause is the absence of prepared statements and input sanitization in the PHP handler for the feedback form. User-controlled values from txtName, txtEmail, txtMobile, and txtFeedback are interpolated directly into the SQL query string. This violates safe data-access practices outlined in CWE-89.

Attack Vector

An attacker submits a crafted HTTP POST request to /InsertFeedback.php, replacing one of the vulnerable parameters with a SQL injection payload. The injected statement executes within the application's database context, enabling data extraction, modification, or enumeration of database schema. Because the attack uses standard HTTP, no special tooling beyond a browser or curl is required.

No verified proof-of-concept code is available from the vendor. Refer to the VulDB CTI #299916 entry for additional technical context.

Detection Methods for CVE-2025-2419

Indicators of Compromise

HTTP POST requests to /InsertFeedback.php containing SQL meta-characters such as ', --, ;, UNION, or SELECT in the txtName, txtEmail, txtMobile, or txtFeedback parameters.
Database error messages or stack traces returned in HTTP responses from the feedback endpoint.
Unexpected INSERT, UPDATE, or SELECT activity in MySQL/MariaDB logs originating from the application's database user.

Detection Strategies

Inspect web server access logs for anomalous payload patterns or oversized values submitted to /InsertFeedback.php.
Deploy a Web Application Firewall (WAF) with SQL injection rule sets and enable alerting on blocked requests targeting feedback endpoints.
Correlate web request logs with database query logs to identify malformed or suspicious queries tied to feedback submissions.

Monitoring Recommendations

Forward web server and database logs to a centralized SIEM for retention and pattern analysis.
Alert on HTTP 500 responses from /InsertFeedback.php, which often indicate failed injection attempts.
Baseline normal feedback submission rates and alert on sudden volume spikes from a single source IP.

How to Mitigate CVE-2025-2419

Immediate Actions Required

Restrict access to the Real Estate Property Management System administrative and public-facing endpoints via network ACLs or VPN until remediation is complete.
Disable or remove the /InsertFeedback.php endpoint if the feedback feature is not in active use.
Audit the database user account used by the application and reduce its privileges to the minimum required.

Patch Information

No official vendor patch has been published in the references reviewed. Operators should monitor the Code Projects Resource site for updates. In the interim, apply source-level fixes by replacing string-concatenated SQL with parameterized queries using PHP PDO or mysqli prepared statements, and validate all input against strict allowlists.

Workarounds

Implement a WAF rule that blocks SQL meta-characters in POST parameters submitted to /InsertFeedback.php.
Add server-side input validation to enforce expected formats for name, email, and mobile fields before they reach the database layer.
Run the application database account with read/write-restricted permissions and remove DROP, ALTER, and FILE privileges.
If feasible, take the affected instance offline until source code can be remediated.

bash

# Example PHP remediation pattern using PDO prepared statements
$stmt = $pdo->prepare(
  "INSERT INTO feedback (name, email, mobile, feedback) VALUES (:name, :email, :mobile, :feedback)"
);
$stmt->execute([
  ':name'     => $_POST['txtName'],
  ':email'    => $_POST['txtEmail'],
  ':mobile'   => $_POST['txtMobile'],
  ':feedback' => $_POST['txtFeedback'],
]);
