CVE-2026-36942: Resort Management System SQLi Vulnerability

CVE-2026-36942 Overview

CVE-2026-36942 is a SQL Injection vulnerability affecting Sourcecodester Online Resort Management System v1.0. The vulnerability exists in the file /orms/admin/activities/manage_activity.php, which fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows authenticated attackers with high privileges to manipulate database queries through crafted input parameters.

Critical Impact

Authenticated attackers with administrative access can exploit this SQL injection flaw to extract sensitive information from the database, potentially compromising guest records, reservation data, and other confidential resort management information.

Affected Products

• Sourcecodester Online Resort Management System v1.0
• Online Resort Management System - /orms/admin/activities/manage_activity.php endpoint

Technical Details for CVE-2026-36942

Vulnerability Analysis

This SQL Injection vulnerability resides in the activity management functionality of the Online Resort Management System's administrative panel. The vulnerable endpoint /orms/admin/activities/manage_activity.php processes user input without adequate sanitization or parameterization, allowing SQL statements to be injected through manipulated parameters.

The attack requires network access and high-level privileges (administrative authentication), which limits the attack surface. However, once an attacker obtains administrative credentials through other means (phishing, credential stuffing, or insider access), they can leverage this vulnerability to directly interact with the backend database.

The impact is primarily confidentiality-focused, allowing unauthorized data extraction from the database. The vulnerability does not directly enable integrity or availability impacts according to the assessment.

Root Cause

The root cause of this vulnerability is improper input validation and the use of unsanitized user input in SQL query construction. The manage_activity.php script directly concatenates user-controlled parameters into SQL statements without using prepared statements or proper input sanitization techniques.

PHP applications using deprecated mysql_* functions or improperly implemented PDO/MySQLi connections without parameterized queries are particularly susceptible to this class of vulnerability.

Attack Vector

The attack vector is network-based, requiring the attacker to authenticate to the administrative panel with high-privilege credentials. Once authenticated, the attacker can inject malicious SQL syntax through form fields or URL parameters processed by the manage_activity.php endpoint.

Typical exploitation involves injecting SQL payloads such as UNION-based queries to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based blind injection when direct output is not visible.

Detection Methods for CVE-2026-36942

Indicators of Compromise

• Unusual SQL error messages in web application logs originating from /orms/admin/activities/manage_activity.php
• HTTP requests to the manage_activity.php endpoint containing SQL syntax characters (', ", ;, --, UNION, SELECT)
• Database query logs showing malformed or suspicious queries from the resort management application
• Unexpected data extraction patterns or large query results from the activities table

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to /orms/admin/activities/
• Enable detailed database query logging and monitor for anomalous query structures
• Implement application-level logging to capture all parameters passed to the manage_activity.php endpoint
• Configure intrusion detection systems (IDS) to alert on common SQL injection signatures in HTTP traffic

Monitoring Recommendations

• Monitor administrative panel access logs for unusual login patterns or access from unexpected IP addresses
• Set up alerts for database errors or exceptions generated by the resort management application
• Review web server access logs for repeated requests to manage_activity.php with varying payloads
• Implement real-time monitoring for data exfiltration attempts through unusually large query responses

How to Mitigate CVE-2026-36942

Immediate Actions Required

• Restrict access to the administrative panel to trusted IP addresses only
• Review and audit all administrative user accounts for unauthorized access
• Implement additional authentication controls (MFA) for administrative access
• Consider temporarily disabling the activities management feature until patched
• Monitor database access patterns for signs of data exfiltration

Patch Information

No official patch has been released by Sourcecodester at the time of publication. Organizations using the Online Resort Management System should monitor the vendor's official channels for security updates. As this is an open-source project distributed through Sourcecodester, users may need to implement manual code fixes.

For technical details about the vulnerability, see the GitHub SQL Injection Report.

Workarounds

• Implement input validation and sanitization for all user-supplied parameters in manage_activity.php
• Convert all database queries to use prepared statements with parameterized queries
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Restrict administrative panel access through network segmentation or VPN requirements
• Apply the principle of least privilege to database user accounts used by the application

# Example: Restrict access to admin panel via Apache .htaccess
# Place in /orms/admin/.htaccess
<Directory "/var/www/html/orms/admin">
    Order Deny,Allow
    Deny from all
    Allow from 10.0.0.0/8
    Allow from 192.168.1.0/24
</Directory>
