CVE-2026-36937: Resort Management System SQLi Vulnerability

CVE-2026-36937 Overview

CVE-2026-36937 is a SQL Injection vulnerability affecting Sourcecodester Online Resort Management System v1.0. The vulnerability exists in the /orms/admin/reservations/view_details.php endpoint, allowing authenticated attackers with administrative privileges to inject malicious SQL queries and potentially extract sensitive information from the database.

Critical Impact

Authenticated administrators can exploit this SQL injection vulnerability to read unauthorized data from the database, potentially exposing guest reservations, personal information, and other sensitive resort management data.

Affected Products

• Sourcecodester Online Resort Management System v1.0
• /orms/admin/reservations/view_details.php endpoint

Technical Details for CVE-2026-36937

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs due to improper neutralization of special elements used in SQL commands. The vulnerable endpoint /orms/admin/reservations/view_details.php fails to properly sanitize user-supplied input before incorporating it into database queries. While the attack requires high privileges (administrative access), successful exploitation can lead to unauthorized disclosure of confidential information stored in the application database.

The vulnerability is network-accessible and requires no user interaction for exploitation. However, the impact is limited to confidentiality breaches affecting a limited scope of data, as the attacker must already possess administrative credentials to exploit this flaw.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries in the view_details.php file. User-controlled parameters are directly concatenated into SQL queries without proper sanitization or the use of prepared statements, enabling SQL injection attacks. This represents a classic example of CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Attack Vector

The attack vector involves an authenticated administrator sending crafted HTTP requests to the /orms/admin/reservations/view_details.php endpoint with malicious SQL payloads embedded in vulnerable parameters. The attacker can leverage standard SQL injection techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection to extract database contents.

Since this requires administrative privileges, the attack surface is limited to scenarios where an attacker has compromised admin credentials or where a malicious insider abuses their elevated access. For technical details on the specific injection point and payload structure, refer to the GitHub SQL Injection Report.

Detection Methods for CVE-2026-36937

Indicators of Compromise

• Unusual SQL syntax patterns in web server logs for requests to /orms/admin/reservations/view_details.php
• Database error messages appearing in application responses indicating malformed queries
• Anomalous query execution times suggesting time-based SQL injection attempts
• Unexpected data access patterns from administrative accounts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to the affected endpoint
• Configure database query logging and alerting for suspicious query patterns including UNION statements, sleep functions, and information_schema access
• Monitor administrative session activity for unusual request volumes or patterns targeting the reservations module

Monitoring Recommendations

• Enable detailed access logging for the /orms/admin/reservations/ directory
• Deploy database activity monitoring to track queries executed against reservation-related tables
• Implement real-time alerting for SQL error conditions in application logs
• Review administrative account access patterns regularly for anomalies

How to Mitigate CVE-2026-36937

Immediate Actions Required

• Restrict network access to the administrative interface to trusted IP addresses only
• Review and audit administrative account credentials and access logs
• Consider temporarily disabling the vulnerable view_details.php endpoint until a patch is available
• Implement Web Application Firewall rules to block common SQL injection patterns

Patch Information

No official vendor patch has been identified at the time of publication. Sourcecodester Online Resort Management System users should monitor for updates from the developer. As this is an open-source project available on Sourcecodester, users may need to apply manual code fixes or implement workarounds until an official patch is released.

Workarounds

• Implement prepared statements with parameterized queries in the affected view_details.php file
• Add input validation and sanitization for all user-supplied parameters before database query execution
• Deploy a Web Application Firewall configured with SQL injection protection rules
• Limit administrative access to the application through network segmentation and VPN requirements

# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule REQUEST_URI "@contains /orms/admin/reservations/view_details.php" \
    "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Blocked',\
    chain"
SecRule ARGS "@detectSQLi" "t:none,t:urlDecodeUni"
