CVE-2025-6159: Hostel Management System SQLi Vulnerability

CVE-2025-6159 Overview

A critical SQL injection vulnerability has been identified in code-projects Hostel Management System version 1.0. The vulnerability exists in the /allocate_room.php file, where the search_box parameter fails to properly sanitize user input before incorporating it into SQL queries. This allows remote attackers to manipulate database queries and potentially access, modify, or delete sensitive data stored in the application's database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive hostel management data, or manipulate database records without authorization.

Technical Details for CVE-2025-6159

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the /allocate_room.php endpoint. The application fails to validate, sanitize, or parameterize user-supplied input in the search_box parameter before constructing database queries. When an attacker submits maliciously crafted input through this parameter, the unsanitized data is directly concatenated into SQL statements, allowing arbitrary SQL code execution against the backend database.

The vulnerability is classified under both CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating a fundamental input validation failure that enables injection attacks.

Root Cause

The root cause of this vulnerability is the lack of input validation and parameterized queries in the /allocate_room.php file. The search_box parameter directly accepts user input and incorporates it into SQL queries without proper sanitization or the use of prepared statements. This classic injection flaw allows attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the /allocate_room.php endpoint, injecting SQL payloads through the search_box parameter. Common attack techniques include:

• Union-based injection: Appending UNION SELECT statements to extract data from other database tables
• Boolean-based blind injection: Using conditional statements to infer database contents through application responses
• Time-based blind injection: Utilizing database sleep functions to extract information through response timing
• Error-based injection: Triggering database errors that reveal information about the database structure

The vulnerability is exploitable by sending specially crafted requests containing SQL metacharacters (such as single quotes, double dashes, or UNION keywords) within the search_box parameter. Additional technical details are available in the GitHub CVE Issue and VulDB #312634.

Detection Methods for CVE-2025-6159

Indicators of Compromise

• Unusual database queries or errors in application logs associated with /allocate_room.php
• HTTP requests to /allocate_room.php containing SQL keywords such as UNION, SELECT, DROP, INSERT, or comment sequences (--, /*)
• Unexpected database modifications or unauthorized data access attempts
• High frequency of requests to the vulnerable endpoint with varying search_box parameter values

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests targeting /allocate_room.php
• Enable detailed logging for the Hostel Management System application and monitor for SQL syntax errors
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
• Use intrusion detection systems with SQL injection signature rules focused on the search_box parameter

Monitoring Recommendations

• Monitor web server access logs for requests to /allocate_room.php with suspicious query string patterns
• Set up alerts for database error messages that indicate potential SQL injection attempts
• Review authentication logs for unauthorized access following potential exploitation
• Implement real-time monitoring of database query patterns to identify injection attacks

How to Mitigate CVE-2025-6159

Immediate Actions Required

• Restrict access to the /allocate_room.php endpoint until a patch is applied
• Implement input validation to reject or sanitize special SQL characters in the search_box parameter
• Deploy WAF rules specifically targeting SQL injection attempts against the vulnerable endpoint
• Review database permissions and apply the principle of least privilege to the application's database user

Patch Information

No official vendor patch has been identified for this vulnerability at this time. Organizations using this software should contact the developer or review the Code Projects Resource for updates. Consider migrating to a more actively maintained hostel management solution if patches are not made available.

Workarounds

• Implement prepared statements or parameterized queries in the /allocate_room.php file to prevent SQL injection
• Use a WAF to filter malicious input before it reaches the application
• Restrict network access to the application to trusted IP addresses only
• Disable or remove the vulnerable search functionality if not business-critical
• Implement input validation using allowlists for acceptable characters in the search_box parameter

# Example: Apache mod_rewrite rule to block SQL injection patterns
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|drop|delete|update|concat|char|0x) [NC]
RewriteRule ^allocate_room\.php$ - [F,L]
