CVE-2025-6153: Hostel Management System SQLi Vulnerability

CVE-2025-6153 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Hostel Management System version 1.0. This vulnerability exists in the /admin/students.php file, where the search_box parameter is not properly sanitized before being used in SQL queries. An unauthenticated remote attacker can exploit this flaw to execute arbitrary SQL commands against the backend database, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive student and hostel data, modify database records, or potentially gain further access to the underlying system.

Technical Details for CVE-2025-6153

Vulnerability Analysis

This SQL injection vulnerability affects the admin students management functionality within PHPGurukul Hostel Management System. The vulnerable endpoint /admin/students.php accepts user input through the search_box parameter without implementing proper input validation or parameterized queries. When administrators search for student records, the search term is directly concatenated into SQL queries, creating an injection point that attackers can exploit remotely without authentication.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user-controllable input is improperly handled before being passed to an interpreter.

Root Cause

The root cause of this vulnerability is the failure to implement proper input sanitization and parameterized queries (prepared statements) in the PHP code handling the student search functionality. The search_box parameter value is directly incorporated into SQL query strings without escaping special characters or using bound parameters, allowing attackers to inject malicious SQL syntax that alters the intended query logic.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /admin/students.php endpoint with specially crafted payloads in the search_box parameter. These payloads can include SQL syntax designed to:

• Extract sensitive data from the database using UNION-based or error-based injection techniques
• Bypass authentication mechanisms by manipulating query conditions
• Modify or delete database records through stacked queries (if supported)
• Potentially escalate to operating system command execution depending on database configuration

The exploit has been publicly disclosed, making it accessible to threat actors. Attackers can probe the application using common SQL injection testing payloads such as single quotes, boolean conditions, and time-based delays to confirm the vulnerability and refine their attack approach.

Detection Methods for CVE-2025-6153

Indicators of Compromise

• Unusual HTTP requests to /admin/students.php containing SQL syntax characters (single quotes, semicolons, UNION, SELECT, etc.) in the search_box parameter
• Database error messages appearing in application logs or HTTP responses indicating malformed SQL queries
• Unexpected database queries or query patterns in database audit logs, particularly involving student-related tables
• Signs of data exfiltration or unauthorized database access in application or database logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP parameters
• Implement database activity monitoring to identify anomalous query patterns or unauthorized data access attempts
• Enable detailed logging for the /admin/students.php endpoint and monitor for suspicious input patterns
• Configure intrusion detection systems (IDS) with signatures for SQL injection attack payloads

Monitoring Recommendations

• Monitor web server access logs for requests to /admin/students.php with encoded or suspicious parameter values
• Set up alerts for database errors that may indicate injection attempts, such as syntax errors or unauthorized access attempts
• Review database query logs for unusual patterns including UNION statements, subqueries, or time-based functions that may indicate exploitation

How to Mitigate CVE-2025-6153

Immediate Actions Required

• Restrict access to the /admin/students.php endpoint using network-level controls or IP whitelisting until a patch is available
• Implement a Web Application Firewall with SQL injection protection rules in front of the application
• Review database user permissions and apply the principle of least privilege to limit potential damage from successful exploitation
• Monitor for exploitation attempts using the detection strategies outlined above

Patch Information

At the time of writing, no official patch has been released by PHPGurukul for this vulnerability. Organizations using PHPGurukul Hostel Management System should monitor the PHP Gurukul Website for security updates. Additional technical details are available through VulDB #312628 and the GitHub Issue for CVE-1.

Workarounds

• Implement input validation on the search_box parameter to allow only alphanumeric characters and expected search patterns
• Modify the vulnerable PHP code to use prepared statements with parameterized queries instead of string concatenation
• Deploy the application behind a reverse proxy with SQL injection filtering capabilities
• Consider temporarily disabling the student search functionality if it is not critical to operations
