CVE-2025-1850: College Management System SQLi Vulnerability

CVE-2025-1850 Overview

A critical SQL injection vulnerability has been identified in Codezips College Management System version 1.0. The vulnerability exists in the /university.php file where the book_name parameter is improperly handled, allowing attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

This SQL injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands against the database, potentially compromising sensitive student records, administrative data, and system integrity.

Affected Products

• Codezips College Management System 1.0
• PHP-based educational institution management platforms using vulnerable codebase

Technical Details for CVE-2025-1850

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the /university.php file within the Codezips College Management System. The book_name parameter accepts user-supplied input that is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to escape the intended query context and inject arbitrary SQL commands.

The vulnerability is exploitable remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious requests containing SQL metacharacters and commands that will be executed by the database server with the privileges of the application's database user account.

Root Cause

The root cause is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), specifically manifesting as SQL injection. The application fails to properly sanitize, escape, or parameterize user input before including it in database queries. The book_name parameter in /university.php is directly concatenated into SQL statements, allowing injection of arbitrary SQL syntax.

Attack Vector

The attack is network-based and can be launched remotely against any exposed instance of the vulnerable application. The attack flow involves:

1. An attacker identifies an exposed Codezips College Management System instance
2. The attacker sends a crafted HTTP request to /university.php with malicious SQL code in the book_name parameter
3. The unsanitized input is incorporated into a database query
4. The database executes the injected SQL commands
5. The attacker gains unauthorized access to data or can manipulate database contents

The vulnerability has been publicly disclosed and exploit information is available through GitHub CVE Documentation, increasing the risk of exploitation in the wild.

Detection Methods for CVE-2025-1850

Indicators of Compromise

• Unusual HTTP requests to /university.php containing SQL metacharacters such as single quotes, double dashes, semicolons, or UNION keywords in the book_name parameter
• Database error messages appearing in application logs indicating malformed SQL syntax
• Unexpected database query patterns or elevated database activity from the web application user account
• Evidence of data exfiltration or unauthorized modifications to student records or administrative tables

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in requests to /university.php
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
• Enable detailed logging on the database server to capture and alert on suspicious query patterns
• Monitor application logs for unusual error messages related to database operations

Monitoring Recommendations

• Establish baseline metrics for normal database query volumes and alert on significant deviations
• Configure real-time alerting for web server logs showing requests with SQL injection indicators to the /university.php endpoint
• Implement database activity monitoring to track queries executed by the application's database user
• Review access logs regularly for requests originating from unexpected geographic locations or IP addresses

How to Mitigate CVE-2025-1850

Immediate Actions Required

• Restrict network access to the Codezips College Management System to trusted IP ranges or internal networks only
• Implement input validation and filtering at the web application firewall level to block requests containing SQL injection patterns
• Consider taking the application offline until a secure version is available if it processes sensitive data
• Review database logs for any evidence of prior exploitation and assess potential data breach impact

Patch Information

No official vendor patch has been released for this vulnerability at the time of publication. Administrators should monitor VulDB and the vendor's official channels for security updates. Given the lack of vendor response, organizations using this software should evaluate alternative solutions or implement comprehensive compensating controls.

Workarounds

• Apply input validation at the application or WAF level to reject requests containing SQL metacharacters in the book_name parameter
• Implement network segmentation to limit database server access exclusively to the application server
• Use database user accounts with minimal required privileges to reduce the impact of successful exploitation
• Consider deploying a reverse proxy with SQL injection detection capabilities in front of the application
