CVE-2025-7160: Zoo Management System SQL Injection Flaw

CVE-2025-7160 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Zoo Management System version 2.1. The vulnerability exists in the administrative login functionality at /admin/index.php, where the Username parameter is susceptible to SQL injection attacks. This flaw allows remote attackers to manipulate SQL queries through specially crafted input, potentially bypassing authentication and gaining unauthorized access to the administrative interface.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, access sensitive zoo management data, and potentially compromise the entire underlying database system.

Affected Products

• PHPGurukul Zoo Management System 2.1
• Web servers hosting the vulnerable Zoo Management System application
• Databases connected to the Zoo Management System

Technical Details for CVE-2025-7160

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs in the administrative authentication mechanism of the Zoo Management System. The vulnerability is network-accessible and requires no authentication or user interaction to exploit, making it particularly dangerous for exposed installations.

The vulnerable endpoint accepts user-supplied input in the Username field without proper sanitization or parameterization. When an attacker provides malicious SQL syntax as part of the username value, the application directly incorporates this input into database queries, allowing the attacker to manipulate the query logic.

Successful exploitation could enable attackers to bypass login authentication entirely, extract sensitive data from the database including administrator credentials and zoo operational information, modify or delete database records, and potentially achieve further system compromise depending on database permissions.

Root Cause

The root cause is insufficient input validation and the use of unsanitized user input in SQL queries. The /admin/index.php file fails to properly escape or parameterize the Username argument before including it in database operations. This classic SQL injection pattern occurs when dynamic SQL queries are constructed through string concatenation rather than using prepared statements with bound parameters.

Attack Vector

The attack is network-based and can be initiated remotely without authentication. An attacker sends a crafted HTTP request to the /admin/index.php endpoint with a malicious payload in the Username parameter. The attack requires low complexity and no special privileges, making it accessible to unskilled attackers using readily available SQL injection tools and techniques.

The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Attackers can leverage common SQL injection payloads such as authentication bypass strings, UNION-based extraction queries, or time-based blind injection techniques to compromise vulnerable installations.

Detection Methods for CVE-2025-7160

Indicators of Compromise

• Unusual SQL error messages in application logs originating from /admin/index.php
• Multiple failed login attempts with suspicious Username values containing SQL syntax characters (single quotes, double dashes, UNION keywords)
• Unexpected database queries or data access patterns in database audit logs
• Web server logs showing requests to /admin/index.php with encoded or anomalous Username parameters

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in login requests
• Configure intrusion detection systems to alert on SQL injection signatures targeting the administrative login endpoint
• Implement application-level logging to capture and analyze all authentication attempts with parameter details
• Enable database query logging to identify anomalous or malformed queries originating from the web application

Monitoring Recommendations

• Monitor web server access logs for high-frequency requests to /admin/index.php from single IP addresses
• Set up alerts for database errors that indicate SQL injection attempts such as syntax errors or unexpected query results
• Track failed authentication events and correlate with suspicious input patterns
• Implement real-time log analysis to detect attack patterns before successful compromise

How to Mitigate CVE-2025-7160

Immediate Actions Required

• Restrict network access to the /admin/index.php endpoint to trusted IP addresses only using firewall rules or web server configuration
• Deploy a Web Application Firewall with SQL injection protection rules in front of the vulnerable application
• Disable or take offline the Zoo Management System administrative interface until a patch is available
• Review database logs for evidence of prior exploitation and assess potential data compromise

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Administrators should monitor the PHPGurukul website for security updates. The vulnerability details are tracked in VulDB #315099 and the GitHub Issue Report.

Workarounds

• Implement input validation at the web server level using ModSecurity or similar WAF solutions to filter SQL injection payloads
• Apply network segmentation to isolate the Zoo Management System from critical infrastructure
• Use a reverse proxy with SQL injection filtering capabilities to intercept malicious requests
• Consider implementing application-level fixes by modifying the source code to use prepared statements (requires PHP development expertise)

# Example: Apache ModSecurity rule to block SQL injection in login forms
