CVE-2025-4304: Cyber Cafe Management System SQLi Flaw

CVE-2025-4304 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Cyber Cafe Management System version 1.0. The vulnerability exists in the /adminprofile.php file where improper handling of the mobilenumber parameter allows attackers to inject malicious SQL statements. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify database contents, or potentially gain administrative access to the Cyber Cafe Management System without authentication.

Affected Products

• PHPGurukul Cyber Cafe Management System 1.0
• Other parameters in /adminprofile.php may also be affected

Technical Details for CVE-2025-4304

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from insufficient input validation in the /adminprofile.php endpoint. The application fails to properly sanitize user-supplied input in the mobilenumber parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the privileges of the application's database user.

The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that the root cause involves failure to neutralize special characters that could be interpreted as SQL syntax.

Root Cause

The root cause of this vulnerability is the direct incorporation of user input into SQL queries without proper parameterization or input sanitization. The mobilenumber field in the admin profile functionality accepts user-controlled data that is concatenated directly into database queries, allowing malicious actors to escape the intended query structure and inject additional SQL commands.

PHP applications that construct SQL queries through string concatenation rather than prepared statements or parameterized queries are particularly susceptible to this class of vulnerability. The CVE description notes that other parameters in the affected file may also be vulnerable, suggesting a systemic pattern of insecure coding practices.

Attack Vector

The attack can be executed remotely over the network without requiring authentication. An attacker can craft malicious HTTP requests to the /adminprofile.php endpoint, injecting SQL payloads through the mobilenumber parameter. The exploit has been publicly disclosed, making this vulnerability actively exploitable by threat actors with minimal technical expertise.

Typical attack scenarios include:

• Union-based SQL injection to extract data from other database tables
• Boolean-based blind SQL injection to enumerate database contents
• Time-based blind SQL injection for data exfiltration
• Stacked queries to modify or delete database records

The vulnerability can be exploited by sending specially crafted values in the mobilenumber field that break out of the expected query context and append malicious SQL statements. Technical details and proof-of-concept information are available in the GitHub Issue Discussion.

Detection Methods for CVE-2025-4304

Indicators of Compromise

• HTTP requests to /adminprofile.php containing SQL syntax characters such as single quotes, double quotes, semicolons, or SQL keywords in the mobilenumber parameter
• Unusual database query patterns or errors in application logs indicating malformed SQL statements
• Unexpected data access patterns or bulk data retrieval from the database
• Web server access logs showing requests with URL-encoded SQL injection payloads targeting the admin profile endpoint

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests to the Cyber Cafe Management System
• Implement database activity monitoring to identify anomalous query execution, particularly queries with unusual structure or accessing unexpected tables
• Configure application logging to capture all requests to /adminprofile.php with full parameter values for security analysis
• Utilize SentinelOne's Singularity platform to detect post-exploitation activities that may follow successful SQL injection attacks

Monitoring Recommendations

• Enable verbose logging on the web server and database server to capture detailed request and query information
• Monitor for unusual network traffic patterns that may indicate data exfiltration following successful exploitation
• Set up alerts for multiple failed or malformed database queries that could indicate probing or exploitation attempts
• Review access logs regularly for suspicious patterns targeting PHP administrative endpoints

How to Mitigate CVE-2025-4304

Immediate Actions Required

• Restrict network access to the /adminprofile.php endpoint to trusted IP addresses only using firewall rules or web server configuration
• Implement a Web Application Firewall (WAF) with SQL injection detection rules to filter malicious requests
• Consider taking the affected application offline or restricting access until a patch is available
• Review database permissions to ensure the application uses a least-privilege database account

Patch Information

As of the last update on 2025-05-13, no official vendor patch has been released for this vulnerability. Organizations using PHPGurukul Cyber Cafe Management System 1.0 should monitor the PHP Gurukul Homepage for security updates. Additional vulnerability tracking information is available through VulDB #307407.

Workarounds

• Implement input validation at the application level by modifying the source code to use prepared statements with parameterized queries for all database operations
• Deploy a reverse proxy or WAF configured to block requests containing SQL injection patterns in the mobilenumber parameter
• Restrict access to administrative functions using additional authentication layers such as IP whitelisting or VPN requirements
• Consider implementing database query logging and anomaly detection to identify and block exploitation attempts in real-time
