CVE-2025-7164: Cyber Cafe Management System SQLi Flaw

CVE-2025-7164 Overview

A critical SQL injection vulnerability has been discovered in PHPGurukul Cyber Cafe Management System version 1.0. The vulnerability exists in the /index.php file where the Username parameter is improperly sanitized, allowing attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries without authentication, potentially compromising the entire application's data integrity and confidentiality.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system through the vulnerable Username parameter.

Affected Products

• PHPGurukul Cyber Cafe Management System 1.0
• Campcodes Cyber Cafe Management System 1.0

Technical Details for CVE-2025-7164

Vulnerability Analysis

This SQL injection vulnerability affects the login functionality of the Cyber Cafe Management System. The application fails to properly sanitize user-supplied input in the Username parameter before incorporating it into SQL queries. When users submit login credentials through /index.php, the application directly concatenates the username value into database queries without using prepared statements or parameterized queries. This allows attackers to craft malicious input that alters the intended SQL query logic, potentially bypassing authentication entirely or extracting sensitive information from the database.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where untrusted data is sent to an interpreter as part of a command or query.

Root Cause

The root cause of this vulnerability is the absence of proper input validation and sanitization in the authentication mechanism. The application directly uses user-supplied data in SQL query construction without implementing defensive measures such as:

• Prepared statements with parameterized queries
• Input validation and sanitization
• Escape sequences for special characters
• Stored procedures for database operations

This architectural flaw allows attackers to break out of the intended query context and execute arbitrary SQL commands against the backend database.

Attack Vector

The attack can be launched remotely over the network without requiring authentication or user interaction. An attacker can manipulate the Username field in the login form at /index.php to inject SQL syntax that modifies the query's behavior.

Common exploitation techniques for this type of vulnerability include:

• Authentication Bypass: Injecting SQL logic to return a true condition (e.g., ' OR '1'='1) to bypass login validation
• Union-Based Extraction: Using UNION SELECT statements to retrieve data from other database tables
• Error-Based Enumeration: Triggering database errors to infer schema information
• Blind SQL Injection: Using boolean or time-based techniques to extract data character by character

The exploit has been publicly disclosed and documented, increasing the risk of active exploitation against unpatched systems.

Detection Methods for CVE-2025-7164

Indicators of Compromise

• Unusual login attempts containing SQL metacharacters such as single quotes ('), double dashes (--), semicolons (;), or OR 1=1 patterns
• Database error messages appearing in application logs or responses indicating query syntax errors
• Unexpected database queries or access patterns in database audit logs
• Multiple failed authentication attempts followed by successful login from the same source IP
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in POST parameters
• Monitor application logs for anomalous requests to /index.php containing suspicious characters in the Username field
• Implement database activity monitoring to detect unusual query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for common SQL injection payloads
• Enable detailed logging on the web server to capture full request parameters for forensic analysis

Monitoring Recommendations

• Establish baseline metrics for authentication attempts and alert on deviations
• Monitor database server CPU and query execution times for signs of time-based SQL injection attacks
• Review web server access logs regularly for requests containing URL-encoded SQL characters
• Implement real-time alerting for database errors that may indicate injection attempts

How to Mitigate CVE-2025-7164

Immediate Actions Required

• Restrict network access to the Cyber Cafe Management System to trusted IP addresses only
• Implement a Web Application Firewall with SQL injection protection rules in front of the application
• Monitor authentication logs for signs of exploitation attempts
• Consider taking the application offline until a patch is available or mitigations are in place
• Review database logs for evidence of prior exploitation

Patch Information

At the time of publication, no official patch has been released by the vendor for this vulnerability. Organizations using PHPGurukul Cyber Cafe Management System 1.0 should monitor the vendor's official channels for security updates. Additional technical details are available through the GitHub Issue Discussion and VulDB entry.

Workarounds

• Implement input validation at the application level to reject usernames containing SQL metacharacters
• Deploy a reverse proxy with ModSecurity or similar WAF capabilities configured with OWASP Core Rule Set
• Restrict database user privileges to minimum required operations, preventing DROP, DELETE, or administrative commands
• Consider modifying the application source code to use prepared statements with parameterized queries for all database interactions
• Implement network segmentation to isolate the application and database servers from other systems
