CVE-2025-5367 Overview
A critical SQL injection vulnerability has been identified in PHPGurukul Online Shopping Portal Project version 1.0. The vulnerability exists in the /category.php file, where improper handling of the Product parameter allows 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
Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive database information including customer data, order details, and administrative credentials without requiring any authentication.
Affected Products
- PHPGurukul Online Shopping Portal version 1.0
- Deployments using the vulnerable /category.php endpoint

Technical Details for CVE-2025-5367
Vulnerability Analysis
This vulnerability is classified as SQL Injection (CWE-89) with an underlying Injection flaw (CWE-74). The vulnerable endpoint /category.php fails to properly sanitize user-supplied input in the Product parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the same privileges as the application.
The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Since the vulnerability can be exploited remotely without authentication, any publicly accessible instance of the Online Shopping Portal is at risk.
Root Cause
The root cause of this vulnerability is inadequate input validation and the absence of parameterized queries or prepared statements in the /category.php file. When user input from the Product parameter is directly concatenated into SQL queries without proper sanitization or escaping, it creates a direct path for SQL injection attacks. This is a common web application security flaw that can be prevented through secure coding practices.
Attack Vector
The attack is network-based and requires no prior authentication or user interaction. An attacker can craft a malicious HTTP request targeting the /category.php endpoint with a specially crafted Product parameter containing SQL injection payloads. The vulnerability allows attackers to perform various database operations including data extraction, data modification, authentication bypass, and in some cases, command execution on the underlying server.
The injection occurs through the Product parameter in /category.php. An attacker can manipulate this parameter to include SQL syntax that alters the intended query logic. Common exploitation techniques include UNION-based injection for data extraction, boolean-based blind injection for data enumeration, and time-based blind injection when no visible output is available. For detailed technical analysis, refer to the GitHub Issue Report and VulDB #310660.
Detection Methods for CVE-2025-5367
Indicators of Compromise
- Unusual SQL error messages in web server logs or application error logs
- HTTP requests to /category.php containing SQL keywords such as UNION, SELECT, OR 1=1, single quotes, or comment sequences (--, #)
- Database query logs showing unexpected or malformed queries originating from the application
- Unexplained database modifications or new administrative accounts
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the Product parameter
- Implement application-level logging to capture all requests to /category.php with parameter values
- Enable database query auditing to identify anomalous query patterns
- Use intrusion detection systems (IDS) with signatures for SQL injection attack patterns
Monitoring Recommendations
- Monitor web server access logs for requests to /category.php with suspicious parameter values
- Set up alerts for database errors that may indicate injection attempts
- Regularly review database audit logs for unauthorized data access or modifications
- Implement real-time monitoring for authentication bypass attempts or privilege escalation
How to Mitigate CVE-2025-5367
Immediate Actions Required
- Restrict access to the /category.php endpoint until a patch is applied
- Implement input validation to reject requests containing SQL metacharacters
- Deploy WAF rules to block common SQL injection payloads
- Review database logs for evidence of past exploitation
Patch Information
As of the last NVD update on 2025-06-03, no official vendor patch has been released for this vulnerability. Organizations should monitor the PHP Gurukul Website for security updates. In the absence of an official patch, implementing the recommended workarounds is critical to reduce exposure.
Workarounds
- Implement parameterized queries or prepared statements in the /category.php file to prevent SQL injection
- Add server-side input validation to sanitize the Product parameter and reject malicious input
- Deploy a Web Application Firewall with SQL injection detection rules in front of the application
- Restrict database user privileges to limit the impact of successful exploitation
- Consider taking the affected functionality offline until proper fixes are implemented
# Example .htaccess rules to block common SQL injection patterns
RewriteEngine On
RewriteCond %{QUERY_STRING} (\%27)|(\')|(\-\-)|(\%23)|(#) [NC,OR]
RewriteCond %{QUERY_STRING} (union|select|insert|delete|drop|update|exec|cast) [NC]
RewriteRule ^category\.php$ - [F,L]
