CVE-2025-9011 Overview
A SQL injection vulnerability has been identified in PHPGurukul Online Shopping Portal Project version 2.0. This vulnerability exists in the /shopping/signup.php file, where the emailid parameter is not properly sanitized before being used in database queries. This allows remote attackers to inject malicious SQL commands through the email input field during the user registration process, potentially compromising the entire database.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive user data, modify database contents, bypass authentication mechanisms, or potentially gain unauthorized access to the underlying server through database operations.
Affected Products
- PHPGurukul Online Shopping Portal Project version 2.0
- Installations with the vulnerable /shopping/signup.php endpoint exposed

Technical Details for CVE-2025-9011
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) stems from improper input validation in the user signup functionality. The emailid parameter in the /shopping/signup.php file is passed directly to SQL queries without adequate sanitization or parameterization. This creates a classic injection point where user-controlled input can modify the intended SQL query logic.
The vulnerability is network-accessible, requiring no authentication or user interaction to exploit. An attacker can craft malicious payloads in the email field during registration to manipulate backend database queries. The public disclosure of exploitation details increases the risk of active exploitation attempts against vulnerable installations.
Root Cause
The root cause is improper neutralization of special elements used in SQL commands (CWE-89) combined with inadequate injection mitigation (CWE-74). The application fails to implement proper input validation, prepared statements, or parameterized queries for the emailid parameter, allowing attacker-controlled input to break out of the intended data context and execute arbitrary SQL commands.
Attack Vector
The attack is conducted remotely via the network by submitting specially crafted input to the signup form. An attacker would navigate to the registration page at /shopping/signup.php and inject SQL metacharacters through the email input field. Common exploitation techniques include:
The vulnerability can be exploited by injecting SQL syntax such as single quotes, boolean-based payloads, or UNION-based attacks into the emailid field. Successful exploitation could allow data exfiltration, authentication bypass, or database manipulation depending on the database configuration and privileges.

Detection Methods for CVE-2025-9011
Indicators of Compromise
- Web server logs showing unusual requests to /shopping/signup.php with SQL syntax in the emailid parameter
- Database logs indicating unexpected query patterns or errors related to the signup functionality
- Failed login attempts or new user accounts created with suspicious email addresses containing SQL metacharacters
- Unexpected database modifications or data exfiltration activity
Detection Strategies
- Implement web application firewall (WAF) rules to detect SQL injection patterns in form submissions
- Monitor HTTP POST requests to /shopping/signup.php for SQL injection indicators such as single quotes, UNION statements, or comment sequences
- Review database query logs for anomalous queries originating from the signup functionality
- Deploy intrusion detection signatures targeting common SQL injection payloads
Monitoring Recommendations
- Enable detailed logging for the /shopping/signup.php endpoint and associated database queries
- Configure alerting for database errors that may indicate injection attempts
- Monitor for unusual database activity such as bulk data access or schema enumeration
- Implement rate limiting on registration endpoints to slow automated exploitation attempts
How to Mitigate CVE-2025-9011
Immediate Actions Required
- Restrict access to the /shopping/signup.php endpoint until a patch is applied
- Implement web application firewall rules to block SQL injection attempts targeting the registration form
- Review database accounts and minimize privileges for the application database user
- Audit existing user accounts and database contents for signs of compromise
Patch Information
As of the last modification date, no official vendor patch has been released for this vulnerability. Administrators should monitor the PHPGurukul website for security updates. Given the publicly disclosed nature of this vulnerability, organizations using this software should prioritize implementing workarounds or consider alternative solutions until an official fix is available.
Workarounds
- Implement input validation and sanitization for the emailid parameter before database operations
- Modify the vulnerable code to use prepared statements with parameterized queries
- Deploy a web application firewall with SQL injection protection enabled for the affected endpoint
- Consider disabling the signup functionality temporarily if immediate registration is not business-critical
# Example WAF rule for ModSecurity to help mitigate SQL injection
