Executive Summary

This vulnerability is a critical SQL injection flaw in the user login functionality of the code-projects Online Product Reservation System version 1.0. It occurs because the application directly concatenates user-supplied input from the 'emailadd' parameter into an SQL query without proper validation or sanitization. This allows attackers to inject malicious SQL code remotely, bypass authentication, and gain unauthorized access to sensitive user data stored in the database. The issue is located in the file app/user/login.php. [1, 2]

Detection Guidance

This vulnerability can be detected by testing the 'emailadd' parameter in the login functionality (app/user/login.php) for SQL injection. One method is to use SQL injection testing tools or manual injection attempts with payloads such as ' OR '1'='1 to see if authentication can be bypassed. Additionally, attackers can be identified by monitoring for suspicious requests targeting 'app/user/login.php' with unusual input in the 'emailadd' parameter. Google dorking with queries like 'inurl:app/user/login.php' can help identify vulnerable endpoints externally. Specific commands for detection include using curl or sqlmap, for example: curl -X POST -d "emailadd=' OR '1'='1" https://target/app/user/login.php or sqlmap -u "https://target/app/user/login.php" --data="emailadd=test" --risk=3 --level=5. These approaches help confirm if the SQL injection vulnerability exists. [2]

Mitigation Strategies

Immediate mitigation steps include replacing or patching the affected component or product, as no known mitigations or countermeasures have been documented. It is critical to sanitize and validate all user inputs, especially the 'emailadd' parameter in app/user/login.php, to prevent SQL injection. Applying input validation, using prepared statements or parameterized queries, and avoiding direct concatenation of user input into SQL queries are recommended. If patching is not immediately possible, restricting access to the vulnerable login page or implementing Web Application Firewall (WAF) rules to block malicious SQL injection attempts can help reduce risk.

Compliance Impact

The vulnerability allows attackers to bypass authentication and gain unauthorized access to sensitive user data, which can lead to breaches of confidentiality, integrity, and availability of personal information. Such unauthorized access and potential data breaches can result in non-compliance with common standards and regulations like GDPR and HIPAA, which mandate protection of personal and sensitive data. Therefore, this vulnerability poses a significant risk to compliance with these regulations. [1, 2]
