Online Lot Reservation System SQL Injection Vulnerability

A SQL injection vulnerability, identified as CVE-2026-7131, has been discovered in code-projects Online Lot Reservation System version 1.0 and earlier. This vulnerability is located in the /loginuser.php file and can be exploited by manipulating the email and password arguments. Successful exploitation could allow a remote attacker to execute arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion. The vulnerability is remotely exploitable and a public exploit is available, increasing the risk of exploitation. Due to the sensitive nature of lot reservation data, organizations using this system are at risk of significant data compromise.

Attack Chain

1. An attacker identifies a vulnerable instance of code-projects Online Lot Reservation System version 1.0.
2. The attacker crafts a malicious HTTP request targeting the /loginuser.php file.
3. Within the request, the attacker injects SQL code into the email or password parameters.
4. The application fails to properly sanitize the input, passing the malicious SQL code to the database.
5. The database executes the injected SQL code, treating it as a legitimate query.
6. The attacker gains unauthorized access to the database, potentially reading sensitive information such as user credentials, reservation details, or financial data.
7. The attacker may modify or delete data within the database, disrupting the system’s functionality.
8. The attacker can potentially use the compromised database to pivot to other systems or escalate privileges within the network.

Impact

Successful exploitation of CVE-2026-7131 can result in unauthorized access to sensitive data within the Online Lot Reservation System. This could include user credentials, reservation details, and financial information. The vulnerability affects systems running code-projects Online Lot Reservation System up to version 1.0. Due to the availability of a public exploit, the risk of exploitation is elevated. A successful attack could lead to data breaches, financial loss, and reputational damage.

Recommendation

• Apply appropriate input validation and sanitization techniques to prevent SQL injection attacks within the /loginuser.php file.
• Deploy the Sigma rule Detect SQL Injection Attempt via Login to identify potential exploitation attempts against the /loginuser.php endpoint.
• Monitor web server logs for suspicious requests targeting the /loginuser.php file, specifically looking for SQL syntax within the email or password parameters.
• Review and harden database access controls to limit the impact of successful SQL injection attacks.
• Implement a web application firewall (WAF) with rules to detect and block SQL injection attempts.
• Disable Javascript to ensure complete website functionality.
