Executive Summary

[{'type': 'paragraph', 'content': "CVE-2026-4533 is a Time-Based Blind SQL Injection vulnerability found in version 1.0 of the Simple Food Ordering System developed by Code-Projects. It exists in the 'status' parameter of the /food/all-tickets.php endpoint due to improper input validation and sanitization."}, {'type': 'paragraph', 'content': 'This vulnerability allows attackers to inject malicious SQL code, including time-delay functions like SLEEP(), which causes a measurable delay in server response, confirming the presence of the blind SQL injection.'}, {'type': 'paragraph', 'content': 'Exploiting this flaw, attackers can enumerate database schema, extract sensitive data such as administrator credentials, bypass authentication, modify or delete database records, and potentially gain full administrative access to the application and its database.'}] [1]

Impact Analysis

This vulnerability can have serious impacts including unauthorized access to sensitive information, such as administrator credentials, which can lead to data breaches.

Attackers can bypass authentication mechanisms, allowing them to impersonate legitimate users or administrators.

They can modify or delete database records, potentially disrupting business operations or corrupting data integrity.

Ultimately, attackers may gain full administrative control over the application and its database, leading to complete system compromise.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by testing the `status` parameter of the `/food/all-tickets.php` endpoint for time-based blind SQL injection. An effective method is to inject a payload that causes a delay in the server response, such as using the SQL function SLEEP().'}, {'type': 'paragraph', 'content': "For example, sending an HTTP GET request with a payload like `status=1' AND SLEEP(15)--` will cause the server to delay its response by approximately 15 seconds if the vulnerability is present."}, {'type': 'paragraph', 'content': 'This delay confirms the presence of the blind SQL injection vulnerability.'}, {'type': 'paragraph', 'content': 'You can use command-line tools such as curl to test this manually:'}, {'type': 'list_item', 'content': 'curl -i "http://target/food/all-tickets.php?status=1\'%20AND%20SLEEP(15)--"'}, {'type': 'paragraph', 'content': 'If the response time is significantly longer (around 15 seconds), it indicates the vulnerability.'}] [1]

Mitigation Strategies

[{'type': 'paragraph', 'content': 'Immediate mitigation steps include:'}, {'type': 'list_item', 'content': 'Use prepared statements and parameterized queries to prevent SQL injection, for example: `$stmt = $pdo->prepare("SELECT * FROM tickets WHERE status = ?"); $stmt->execute([$status]);`.'}, {'type': 'list_item', 'content': 'Validate and sanitize all user inputs rigorously to ensure no malicious SQL code can be injected.'}, {'type': 'list_item', 'content': 'Apply the principle of least privilege to the database user accounts used by the application, limiting their permissions.'}, {'type': 'list_item', 'content': 'Deploy a Web Application Firewall (WAF) to detect and block SQL injection attempts.'}] [1]
