CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-85402 is a SQL injection vulnerability in the Doctor Appointment System 1.0. It affects the /patient/booking.php file where the doc_id parameter is improperly validated. Attackers can inject malicious SQL queries remotely without authentication, potentially accessing or altering database contents.

Detection Guidance

To detect this SQL injection vulnerability, test the /patient/booking.php endpoint with payloads like doc_id=1 AND (SELECT 2765 FROM (SELECT(SLEEP(5)))MLXc). If the response is delayed by 5 seconds, the vulnerability likely exists. Use tools like curl or sqlmap for automated testing.

Impact Analysis

This vulnerability allows attackers to access sensitive data, modify or delete records, and potentially take control of the system. If exploited, it could lead to unauthorized access to patient information, appointment details, or other confidential data stored in the database.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA by exposing protected health information (PHI) or personal data. It could result in data breaches, unauthorized disclosures, and failure to meet regulatory requirements for data security and patient privacy.

Mitigation Strategies

Immediately implement prepared statements with parameter binding for all database queries. Apply strict input validation to sanitize the doc_id parameter. Restrict database user permissions to the minimum required. Conduct a full security audit of the application.
