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

This vulnerability is a SQL injection flaw in the Payroll System 1.0 application. It exists in the Login function of the admin_class.php file where the Username argument is manipulated. The attack allows remote execution of malicious SQL commands through unsanitized user input, potentially bypassing authentication.

Detection Guidance

To detect SQL injection vulnerabilities like CVE-2026-78201, test the login endpoint with crafted inputs such as admin'# or ' OR 1=1 LIMIT 1# in the username field. Use tools like sqlmap to automate detection by sending these payloads to /ajax.php?action=login. Check server logs for unusual SQL query patterns or errors indicating injection attempts.

Impact Analysis

An attacker could exploit this to bypass login, gain admin access, and steal sensitive data like employee PII, salaries, and attendance records. Passwords are stored in plaintext, making credential theft easier. The system could also be manipulated to alter or delete critical payroll data.

Compliance Impact

This vulnerability likely violates GDPR due to unauthorized access to personal data and HIPAA if employee health or salary data is exposed. It results in non-compliance with data protection requirements for confidentiality and integrity of sensitive information.

Mitigation Strategies

Immediately update the application to use prepared statements with parameterized queries instead of direct variable concatenation. Hash all passwords using bcrypt or a similar algorithm. Disable unauthenticated access to ajax.php if possible. Apply input validation to sanitize all user-supplied data before processing.
