Executive Summary

CVE-2026-125078 is a session fixation vulnerability in SourceCodester Smart Attendance System with QR Code Scanner 1.0. The login.php file starts a session but does not regenerate the session ID after login. This allows an attacker to set a session ID in a victim's browser before authentication. When the victim logs in, the attacker can reuse the same session ID to gain unauthorized access to an administrator account without stealing credentials.

Detection Guidance

To detect session fixation in Smart Attendance System with QR Code Scanner 1.0, inspect login.php for session handling. Check if session_regenerate_id() is missing after authentication. Monitor for unauthorized session reuse by tracking PHPSESSID cookies and admin session persistence.

Impact Analysis

An attacker could gain full administrative access to the system by exploiting this vulnerability. This allows them to perform unauthorized actions, bypass logout controls, and maintain silent persistence. The attack can be executed remotely and requires the victim to visit a malicious link or be on an unsecured network.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA compliance. GDPR requires protection of personal data, while HIPAA mandates secure access to health information. A breach could result in legal penalties, data loss, and reputational damage.

Mitigation Strategies

Immediately update login.php to call session_regenerate_id(true) after successful login. Set HttpOnly, Secure, and SameSite=Strict flags for session cookies. Disable plaintext HTTP to prevent MITM attacks. Monitor for suspicious session reuse or admin account activity.
