CVE-2023-27206Network attack vector

Victim-session script execution via reflected page parameter

Published Mar 9, 2023 · Updated Feb 28, 2025

Cross-site scripting in Best POS Management System 1.0 allows remote attackers to execute script in a victim's browser through a crafted URL. The /kruxton/navbar.php endpoint places the page query parameter into generated HTML without neutralizing script-capable content. Exploitation is unauthenticated but requires a victim to open the crafted page, allowing the injected script to read or alter data available to the victim's session.
