CVE-2025-1643Public exploitNetwork attack vector

Account takeover via forged password-change GET

Published Feb 25, 2025 · Updated Feb 25, 2025

Cross-site request forgery in Benner Sistemas ModernaNet before 1.1.1 allows remote attackers to change an authenticated user's password. The /DadosPessoais/SG_AlterarSenha endpoint accepts a GET request whose novaSenha parameter directly sets the session user's new password. Exploitation requires luring an authenticated user to attacker-controlled content that submits the request, after which the attacker knows the replacement password.
