CVE-2022-31886Public exploitNetwork attack vector

2FA disabling via cross-site request forgery

Published Jun 28, 2022 · Updated Aug 3, 2024

Cross-site request forgery in Marval MSM 14.19.0.12476 allows remote attackers to disable two-factor authentication via a malicious form. Public sources do not identify the affected endpoint or disclose which anti-CSRF validation is absent; they establish only that a malicious form can trigger the 2FA-disable action. Exploitation requires a logged-in user to submit the attacker's form, after which that account's second factor is disabled.
