CVE-2022-23771

Account deletion and privilege escalation via CSRF

Published Oct 17, 2022 · Updated May 9, 2025

CSRF in EFM Networks IPTIME NAS firmware before 1.4.86 allows remote attackers to delete accounts or escalate user privileges. Account-creation and deletion pages accept POST requests without validating that they originated from an authorized user action. Exploitation requires user interaction and adjacent-network access, and the resulting requests can alter privileges or remove NAS user accounts.
