Affected: Moxa EDR-G9010 Series, Moxa EDR-8010 Series, Moxa EDF-G1002-BP Series, Moxa TN-4900 Series, Moxa NAT-102 Series, Moxa NAT-108 Series, Moxa OnCell G4302-LTE4 Series

An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A critical authorization flaw in the API allows an authenticated, low-privileged user to create a new administrator account, including accounts with usernames identical to existing users. In certain scenarios, this vulnerability could allow an attacker to gain full administrative control over the affected device, leading to potential account impersonation. While successful exploitation can severely impact the confidentiality, integrity, and availability of the affected device itself, there is no loss of confidentiality or integrity within any subsequent systems.
