Taiwan’s Moxa has warned of two security vulnerabilities affecting cellular routers, secure routers, and network security devices that could allow elevation of privilege and command execution.
The list of vulnerabilities is as follows –
- CVE-2024-9138 (CVSS Score 4.0: 8.6) – A hard-coded credential vulnerability that could allow an authenticated user to elevate privileges and gain root access to the system, leading to system compromise, unauthorized modification, data disclosure, or service failure
- CVE-2024-9140 (CVSS Score 4.0: 9.3) – The vulnerability allows attackers to use special characters to bypass input restrictions, which could lead to unauthorized command execution
The vulnerabilities, reported by security researcher Lars Howlin, affect the following products and firmware versions –
- CVE-2024-9138 – EDR-810 series (Firmware version 5.12.37 and earlier), EDR-8010 series (Firmware version 3.13.1 and earlier), EDR-G902 series (Firmware version 5.7.25 and earlier), EDR-G902 series (Firmware version 5.7.25 and earlier), EDR-G9004 series (firmware version 3.13.1 and earlier), EDR-G9010 series (firmware version 3.13.1 and earlier), EDF-G1002-BP series (firmware version 3.13.1 and earlier), NAT-102 series (firmware version 1.0.5 and earlier) , OnCell G4302-LTE4 series (Firmware version 3.13 and earlier) and TN-4900 Series (firmware version 3.13 and earlier)
- CVE-2024-9140 – EDR-8010 series (Firmware version 3.13.1 and earlier), EDR-G9004 series (Firmware version 3.13.1 and earlier), EDR-G9010 series (Firmware version 3.13.1 and earlier), EDF-G1002-BP series ( Firmware version 3.13.1 and earlier), NAT-102 series (firmware version 1.0.5 and earlier), OnCell G4302-LTE4 series (firmware version 3.13 and earlier) and TN-4900 series (firmware version 3.13 and earlier)
Patches were available for the following versions –
