Vulnerability from variot - Updated: 2025-03-12 23:24

OnCell G3470A-LTE Series firmware versions v1.7.7 and prior have been identified as vulnerable due to missing bounds checking on buffer operations. An attacker could write past the boundaries of allocated buffer regions in memory, causing a program crash. ONCELLG3470A-LTE-EU-T firmware, ONCELLG3470A-LTE-EU firmware, OnCellG3470A-LTE-US-T firmware etc. Moxa Inc. The product contains a classic buffer overflow vulnerability.Information is tampered with and service operation is interrupted (DoS) It may be in a state. MOXA OnCell G3470A-LTE is a series of cellular gateways/routers from China's MOXA company.

MOXA OnCell G3470A-LTE v1.7.7 and earlier firmware versions have a buffer overflow vulnerability. The vulnerability is caused by the lack of boundary checks on buffer operations
