Local firmware compromise via WebSetServiceCfg buffer overflow
Published Feb 8, 2021 · Updated Aug 3, 2024
Buffer overflow in HPE Apollo 70 System BMC firmware before 3.0.14.0 allows local users to compromise the controller via service configuration input. The libifc.so WebSetServiceCfg function copies service-configuration data into a fixed-size buffer without verifying that the input fits. Low-privilege local access is required; successful exploitation can read or alter BMC data and interrupt controller service.
