CVE-2021-25171

Local memory corruption via license configuration overflow

Published Feb 8, 2021 · Updated Aug 3, 2024

A local buffer overflow in HPE Apollo 70 System BMC firmware before 3.0.14.0 allows local users to corrupt process memory. The libifc.so WebSetLicenseCfg function writes license-configuration input beyond a buffer, but HPE has not disclosed the affected field or copy operation. Low-privileged local access is required, and HPE has not specified whether exploitation causes a crash, code execution, or another consequence.
