CVE-2021-25131

Local memory corruption via firmware image location handling

Published Jan 29, 2021 · Updated Aug 3, 2024

A local buffer overflow in HPE Cloudline BMC firmware allows local users to corrupt memory through firmware image location handling. The flaw resides in the spx_restservice setFWImageLocation_func function, but HPE has not published the input field, buffer operation, or overflow boundary. Exploitation requires low privileges on an affected server; HPE describes the issue as local and reports denial of service among the bulletin's potential impacts.
