Information disclosure via binary buffer overrun
Published Sep 27, 2022 · Updated May 21, 2025
Stack-based buffer overflow in Western Digital network-storage firmware before 8.10.0-117 allows local access to read /etc/version via crafted input. An insecure binary operation overruns a stack buffer and can expose adjacent memory or alter execution state. Exploitation requires a chained issue, remote code execution, high privileges, and user interaction; reported consequences are information exposure, file modification, memory errors, or device crashes.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
