CVE-2024-2495

Encrypted-data compromise via firmware-embedded cryptographic key

Published Mar 15, 2024 · Updated Aug 1, 2024

A hard-coded cryptographic key in FriendlyElec FriendlyWrt 2022-11-16.51b3d35 allows local users to compromise encrypted data. The firmware embeds a cryptographic key, but published material does not identify its file or function, the operation that consumes it, or how it becomes accessible. Exploitation requires local low-privileged access and permits confidentiality and integrity compromise without a reported availability impact.
