CVE-2024-37386

Protected-data exposure via secure-boot bypass

Published Jul 15, 2024 · Updated Aug 2, 2024

Secure-boot bypass in Stormshield Network Security allows physically proximate attackers to restart into single-user mode. Unspecified manipulations defeat the secure-boot restriction on single-user startup; Stormshield has not disclosed the underlying boot-path operation. Physical access and a high-complexity sequence are required, and successful access exposes protected firewall data without reported integrity or availability impact.
