CVE-2020-22658 is a firmware integrity and secure-boot bypass issue affecting multiple Ruckus wireless access points, SmartCell Gateway, SmartZone, Virtual SmartZone, and ZoneDirector products. The flaw allows an attacker to switch a device to an unauthorized firmware image and have that image boot as the primary verified image. In practical terms, the vulnerability undermines the trust model for firmware verification by permitting replacement or promotion of an untrusted image into the boot path, enabling persistent compromise of the affected device.
