CVE-2006-1538: The Enova X-Wall ASIC encrypts with a key obtained via Microwire from a serial EEPROM that stores the key i...

Security readout for executives and security teams

This CVE describes a hardware encryption design weakness: the device stores or transports the encryption key in cleartext, so someone with physical access could recover it. If an organization still relies on affected Enova X-Wall ASIC hardware, encrypted data may not provide the expected protection. Exposure is likely limited to organizations still using Enova X-Wall ASIC-based hardware encryption tokens or products. The bundle lists vendor, product, and versions as unavailable, so asset confirmation is required. Prioritize discovery before emergency response. This is serious where the hardware is present, because it can undermine encryption, but the available evidence indicates physical access is required and affected products are not fully identified. Mitigation focus: Identify any Enova X-Wall ASIC-based encryption hardware in use.; Check vendor or product guidance for replacement, firmware, or compensating controls.; Restrict physical access to affected tokens, encrypted drives, and hardware modules..
