The certificate used to identify the Silver Peak Cloud Portal to EdgeConnect devices is not validated. This makes it possible for someone to establish a TLS connection from EdgeConnect to an untrusted portal.

1. IPSec UDP key material can be retrieved from machine-to-machine interfaces and human-accessible interfaces by a user with admin credentials. Such a user, with the required system knowledge, could use this material to decrypt in-flight communication. 2. The vulnerability requires administrative access and shell access to the EdgeConnect appliance. An admin user can access IPSec seed and nonce parameters using the CLI, REST APIs, and the Linux shell.

The certificate used to identify Orchestrator to EdgeConnect devices is not validated, which makes it possible for someone to establish a TLS connection from EdgeConnect to an untrusted Orchestrator.

A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious softw…
