tid-213
Vulnerability from emb3d
Type
Description
To avoid the weaknesses of a shared secret verification (see TID-212), devices may utilize a digital signature verification scheme based on asymmetric public key cryptography. However, if the device does not correctly verify a firmware/software signature correctly, a threat actor can bypass the device’s authenticity checking mechanisms to upload malicious or corrupt version. The unauthorized firmware could “brick” the device, preventing it from being reset. This could also be used to install malicious logic on the device. NOTE: firmware/software signature here refers to processes that use cryptographic keys to verify firmware integrity and origin. These can include keyed hashes and/or asymmetric key signing. This does not include encrypting firmware with no other integrity verification mechanisms in-place.

Summary
A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.
