Description

The bootloader in the Nokia ASIK AirScale system module (versions 474021A.101 and 474021A.102) loads public keys for firmware verification signature. If an attacker modifies the flash contents to corrupt the keys, secure boot could be permanently disabled on a given device.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality none, integrity high, availability high.
