CVE-2022-0317
Improper input validation in github.com/google/go-attestation
4.0
MEDIUM
CVSS 3.1
EPSS 0.04%
描述
A local attacker can defeat remotely-attested measured boot. Improper input validation in AKPublic.Verify can cause it to succeed when provided with a maliciously-formed Quote over no/some PCRs. Subsequent use of the same set of PCR values in Eventlog.Verify lacks the authentication performed by quote verification, meaning a local attacker can couple this vulnerability with a maliciously-formed TCG log in Eventlog.Verify to spoof events in the TCG log, defeating remotely-attested measured-boot.
