Description

An improper input validation vulnerability in go-attestation before 0.3.3 allows local users to provide a maliciously-formed Quote over no/some PCRs, causing AKPublic.Verify to succeed despite the inconsistency. Subsequent use of the same set of PCR values in Eventlog.Verify lacks the authentication performed by quote verification, meaning a local attacker could couple this vulnerability with a maliciously-crafted TCG log in Eventlog.Verify to spoof events in the TCG log, hence defeating remotely-attested measured-boot. We recommend upgrading to Version 0.4.0 or above.

Go-Attestation Improper Input Validation with attacker-controlled TPM Quote

GHSA-99cg-575x-774p

Advisory Details

### Impact An improper input validation vulnerability in go-attestation before 0.4.0 allows local users to provide a maliciously-formed Quote over no/some PCRs, causing `AKPublic.Verify` to succeed despite the inconsistency. Subsequent use of the same set of PCR values in `Eventlog.Verify` lacks the authentication performed by quote verification, meaning a local attacker could couple this vulnerability with a maliciously-crafted TCG log in `Eventlog.Verify` to spoof events in the TCG log, hence defeating remotely-attested measured-boot. ### Patches This issue is resolved in version 0.4.0. If your usage of this library verifies PCRs using multiple quotes, make sure to use the new method `AKPublic.VerifyAll()` instead of `AKPublic.Verify`.
