Failure to validate signature during handshake

High severity GitHub Reviewed Published Mar 17, 2022 in ChainSafe/js-libp2p-noise • Updated Jan 27, 2023

Package

npm @chainsafe/libp2p-noise (npm)

Affected versions

< 4.1.2
>= 5.0.0, < 5.0.3

Patched versions

4.1.2
5.0.3

Description

Impact

@chainsafe/libp2p-noise before 4.1.2 and 5.0.3 was not correctly validating signatures during the handshake process.
This may allow a man-in-the-middle to pose as other peers and get those peers banned.

Patches

Users should upgrade to 4.1.2 or 5.0.3

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
