Remote code execution in Indy-Node's pool-upgrade transaction

Critical
WadeBarnes published GHSA-r6v9-p59m-gj2p Sep 2, 2022

Package

indy-node (Hyperledger)

Affected versions

<=1.12.4

Patched versions

>=1.12.5

Description

Impact

The pool-upgrade request handler in Indy-Node <=1.12.4 allows an improperly authenticated attacker to remotely execute code on nodes within the network.

Network operators are strongly encouraged to upgrade to the latest Indy-Node release >=1.12.5 as soon as possible.

Patches

The pool-upgrade request handler in Indy-Node >=1.12.5 has been updated to properly authenticate pool-upgrade transactions before any processing is performed by the request handler. The transactions are further sanitized to prevent remote code execution.

Mitigations

Network operators are strongly encouraged to upgrade to the latest Indy-Node release >=1.12.5 as soon as possible.

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.
