CVE-2024-48915 Information

Description

Agent Dart is an agent library built for Internet Computer for Dart and Flutter apps. Prior to version 1.0.0-dev.29 certificate verification in lib/agent/certificate.dart does not occur properly. During the delegation verification in the _checkDelegation function the canister_ranges aren’t verified. The impact of not checking the canister_ranges is that a subnet can sign canister responses in behalf of another subnet. The certificate’s timestamp i.e /time path is also not verified meaning that the certificate effectively has no expiration time. Version 1.0.0-dev.29 implements appropriate certificate verification.
