CVE-2024-48915
Agent Dart missing certificate verification checks
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.

Agent Dart is missing certificate verification checks
Certificate verification (in lib/agent/certificate.dart) has been found to contain two issues:
- During the delegation verification (in _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. You have more details in the IC specification here. Also for reference you can check how is this implemented in the agent-rs. - The certificate’s timestamp, i.e /time path, is not verified, meaning that the certificate effectively has no expiration time. The IC spec doesn’t specify an expiry times, it gives some suggestions, quoting: "A reasonable expiry time for timestamps in R.signatures and the certificate Cert is 5 minutes (analogously to the maximum allowed ingress expiry enforced by the IC mainnet). Delegations require expiry times of at least a week since the IC mainnet refreshes the delegations only after replica upgrades which typically happen once a week". For reference you can check how is this implemented in the agent-rs (here and here).
Additionally, seems replica signed queries aren’t implemented
