1.0.0-dev.29- Upgrade agent_dart to this version or later
Description
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
Affected versions

| Package | Vulnerable | Fixed in |
|---|---|---|
| agent_dart | < 1.0.0-dev.29 |
1.0.0-dev.29 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-295: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How to prevent it
- Architecture and Design, Implementation: Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- Implementation: If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CWE-347: Improper Verification of Cryptographic Signature
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
