Controller DoS may occur due to buffer overflow when an error is generated in response to a specially crafted message. See Honeywell Security Notification for recommendations on upgrading and versioning.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
C300_firmware Honeywell 501.1 (including) 501.6hf8 (including)
C300_firmware Honeywell 510.1 (including) 510.2hf12 (including)
C300_firmware Honeywell 511.1 (including) 511.5tcu3 (including)
C300_firmware Honeywell 520.1 (including) 520.1tcu4 (including)
C300_firmware Honeywell 520.2 (including) 520.2tcu2 (including)

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
