Weakness
CWE-353: Missing Support for Integrity Check
The product uses a transmission protocol that does not include a mechanism for verifying the integrity of the data during transmission, such as a checksum.
How to prevent it
- Architecture and Design: Add an appropriately sized checksum to the protocol, ensuring that data received may be simply validated before it is parsed and used.
- Implementation: Ensure that the checksums present in the protocol design are properly implemented and added to each message before it is sent.
