CVE-2019-25057Network attack vector

Data integrity violation via attacker-controlled CustomSerializer

Published Feb 14, 2022 · Updated Aug 5, 2024

Data-integrity failure in R3 Corda before 4.1 allows remote attackers to alter serialized data semantics through a crafted CustomSerializer. The CustomSerializer processing path reconstructs received data with attacker-selected semantics; public sources disclose no narrower function or missing validation. Exploitation requires serialized input to reach that serializer, and the published impact is limited to modifying data meaning.
