CVE-2022-36058Public exploitNetwork attack vector

Transaction integrity violation via empty function name

Published Sep 6, 2022 · Updated Apr 22, 2025

Improper input validation in MultiversX mx-chain-go before 1.3.34 allows remote attackers to alter transaction processing via crafted blocks. The VM-common smart-contract-call classifier accepts MultiESDTNFTTransfer data whose final function-name argument is empty, causing affected nodes to apply incorrect call semantics. Exploitation requires processing an attacker-controlled historical or live block; peer messaging, storage, and API requests remain unaffected.
