CVE-2024-24567

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. Vyper compiler allows passing a value in builtin raw_call even if the call is a delegatecall or a staticcall. But in the context of delegatecall and staticcall the handling of value is not possible due to the semantics of the respective opcodes, and vyper will silently ignore the value= argument. If the semantics of the EVM are unknown to the developer, he could suspect that by specifying the `value` kwarg, exactly the given amount will be sent along to the target. This vulnerability affects 0.3.10 and earlier versions.

Summary
  • (es) Vyper es un Smart Contract Language pythonico para la máquina virtual ethereum. El compilador de Vyper permite pasar un valor en raw_call incorporado incluso si la llamada es una llamada delegada o una llamada estática. Pero en el contexto de delegarcall y staticcall el manejo del valor no es posible debido a la semántica de los respectivos códigos de operación, y vyper ignorará silenciosamente el argumento value=. Si el desarrollador desconoce la semántica del EVM, podría sospechar que al especificar el "valor" kwarg, se enviará exactamente la cantidad dada al objetivo. Esta vulnerabilidad afecta a la versión 0.3.10 y versiones anteriores.
