CVE-2024-24567 raw_call `value=` kwargs not disabled for static and delegate calls

What is CVE-2024-24567?

CVE-2024-24567 is a medium-severity vulnerability in vyperlang vyper, published on 30 Jan 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

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.

Weakness: CWE-754
