CWE ID 252


CVE-2023-37902 is a vulnerability affecting the Vyper programming language prior to version 0.3.10, which targets the Ethereum Virtual Machine (EVM). The issue lies in the ecrecover precompile, where if the signature does not verify, the output buffer is not filled. However, the ecrecover builtin still returns whatever is at memory location 0. This means that by manipulating data at memory location 0 just before the ecrecover, a signature check might pass on an invalid signature. The vulnerability has a risk score of 25 and a base severity of MEDIUM. To remediate it, users should update to version 0.3.10 or later. This vulnerability poses a potential danger to organizations using Vyper as it could lead to passing invalid signatures and compromising security.
