CVE-2024-48949
MEDIUM5.3EPSS 0.29%Elliptic's verify function omits uniqueness validation
發布日:2024/10/10修改日:2025/11/27
描述
The Elliptic package 6.5.5 for Node.js for EDDSA implementation does not perform the required check if the signature proof(s) is within the bounds of the order n of the base point of the elliptic curve, leading to signature malleability. Namely, the `verify` function in `lib/elliptic/eddsa/index.js` omits `sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()` validation. This vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.
