CVSS v2.0
9.4
Critical
| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:N |
Name of the Vulnerable Software and Affected Versions
Elliptic package versions prior to 6.5.6
Description
The issue concerns the Elliptic package for Node.js, specifically the EDDSA implementation. It 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. The
verify function in lib/elliptic/eddsa/index.js omits sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg() validation. This could have a security-relevant impact if an application relies on the uniqueness of a signature.Recommendations
For Elliptic package versions prior to 6.5.6, update to version 6.5.6 or later to resolve the issue. As a temporary workaround, consider disabling the
verify function in lib/elliptic/eddsa/index.js until a patch is available. Restrict the use of the EDDSA implementation to minimize the risk of exploitation.Fix
Improper Verification of Cryptographic Signature
